The Tar Creek Superfund and Flood Map: A Case Study in the Equitable Co‐Production of Maps for Storytelling, Environmental Activism, and Education - Lively, M.; Jim, R.; Tran, J.; Hatley, E.; Meierdiercks, K. (Community Science, 2026)
Abstract Case studies on co‐production and geographic information systems have reported on the utility and value of community members contributing local knowledge for and providing feedback on maps in ways that can increase the accuracy and usability of the map. However, how the concept for and goals of the map are co‐produced and how the maps are then used by the community is understudied. This paper uses a co‐operative inquiry approach to assess equity in co‐production throughout the process of building and using the Tar Creek Superfund and Flood map for storytelling, environmental activism, and education. The project team designed and built an interactive flood map demonstrating that floodwaters flow through the Tar Creek Superfund site, potentially carrying and distributing mining waste throughout the community, further exacerbating the environmental harm the community has experienced as a result of mining. The team was formed through the Thriving Earth Exchange, which brings community leaders, volunteer scientists, and technical experts together to work on community‐driven projects. The purpose of this project was to both make—and use—the map dynamically within the community in pursuit of education and environmental activism goals. Equity is measured by assessing roles and labor not only within making the map but also within its various uses by community members. , Plain Language Summary This paper describes a collaborative partnership between technical experts and staff from a community‐based organization. The project team created and used a map to enhance storytelling and in the pursuit of environmental activism and education goals. The map shows that when it floods in Ottawa County, Oklahoma, water can flow through abandoned mining areas, picking up toxic mining waste that is then left in the community after the flood. The map has been used to show local government officials how flooding can harm the community and help teach residents about their flood risks. Roles and labor were distributed equitably throughout the project, contributing to its success. , Key Points The purpose of this project was to make—and use—a map dynamically within the community for storytelling and in pursuit of education and environmental activism goals Each team member contributed specialized knowledge, not only technical knowledge of geographic information systems but also an understanding of how to best use the map within a localized community Equity must be measured by assessing roles and labor not only within making the map but also within its various uses by community members

Displaced by conflict, threatened by fires and floods: a climate justice perspective on the Rohingya refugee crisis in Bangladesh - Ahmed, Saleh; Duran, Kendra (Environmental Research: Climate, 2026)
Abstract This article investigates the climate justice challenges faced by the Rohingya populations in Bangladesh. Drawing on forty semi-structured interviews with Rohingya refugees and members of the host community, this study highlights how fire, flooding, landslides, and waterlogging expose these communities to overlapping vulnerabilities. The Rohingya experience is illustrative of a broader displacement pattern in which people fleeing conflict are resettled into climate-vulnerable regions, as seen also in Darfur, Syria, and South Sudan. Their settlements, hastily established on deforested and degraded land, are highly susceptible to fires and monsoon hazards. These risks are intensified by structural inequities, resource scarcity, and limited adaptive capacity, raising urgent questions of distributive, procedural, recognition, and intergenerational justice. By situating the Rohingya case within global climate justice debates, this article provides insights into how systemic inequities intersect with environmental hazards in the lives of displaced populations.

Of droughts and flooding rains: koala population occupancy in a north-east New South Wales conservation reserve, and implications for range-wide surveys - Goldingay, Ross L. (Australian Mammalogy, 2026)
Population monitoring is fundamental to the conservation of threatened species such as the koala (Phascolarctos cinereus). This study extends by 2 years, a previous 8-year annual monitoring project of a koala population in north-east New South Wales. This study relied on audio-recorders and occupancy modelling to investigate whether the population has remained unaffected by the driest period on record followed by the wettest period on record. Audio-surveys were conducted at 42 sites over a 2-week period in each of 2022 and 2023. The probability of detection varied among types of audio-recorders, but averaged 0.45–0.88 per night, which equates to requiring 2–5 survey nights to have 95% confidence that koalas were detected. The probability of occupancy increased from 0.80 (95% CI, 0.66–0.94) in 2022 to 0.95 (95% CI, 0.89–1.0) in 2023. Local abundance of calling males detected by the more sensitive recorders increased from 1.6 ± 0.2 in 2022 to 2.2 ± 0.1 in 2023. The probability of occupancy when viewed across 10 years showed little change despite dramatic fluctuations in rainfall. This may reflect high local habitat suitability as well as occupancy being insensitive to variation in abundance because koalas are long-lived. Changes over time in the probability of detection may be more reflective of changes in abundance. This study highlights that the paucity of multi-year population studies on the koala means that our current understanding of koala population dynamics is inadequate for effective conservation.

Future Climate Change Assessment in Flood Risk Management: A Synthesis of Practices in Germany and the BeNeLux Countries - Macdonald, Elena; Merz, Bruno; Aerts, Jeroen C. J. H.; Dewals, Benjamin; Kwadijk, Jaap C. J.; Slager, Kymo; Willems, Patrick; Zoccatelli, Davide; Vorogushyn, Sergiy (Journal of Flood Risk Management, 2026)
ABSTRACT Climate change, with its links to an intensified water cycle, heavier rainfall, and potentially higher flood peaks, raises concerns about the adequacy of current flood risk management. The devastating July 2021 floods in western Europe underscored these concerns, highlighting the need for transboundary cooperation and shared expertise in adapting flood risk management to climate change. However, uncertainty in future flood projections presents challenges for agencies and governments in upgrading existing measures or designing new ones. Here, we review how climate change information is integrated into flood risk management, focusing on flood design values and flood hazard and risk maps. Focusing on Germany, The Netherlands, Belgium, and Luxembourg—the countries significantly impacted by the 2021 floods—we examine regional practices, as flood risk management is often organized at the sub‐national level. Specifically, we assess whether regions have published flood policy papers, developed future flooding scenarios under climate change, and translated these scenarios to flood hazard and risk maps and the design of protection measures. Our findings reveal that all 20 regions have adaptation plans addressing climate change and almost all regions have developed future flood projections but only three incorporate them into climate‐adjusted design values and only one provides flood hazard and risk maps under future climate scenarios. Assessments of the future climate vary widely. For example, Flanders in Belgium uses a full range of CMIP5 emission scenarios (RCP2.6 to RCP8.5), while Baden‐Württemberg and Bavaria in Germany rely on the worst‐case scenario (RCP8.5). Similarly, The Netherlands adopts an approach using 33 global climate models and a dynamic adaptation pathway framework to address uncertainties, whereas Saxony in Germany argues that the spread of projections is too large to derive design values and emphasizes the need for standardized scenarios and methods. In summary, our synthesis highlights substantial gaps in climate‐proofing flood risk management and significant regional variation in approaches. Enhanced and faster cross‐border learning could improve the effectiveness of climate‐informed flood risk management.

Understanding vulnerability to flood-induced disasters: a comprehensive scoping review on at-risk individuals and evacuation challenges - Del Prete, Clara; Valente, Martina; Mitiku Saji, Abesha; Khorram-Manesh, Amir; Ragazzoni, Luca (BMC Health Services Research, 2025)
Abstract Flood-induced disasters are increasing in frequency and severity, with high-income countries (HICs) facing growing health, social, and operational challenges, particularly in managing and protecting vulnerable populations that are disproportionately affected. This scoping review, conducted in accordance with PRISMA-ScR guidelines, examined how vulnerability is defined, addressed, and operationalized in evacuation management during flood-induced disasters in HICs. A systematic search identified 98 peer-reviewed studies published between 2014 and 2025. The analysis revealed critical gaps and inconsistencies in how vulnerability is conceptualized and applied in evacuation contexts. Several groups–including single-parent households, caregivers, individuals with mental health conditions, undocumented workers, and those facing linguistic or educational barriers–remain underrepresented, while others, such as informal caregivers, religious minorities, and victims of domestic abuse, are not addressed at all. The review also identified substantial variation in national approaches to vulnerability mapping and management, with most countries relying on fragmented and inconsistently integrated practices. Evidence linking vulnerability assessment to evacuation planning and sheltering decisions remains limited. Research on Flexible Surge Capacity and the use of Alternative Care Facilities for vulnerability-informed evacuation remains scarce, particularly regarding non-medical facilities as community-based hubs for rapid assessment and triage. Furthermore, few studies addressed continuity across the disaster timeline, linking pre-disaster vulnerability assessment, rapid needs assessment, and long-term recovery support. This review advances understanding of how vulnerability can be more effectively embedded in evacuation management, providing empirically grounded and comparative insights to inform inclusive, intersectional, and operational flood-induced disaster management strategies in HICs.

A scenario-based modelling approach to implementing nature-based solutions for flood risk mitigation in Hannover - Schröder, Paula Therese; Wübbelmann, Thea; Kabisch, Nadja (npj Urban Sustainability, 2025)
Abstract The EU Nature Restoration Regulation suggests the implementation of green space as nature-based solutions to enhance urban resilience toward increasing climate risks such as extreme precipitation events and floods in Europe. Scenario based approaches enable the evaluation of the potential of specific nature-based solutions to mitigate flood risk in high flood hazard and vulnerable areas. In this study, we explore the flood risks from heavy rainfall and the potential of nature-based solutions implementations in the city of Hannover, Germany. Using the InVEST urban flood risk mitigation model, we modelled the surface runoff from heavy rainfall and assessed the social vulnerability using population and infrastructure data resulting in a flood risk evaluation. To test flood mitigation under nature-based solutions implementations including grass grid pavers and green roofs, we estimated the runoff improvement under three nature-based solutions scenarios following recommendations from the EU Nature Restoration Regulation. Our analysis revealed that Hannover’s inner-city area is particularly flood-prone and socially vulnerable, while peripheral districts are less affected. The combined risk and vulnerability arise from the surface sealing in built-up areas and their higher population density and associated infrastructure. The scenario results demonstrate flood risk reduction potential when combining different nature-based solutions, though on a limited level calling for more explicit and ambitious regulations at EU, regional and local levels.

Why forests can mitigate floods of all sizes: Evaluating the scientific basis for forest-based flood mitigation - Kaluarachchi, Samadhee; Alila, Younes (Ambio, 2026)
Abstract Rising flood frequencies and magnitudes are causing the loss of lives, infrastructure damage, and economic disruption, making effective flood management imperative. Nature-based solutions are increasingly promoted, but whether forests mitigate large floods remains a decades-long scientific controversy. Resolving this issue is crucial, as flood management necessitates reliable projections and a sound, scientifically defensible understanding. We show that the conventional deterministic approach uses a non-relevant research question, improper hypothesis, and non-causal experiment, rendering its conclusion that forests have little impact on large floods scientifically indefensible. In contrast, a causal, stochastic approach captures the probabilistic nature of floods and allows for studying anthropogenic effects to hydroclimatic variables through its relevant research questions, falsifiable hypotheses, controlled experiment, and sound physical reasoning. The defensible stochastic approach must replace flawed alternatives, suggesting that forests can mitigate large floods. With rigorous methods, hydrology can support strategies which meaningfully reduce flood risk in an increasingly uncertain future.

A new approach to enhance geospatial data selection in geoportals. application for supporting natural hazard early warning system in Nunavik, Québec - Vahdat, Amirhossein (2025)
Malgré la disponibilité croissante de données géospatiales, en particulier au travers de géoportails, la capacité pour un utilisateur de retrouver et de sélectionner les jeux de données géospatiales qui répondront adéquatement à ses besoins reste un défi important. Le projet QAUJIKAIRIT (« alerte » en inuktitut), fondé par Sentinelle Nord et dirigé par le Centre de recherche en données et intelligence géospatiales (CRDIG) et le Centre d'études nordiques (CEN), est confronté à un tel défi. Ce projet vise à établir un système d'alerte précoce robuste pour les risques naturels au Nunavik. Le rôle essentiel des données géospatiales dans la diffusion d'alertes précoces efficaces et en temps opportun est bien connu. Toutefois, les géoportails traditionnels ne parviennent souvent pas à répondre aux besoins divers et changeants des utilisateurs en matière de données, ce qui souligne la nécessité de réfléchir à une approche plus avancée pour la découverte efficace des données géospatiales. Pour répondre à ce besoin, l'objectif principal de cette thèse est **d'améliorer la découverte, le classement et la suggestion de données géospatiales disponibles sur des geoportails Web** connus. À cette fin, la recherche présente **l'approche GeoFit**, qui repose sur deux phases soit un système d'appui à la découverte basé sur des ontologies et un système de recommandation par filtrage collaboratif. Les ontologies permettent d'améliorer la découverte de données en alignant les résultats de recherche sur l'intention de l'utilisateur et la pertinence thématique, tandis que le système de recommandation fournit des suggestions personnalisées de jeux de données basées sur l'historicité du comportement des utilisateurs précédents (à la manière des boutiques en ligne). Ces phases ont été validées par le développement d'un prototype qui recréé un géoportail et testées dans de multiples scénarios, notamment un système d'alerte précoce en cas de crue de rivière au Nunavik. Les résultats de cette recherche sont les suivants: 1) une **ontologie des métadonnées géospatiales** (OMG) qui introduit une représentation uniforme des ensembles de données, permettant un raisonnement sémantique et des classifications thématiques hiérarchiques, 2) un **cadre de découverte des données basé sur l'ontologie** qui intègre l'OMG dans le processus de découverte, fournissant des ensembles de données classés et des capacités de recherche affinées au sein des géoportails, 3) un **système de recommandation géospatiale sémantique** qui améliore les recommandations grâce au filtrage collaboratif basé sur le comportement des utilisateurs, au regroupement sémantique et à l'extraction de règles d'association, en tenant compte de l'extensibilité et de la rareté tout en offrant des suggestions contextuelles pertinentes, enfin, 4) une **ontologie adaptée aux systèmes d'alerte précoce aux risques naturels**, qui organise les données géospatiales essentielles pour les systèmes d'alerte précoce aux risques naturels, en réduisant la nécessité d'une connaissance approfondie du domaine et en fournissant un accès rapide aux ensembles de données pertinents.

Analyse de la connectivité hydrologique du complexe de tourbières du Lac-à-la-Tortue par bilan hydrique - Leblond Chouinard, Jean-Benoît (2025)
Les tourbières sont des écosystèmes représentant une composante majeure du paysage boréal québécois. À l'instar de bien d'autres milieux humides, on leur attribue des propriétés hydrologiques dont les populations pourraient bénéficier dans la lutte aux effets néfastes des changements climatiques, dont certains effets d'atténuation des inondations. Les données ne s'entendent toutefois pas pour bien expliquer les services hydrologiques de ce type. Dans un probable scénario d'augmentation de ces événements extrêmes causés par les changements climatiques, il y a un besoin de mieux comprendre quels effets ont les tourbières sur ceux-ci. C'est dans ce contexte que la connectivité entre les eaux de surface et deux sous bassins versants des tourbières du complexe de tourbières du Lac-à-la-Tortue a été étudiée sur une période de deux ans. La quantification des variations spatiales et temporelles de cette connectivité a été accomplie à l'aide de bilans hydriques sur des périodes multijournalières, mensuelles et saisonnières. Ce projet a également permis de mettre en application la méthode de fluctuation de nappe phréatique afin de quantifier la porosité efficace de la tourbe de façon peu laborieuse et non invasive. Les résultats des bilans ont révélé que la connectivité entre les tourbières et les eaux de surfaces est hautement variable en fonction des contextes initiaux. C'est-à-dire que de fortes précipitations peuvent n'avoir que peu d'impact sur les débits aux exutoires en conditions sèches tandis que de faibles précipitations sont associées à de grandes augmentations des débits en conditions humides. Des relations non linéaires entre les profondeurs de nappes et les débits aux exutoires ont également été observées, permettant de mieux comprendre les seuils qui délimitent ces deux comportements hydrologiques. Ces valeurs constituent des éléments clés dans la compréhension des services d'atténuation des inondations, mais nécessitent toutefois d'être peaufinés. La quantification des débits aux exutoires a représenté un défi technique majeur de ce projet et les courbes de tarages qui en sont issus nécessitent d'assumer qu'il existe une grande marge d'erreur dans les résultats des bilans hydriques. Enfin, ce type de suivi requiert d'être prolongé sur plusieurs saisons afin de prendre en compte l'ensemble des conditions possibles et ainsi de mieux comprendre l'hydrologie complexe de ces écosystèmes.

Contribution de la mission SWOT pour le suivi des étendues et niveaux d’eau dans les milieux humides boréaux - Desrochers, Nicolas (Université de Sherbrooke, 2023)
Il est estimé que les milieux humides constituent entre 5% à 8% du couvert terrestre. Ceux-ci sont d’une importance particulière puisqu’ils remplissent de nombreuses fonctions essentielles à la santé et prospérité de plusieurs espèces vivantes. Cependant, il est estimé que les milieux humides ont globalement perdu environ 21% de leur superficie depuis le début des années 1700. De nombreux efforts ont depuis été mis en place pour réduire et remédier à cette perte. Une saine gestion des milieux humides utilise donc plusieurs méthodes de surveillance, particulièrement pour les fluctuations des niveaux et étendues d’eau. La télédétection offre un grand éventail d’outils pour la détection des eaux en milieu humide. Les données optiques et radars à synthèse d’ouverture (RSO) permettent la délimitation des étendues d’eau et les missions altimétriques mesurent l’élévation de l’eau de façon relativement précise, mais avec une couverture spatiale limitée. La mission Surface Water and Ocean Topography (SWOT) regroupe ces deux types de mesures sous une seule mission et procurera des données d’élévation spatialisées pour plus de 90% de la Terre. Cette thèse porte sur le potentiel et les enjeux que SWOT pourrait rencontrer pour la détection des plans d’eau dans les milieux humides boréaux. Les objectifs principaux sont, d’abord, d’évaluer de multiples missions satellitaires pour la détection d’un évènement d’inondation extrême en milieu humide boréal afin de dégager le potentiel de SWOT et ensuite d’analyser l’impact de la végétation sur la capacité de SWOT à détecter les plans d’eaux. Brièvement, les simulateurs SWOT large échelle (SWOT-LS) et SWOT haute résolution (SWOT-HR) ont été utilisés pour simuler des données SWOT afin de répondre aux objectifs de recherche. D’abord, l’été 2020 a vu l’un des plus importants évènements d’inondations sur le delta des rivières de la Paix et Athabasca (PAD) depuis l’inondation de 1935. C’est une excellente opportunité d’évaluer la capacité d’une multitude de missions satellitaires ainsi que celle du satellite SWOT pour le suivi d’un tel évènement en milieux humides. Le chapitre 4, présenté sous la forme d’un article scientifique, se concentre donc sur l’utilisation de SWOT-LS pour simuler une série temporelle de données SWOT durant un épisode d’inondation extrême sur le PAD à l’été 2020. La détection de l’évolution des étendues d’eau est aussi évaluée pour les missions Sentinel-1, Sentinel-2, Landsat-8 et RADARSAT Constellation tandis que les niveaux d’eau sont évalués pour les missions Sentinel-3 et Jason-3. Ensuite, le chapitre 5, aussi présenté sous la forme d’un article scientifique, évalue l’impact de la végétation aquatique et émergente sur le signal SWOT à l’aide de SWOT-HR. Des données de coefficent de rétrodiffusion provenant de la mission AirSWOT lors d’un survol au-dessus du PAD en 2017 ont été utilisées comme données d’entrée afin d’avoir une meilleure représentation des valeurs attendues du signal SWOT dans un tel environnement. L’ensemble de ces résultats permet de brosser un portrait du potentiel et des enjeux du satellite SWOT pour la détection des plans d’eaux en milieux humides boréaux.

Évaluation de la contamination biologique des surfaces végétalisées (pelouse) par des eaux usées unitaires diluées en temps de pluie et mesures d’atténuation - Souleymane Amadou Maouli, Aboubacar (École de technologie supérieure, 2025)
Avec l’augmentation de la fréquence et de l’intensité des pluies extrêmes, les débordements d’égouts unitaires posent un risque accru pour la santé publique et les biens des citoyens des villes. Les habitants des quartiers voisinant le parc Pierre-Bédard de l’arrondissement Mercier–Hochelaga-Maisonneuve (Ville de Montréal) sont confrontés depuis plusieurs années à des épisodes de débordement. Face à ce constat, les autorités municipales ont entrepris de réaménager le parc Pierre-Bédard afin qu’il puisse recevoir temporairement les excédents d’eaux usées d’égouts unitaires et protéger la population ainsi que leurs habitations. La présente étude, menée sur le site du parc Pierre-Bédard, se veut être un tremplin scientifique permettant de mieux comprendre les risques sanitaires liés à la contamination microbiologique des surfaces végétalisées (pelouse) d’un parc après son inondation par des d’eaux usées unitaires diluées (EUUD) en temps de pluie afin d’orienter les stratégies de gestion et de mitigation post-inondation. Plus spécifiquement, elle visait à caractériser la contamination microbiologique issue de ces EUUD en temps de pluie, à en suivre l’évolution temporelle postinondation tout en la comparant aux niveaux naturellement présents dans les cinq autres parcs urbains (en plus du parc Pierre-Bédard), et à tester des mesures de mitigation pouvant accélérer le retour sécuritaire à l’usage du parc. Structurée en deux phases principales, la démarche reposait sur des séries d’essais de simulation des débordements typiques des EUUD en temps de pluie. La première phase menée d’août à novembre 2023 a permis de concevoir un dispositif pilote simulant une inondation d’une parcelle végétalisée (pelouse), d’élaborer des protocoles d’échantillonnage et de suivi, puis de réaliser des essais exploratoires de suivi temporel de la contamination post-inondation et de mitigation de la contamination (désinfection au chlore et au THYMOX). La seconde phase, menée de juin à octobre 2024, a permis le suivi de la contamination naturelle (sans contamination des pelouses aux EUUD) de six parcs montréalais ainsi que la réalisation de plusieurs essais d’inondation contrôlée (avec suivi temporel de la contamination) et l’évaluation de mesures de mitigation (lavage « hygiénique » initial, lavages à l’eau potable, désinfections au THYMOX et irradiation UV). Les coliformes thermotolérants ont été utilisés comme principal indicateur biologique de contamination lors de la première phase du projet, alors que les organismes Escherichia coli et Clostridium perfringens (fréquence d’analyse moindre) ont été utilisés lors de la seconde phase. Les suivis de la contamination naturelle des parcs montréalais ont permis d’établir des valeurs de référence afin de pouvoir comparer les résultats de contamination de surfaces végétalisées par des EUUD ou encore ceux d’une atténuation naturelle ou provoquée (mesures de mitigation) qui s'ensuit. L’analyse des résultats des parcs a mis en évidence des valeurs de médianes de 21 300 UFC/m² pour E. coli (n = 96) et de 36 100 UFC/m² pour C. perfringens présomptifs (n = 28; avec moyenne géométrique 50 300 UFC/m²). Environ 28 % des échantillons prélevés des surfaces végétalisées des parcs ont dépassé 100 000 UFC/m² en E. coli, avec 8 % des valeurs égales ou supérieures à 1 000 000 UFC/m2. Lors des essais de simulation d’inondations par des EUUD, les surfaces ont atteint des concentrations supérieures aux niveaux de référence des parcs (jusqu’à 1 000 000 UFC/m²). Toutefois, une atténuation naturelle a été observée avec des réductions d’E. coli allant à 2,96 log (99,89 %) en un mois, avec des concentrations inférieures aux références des parcs montréalais dès le 8e jour, particulièrement sous ensoleillement. Le C. perfringens a diminué plus lentement (16 à 30 jours), et les résultats (incluant ceux de E. coli) sont restés marqués par une variabilité et des recontaminations ponctuelles liées à la faune et aux activités humaines. Les désinfections des surfaces contaminées au chlore et au THYMOX ont entraîné des effets négatifs (stress sur la faune et la végétation, recontaminations), tandis que l’irradiation UV n’a pas montré d’efficacité notable par rapport à l’atténuation et l’ensoleillement naturel. Le lavage « hygiénique » initial unique à l’eau potable s’est révélé une mesure efficace (autant qu’un lavage répété ou continu de la surface) réduisant E. coli d’environ 0,87 à 0,90 log (86,5 à 87,4 %; basés sur les moyennes géométriques) dès le premier jour, même si les concentrations résiduelles demeuraient supérieures à la médiane des parcs. Pour C. perfringens présomptifs, les réductions ont été plus modestes (0,44 à 0,52 log, 63,7 à 69,8 %), mais pouvaient atteindre jusqu’à 0,82 log (84,9 %; basés sur les moyennes géométriques) selon la considération des tests de confirmation de l’analyse. Le chlore résiduel de l’eau potable lors d’un lavage n’a montré d’effet bactéricide notable, ce qui confirme que les atténuations post-inondation observées sont dues aux effets de délogement mécaniques des contaminants biologiques lors du lavage « hygiénique » et aux effets naturels qui s'ensuivent, et non à une action chimique. Le « lavage hygiénique » immédiat de la surface contaminée (lorsqu’elle est encore humide) et les mécanismes naturels présents (assèchement et dessiccation, rayonnement UV solaire, sénescence bactérienne et déclin, etc.) lors des jours qui suivent l’inondation par des EUUD ont permis de ramener les niveaux d’E. coli sous le niveau de référence en environ une semaine, et de retrouver des conditions sanitaires en un peu plus deux semaines (cas d’E. coli). Un « lavage hygiénique », complété par un suivi microbiologique lors des premiers évènements, constitue la mesure prioritaire de gestion post-inondation. Par ailleurs, la qualité de la pelouse conditionnerait l’efficacité cette stratégie. Ainsi, une pelouse dense maximiserait ainsi l’effet du lavage « hygiénique », tandis qu’une surface dégradée favoriserait l’atténuation naturelle par exposition solaire.

Impact des débris à flottabilité négative en situation d’inondation côtière extrême - Deschamps, Jaril (Université du Québec, Institut national de la recherche scientifique, 2024)
Les débris impactant des infrastructures critiques sont une cause majeure de destruction lors des événements côtiers extrêmes. Alors que la charge des débris à flottabilité positive (débris ayant une densité inférieure à celle de l'eau) a fait l'objet de nombreuses recherches, à la connaissance de l'auteur, aucune étude n'a porté sur l'impact des débris à flottabilité négative (débris ayant une densité supérieure à celle de l'eau). Pour combler cette lacune, cette thèse de maîtrise présente les résultats d'un programme expérimental portant sur l'impact de débris à flottabilité négative sur une structure en utilisant un mascaret généré par « rupture de barrage ». Des débris sphériques réduits à un rapport de 1 sur 60 ont été entraînés par un mascaret afin d'impacter une structure cylindrique. La vitesse finale des débris à flottabilité négative s'est avérée inférieure à la vitesse du front de l'onde, la vitesse relative diminuant avec l'augmentation de la densité. Le nombre de Stokes des débris s'est avéré être un bon paramètre pour approximer cette vitesse relative. Pour le calcul de la force d'impact, une équation à un degré de liberté basée sur le modèle de rigidité de contact s'est avérée bien adaptée. Toutefois, cette adéquation a été améliorée en incorporant un paramètre supplémentaire dépendant de la densité et du diamètre des débris.

Évaluations actuarielles de différents régimes publics-privés d’assurance inondation - Morin, Gabriel (Université du Québec à Montréal, 2024)
Les inondations constituent le plus important type de désastre naturel au Canada. Toutefois, l’assurance inondation (pour les débordements de cours d’eau) demeure facultative dans le marché privé et, lorsqu’offerte, la prime est souvent inabordable ou la protection insuffisante pour les propriétaires à haut risque. Par conséquent, la plus grande partie du risque d’inondation est assumée par les gouvernements provinciaux et le gouvernement fédéral via les programmes d’aide financière offerts aux sinistrés. Depuis une dizaine d’années, les assureurs et les gouvernements discutent du partage du risque d’inondation au Canada. Suite au rapport du Groupe de travail sur l’assurance contre les inondations et d’aide à la relocalisation déposé en 2022 par Sécurité publique Canada, le gouvernement fédéral a alloué des fonds pour la création d’une société de la Couronne pour faciliter la gestion des impacts financiers des inondations au Canada. Il demeure toutefois qu’un programme d’assurance inondation reste à créer dont les coûts récurrents et non récurrents sont à quantifier. Dans ce mémoire, nous analysons le risque d’inondation au Canada à l’aide d’approches actuarielles et financières pour soutenir le processus décisionnel des gouvernements et des parties prenantes quant au partage des risques financiers des inondations. Selon les données, le risque brut d’inondation au Canada est estimé à 1,4 milliard de dollars en moyenne par année pour 9,8 millions de logements. Les pires risques génèrent une grande proportion du risque total ; leur prime est majoritairement inabordable. En effet, 10% des logements génèrent approximativement 80% des pertes brutes annuelles au Canada. Les coûts annuels moyens d’un programme d’assurance inondation hypothétique couvrant près de 10 millions de logements pourraient varier entre 1,7 milliard et 2,4 milliards de dollars en fonction des protections offertes. Exclure 1% des pires risques diminue fortement les besoins en renflouement du programme d’assurance inondation. Les gouvernements doivent identifier les propriétaires les plus à risque et trouver une solution pour réduire le risque d’inondation au Canada afin d’assurer la viabilité d’un programme national d’assurance inondation. _____________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : évaluation actuarielle, risques financiers, risque d’inondations, assurance inondation, partage du risque

Gestion du risque d’inondations au Québec : vers une contribution accrue des municipalités - Deschamps, Bernard (Université du Québec à Montréal, 2025)
Face au fardeau croissant des inondations fluviales au Québec et aux limites des mécanismes d'indemnisation actuels, cette thèse explore si une participation financière des municipalités à ces mécanismes pourrait les inciter à renforcer leur rôle dans la réduction du risque. L'hypothèse centrale est que l'absence actuelle de cette participation freine les initiatives locales de réduction du risque. La littérature néglige souvent le rôle des municipalités dans ce partage des coûts. Cette recherche comble donc une lacune en examinant l'impact potentiel d'une participation financière sur l'internalisation des coûts du risque et sur le renforcement des incitatifs municipaux en gestion du risque d’inondations. Structurée autour d'un chapitre établissant le cadre conceptuel et de quatre articles de recherche, la thèse analyse d'abord la gouvernance et les failles incitatives des systèmes d'aide post-catastrophes actuels, notamment par une comparaison des modèles du Québec et de la Colombie-Britannique. Elle identifie ensuite les facteurs contributifs aux dommages résidentiels relevant de l'influence municipale, grâce à des entrevues semi-structurées auprès de 45 experts en estimation des dommages. Un modèle innovant de contribution municipale proportionnelle au risque, s'appuyant sur des estimés de dommages basés sur les courbes de submersion-dommages, est ensuite proposé. En dernier lieu, la faisabilité et l'acceptabilité de cette contribution sont évaluées auprès de 35 acteurs et experts du monde municipal québécois. Cette démarche en quatre temps permet une meilleure compréhension des défis liés à la gestion du risque d'inondations par les municipalités québécoises. L'analyse des mécanismes de gouvernance et des systèmes d'aide post-catastrophes discutés au chapitre 2 met en lumière des failles incitatives structurelles qui limitent l'engagement municipal proactif, confirmant la complexité d'une action concertée entre les différents paliers de gouvernement. En identifiant les facteurs contributifs aux dommages résidentiels sous l'influence municipale, le chapitre 3 identifie les leviers d'action potentiels, tout en soulignant les contraintes liées aux aménagements hérités et aux limites perçues du pouvoir municipal. Quant à l'instauration d'une contribution financière directe, le chapitre 5 révèle un scepticisme marqué des municipalités, infirmant en partie l'hypothèse d'un effet incitatif simple. Les préoccupations soulevées, telles que la complexité de mise en oeuvre du modèle proposé au chapitre 4, les contraintes d'aménagement héritées et les limites perçues du pouvoir d'action municipal, convergent vers la nécessité d'explorer des alternatives. Celles-ci pourraient inclure un soutien conditionnel ou des incitatifs non-financiers pour responsabiliser les municipalités sans les pénaliser. Cette thèse contribue ainsi à une compréhension nuancée des leviers d'action pour une gestion municipale plus proactive et durable du risque d'inondations, tout en enrichissant la littérature sur l'efficacité des mécanismes de partage des risques en contexte de changements climatiques. _____________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : inondations, municipalités, gouvernance, facteurs contributifs, incitatifs, partage des coûts

Se raconter pour se rétablir : analyse des processus narratifs soutenant le rétablissement psychosocial des femmes sinistrées par des inondations - Leclerc, Typhaine (Université du Québec à Montréal, 2025)
Cette thèse porte sur les récits de femmes ayant vécu des inondations et sur la manière dont ces récits soutiennent leur rétablissement psychosocial. Les événements météorologiques extrêmes et les désastres qu’ils entrainent provoquent des conséquences psychosociales qui varient en fonction de différents facteurs sociaux, dont le genre. De même, le processus de rétablissement est modulé par ces facteurs et par les ressources matérielles et symboliques auxquelles ont accès les personnes sinistrées, notamment les récits qui donnent du sens à l’expérience vécue. Or, on constate que les narratifs médiatiques et culturels qui circulent au sujet des désastres ne sont pas représentatifs de l’ensemble des expériences de personnes sinistrées : celles qui en subissent les conséquences les plus sévères tendent à être celles qu’on « entend » le moins dans l’espace public. Le besoin de documenter un éventail d’expériences de désastre et de mieux comprendre les processus qui soutiennent le rétablissement psychosocial a guidé le développement de la recherche. Celle-ci est centrée sur les récits faits par les femmes exposées à des inondations en Beauce (Chaudière-Appalaches, Québec) à propos de leur expérience. Elle s’intéresse plus précisément aux histoires racontées par les femmes ayant vécu des inondations et à l’impact de ces récits sur leur reconstruction psychosociale. Le premier volet de la recherche vise à documenter ces récits d’inondation et les processus de rétablissement qu’ils révèlent et repose sur des entretiens semi-directifs réalisés auprès de dix-sept femmes sinistrées. Le second volet a permis d’expérimenter la mise en place d’un espace de prise de parole dédié aux récits de femmes touchées par des inondations par la facilitation d’une démarche de création vidéo selon l’approche du digital storytelling de l’organisme StoryCenter. Les récits des participantes et leur retour sur le digital storytelling ont fait l’objet d’une analyse narrative féministe qui révèle les conséquences multiples des inondations et la manière dont les participantes ont mobilisé différentes ressources pour donner du sens à leur expérience et se rétablir. Les relations de genre dans lesquelles les femmes s’inscrivent, leurs responsabilités familiales, leurs identités, ainsi que d’autres facteurs sociaux entrecroisés, ont influencé leur expérience au moment de l’inondation et dans les années qui ont suivi. La thèse propose une vision du rétablissement psychosocial basée sur une théorisation phénoménologique du chez-soi, considérant la maison comme un lieu de sécurité et de liberté essentiel à qui l’on est, une extension du corps. Parallèlement, le corps est pensé comme une demeure, un chez-soi. Si être en santé permet de se sentir chez soi dans le monde, la maladie et les événements déstabilisants – les désastres, par exemple – bouleversent cette sensation. Le rétablissement est appréhendé ici comme un processus de reconstruction du chez-soi, qui s’est traduit par différents processus de création de sens, soit le fait de documenter son expérience, de s’exprimer à ce sujet, de se comparer et de poser des actions symboliques. L'étude identifie un manque dans la recherche sur les désastres, qui se concentre souvent sur les conséquences de la perte de domicile sans aborder les processus de reconstruction du chez-soi. Le second volet de la recherche a offert aux participantes un espace pour réfléchir à leur vécu d’inondation et pour prendre du recul sur leurs émotions et leur parcours, plusieurs années après l’événement. Le processus de digital storytelling a favorisé des échanges riches entre les participantes et a contribué positivement à leur rétablissement. Cependant, bien que cette méthode ait eu des effets bénéfiques, elle présente des limites, notamment en raison des obstacles logistiques et technologiques rencontrés, ce qui diminue sa transférabilité comme approche d’intervention post-désastre. En somme, cette recherche propose une lecture féministe interdisciplinaire où le récit devient un outil clé pour comprendre la diversité des expériences vécues face aux désastres. Le croisement de la recherche narrative, de l’analyse de genre et d’une perspective critique sur les désastres permet de mieux saisir les enjeux spécifiques des femmes confrontées à des événements météorologiques extrêmes. Les résultats de l'étude soulignent l'importance de prendre en compte une diversité de vécus dans la planification des interventions en matière de gestion des inondations et autres situations de désastre. _____________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : inondations, rétablissement, récits, conséquences psychosociales, genre, femmes, désastres, analyse narrative

Intégration du double drainage et des mesures de contrôle à la source des eaux pluviales dans les secteurs urbains fortement urbanisés. - Ossa Ossa, Juan Esteban (Université du Québec, Institut national de la recherche scientifique, 2024)
Les systèmes d’évacuation des eaux usées et pluviales sont de plus en plus sujets à des surcharges en raison de l’évolution de l’environnement urbain, de la croissance démographique, de l’extension des zones imperméables et des effets des changements climatiques, qui augmentent l’intensité et la fréquence des précipitations. Ces surcharges dans le réseau d’égout posent de multiples problèmes dans les milieux urbanisés. Dans ce contexte, l’objectif principal de cette recherche était d’évaluer différentes alternatives pour atténuer les problèmes de débordement d’égout dans les secteurs fortement urbanisés, en appliquant les concepts du double drainage. Deux objectifs spécifiques ont été poursuivis : le premier visait à développer et à évaluer une méthodologie pour atténuer les problèmes de débordement des réseaux d’égout en mettant en œuvre les principes de double drainage et en explorant des solutions alternatives. Le second objectif visait à analyser les performances hydrauliques et hydrologiques d’une place inondable multifonctionnelle. La méthodologie pour le premier objectif a été appliquée sur deux études de cas, l’une dans l’arrondissement de Rosemont-La Petite-Patrie et l’autre à Saint-Léonard, dans la ville de Montréal, au Canada, connues pour leurs fréquentes surcharges des réseaux d’égout unitaires. Cette méthodologie vise à atténuer ces surcharges et à contrôler les eaux de surface en intégrant des régulateurs de débit d’entrée d’eaux pluviales (ICD) et en adaptant les surfaces urbaines. Ces stratégies ont été mises en œuvre dans un modèle de drainage 1D/2D, ce qui a permis d’estimer qu’elles pourraient réduire les volumes de débordement de surface des réseaux d’égout de 100 % et 86 %, respectivement, dans les deux études de cas, pour une pluie de conception de type Chicago de 3 heures d’une période de retour de 100 ans. Ces stratégies permettraient également de réduire le nombre de débordements de surface de 100 % et 71 %, le volume des inondations pluviales de 78 % et 80 % et leur superficie de 68 % et 42 %, respectivement pour les deux études de cas et pour la même pluie de conception. Pour le deuxième objectif, la performance hydrologique et hydraulique d’une place multifonctionnelle inondable nommée Place des Fleurs-de-Macadam, à Montréal, a été évaluée par un test d’inondation simulant une pluie de période de retour de 100 ans sur 3 heures. Ce site intègre deux types de stratégies de développement à faible impact pour gérer les eaux pluviales: des cellules de biorétention et un bassin de rétention. Les résultats du test d’inondation ont montré que le site est capable de gérer 98 % de l’eau qui tombe sur le site et ses rues adjacentes pour la pluie testée, réduisant ainsi la quantité d’eau dirigée vers le réseau d’égout et contribuant à la réduction des surcharges du réseau d’égout unitaire.

Impacts de l'utilisation de quantités ajustées de précipitations solides dans le système canadien d'analyse des précipitations - Aubry, Catherine (Université du Québec à Montréal, 2024)
Connaître la distribution spatio-temporelle des précipitations en temps quasi réel est essentiel pour diverses raisons, notamment les prévisions météorologiques et d'inondation, la surveillance de la sécheresse, la gestion de l'irrigation, la prévention des incendies de forêt et la production d'hydroélectricité. La gestion de ces activités peut être optimale lorsque les estimations de précipitations disponibles sont fiables. Le système Canadien d’Analyse de Précipitations (CaPA) est un projet développé et coordonné par Environnement et Changement Climatique Canada (ECCC). Ce système d'analyse vise à fournir une estimation des précipitations en temps quasi réel à l'échelle de l'Amérique du Nord. En hiver, la qualité des analyses de CaPA est limitée parce que de nombreuses observations automatiques de surface des précipitations solides ne sont pas assimilées en raison de la sous-captation de la jauge causée par le vent près de la surface. L’efficacité de collecte varie considérablement pour différentes vitesses de vents, pouvant par exemple diminuer son efficacité de collecte de près de 75 % à des vitesses de vents de plus de 7 m s-1. L'objectif de cette étude est d'évaluer la valeur ajoutée de l'ajustement des quantités de précipitations en fonction de la vitesse du vent dans CaPA. Pour ce faire, une nouvelle base de données horaires de précipitations provenant de stations automatiques à travers le Canada est d'abord incluse dans CaPA avec des quantités de précipitations ajustées sur la base de plusieurs types de fonctions de transfert. Dans l'ensemble, les résultats de cette étude suggèrent que l'ajustement des précipitations solides à l'aide d’une fonction de transfert qui dépend de l'intensité des précipitations solides plutôt que de la température de l'air près de la surface est plus susceptible d'améliorer les estimations de précipitations de CaPA pendant la saison hivernale.

Réduire la dépendance aux sacs de sables : pistes d'adaptation durables des maisons riveraines exposées aux inondations au Québec - Kelzi, Joelle (Université du Québec à Montréal, 2025)
Les inondations représentent un enjeu majeur pour les villes riveraines du Québec en raison de leur fréquence croissante, de l’ampleur des dommages causés aux bâtiments résidentiels et des conséquences sur la santé physique et mentale des personnes affectées. Malgré une sensibilisation croissante et des ajustements réglementaires, les mesures mises en oeuvre demeurent souvent temporaires et peu adaptées aux réalités du bâti existant. Le recours systématique aux sacs de sable pour créer des barrières temporaires, bien que largement répandu, illustre les limites des approches actuelles. Face aux défis d'adaptation durable imposés par les changements climatiques, ce mémoire explore des alternatives concrètes pour renforcer la résilience des maisons existantes en zones inondables. S'appuyant sur un état des connaissances en matière de résilience et d’adaptation, la recherche propose un inventaire des dispositifs spécialisés, une présentation de cas d’adaptation à l’international et une analyse critique du contexte résidentiel québécois. À partir de cas réels de maisons riveraines à Montréal, une série de scénarios prospectifs a été développée afin d’illustrer des stratégies durables et applicables à l’échelle du bâtiment et de son entourage. L'objectif est de dépasser les pratiques d'urgence ponctuelles en proposant des mesures de protection plus pérennes, accessibles aux occupants et adaptées aux réalités locales. Ainsi, ce mémoire vise à faire évoluer les pratiques de gestion du risque d'inondation en contexte résidentiel, en encourageant l’émergence de mesures durables et transférables. _____________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : design de l’environnement, inondations, zones inondables, résilience, stratégies d’adaptation, sacs de sable, dispositifs de protection, bâtiments résidentiels riverains, scénarios prospectifs

Inondables ; suivi de Réécrire le vivant - Busque-Dubois, Marilyne (Université du Québec à Montréal, 2025)
Les deux volets de ce mémoire visent à mettre en lumière les potentialités d’une solidarité interespèce et de sa représentation en littérature, dans une lutte contre le système patriarco-colonial et capitaliste. Le volet création est un récit inspiré de l’inondation qui a frappé la région de Charlevoix le 1er mai 2023, suivant une narratrice baie-saint-pauloise sur plus d’un an, des mesures d’urgence à la réintégration de sa maison, en passant par la recherche de refuges temporaires, les travaux de reconstruction et la bataille politique et financière pour la sauvegarde du foyer (intime) et de son patrimoine (collectif). Chaque étape du rétablissement est associée à une stratégie de survie propre à une espèce ou à un groupe d’espèces non-humaine(s) qui habitent aussi les abords de la rivière du Gouffre, qui a aussi dû résister. Ces stratégies non-accessibles aux humain.es (migrer, muer, absorber, flotter, etc.) divisent le texte en autant de chapitres, transportant la narratrice dans des méandres intellectuels et affectifs, souvenirs de survivance, de rencontre avec le vivant, réflexions, doutes, observations, qui lui donnent la force de reprendre, chaque fois, le récit principal, celui de la maison inondée. Le volet réflexif s’attarde à explorer ce qu’une méthodologie de recherche écoféministe appliquée à la création littéraire peut faire survenir tant au niveau des imaginaires qu’au niveau de la forme du texte, dans un contexte de changements climatiques et de montée de l’extrême droite. Il interroge le pouvoir du langage en tant que moyen de résistance à la misogynie et à la biophobie (ou au spécisme) plutôt que comme moyen de perpétuer ses représentations. Par l’incorporation d’une perspective partielle (Haraway), d’une « sublimation qui ne sublime rien » (Bachelard), d’une épistémologie de la désorientation (Ahmed) et de l’incertitude plurielle (Morizot), une poéthique (Andriot-Saillant) se dessine, une écriture qualifiée de biosensorielle, aux confluents de l’expérience vécue (senti), des données scientifiques (appris) et du poétique (imaginé). La réflexion prend la forme de « fiches » inspirées à la fois des fiches espèces des biologistes et des fiches personnages des littéraires, où sont exposés les pistes et obstacles, questions et sensations susceptibles de mener à une représentation plus juste du vivant, c’est-à-dire à un détournement du discours unique et prétendument rationnel qui a engendré et engendre la domination des femmes et de toutes celles et ceux que l’on masse sous une appellation trompeuse, celle du « monde sauvage », ou de « la nature ». _____________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Inondations / Traumatisme dans la littérature / Solidarité dans la littérature / Éthique dans la littérature / Environnement dans la littérature / Crise écologique / Conservation de la biodiversité / Écoféminisme / Récit / Mémoires et thèses de création

Modélisation des crues en régime nival à l'Est du Canada - Yousfi, Nawres (Université du Québec à Montréal, 2024)
Les inondations sont les catastrophes naturelles les plus fréquentes et les plus coûteuses au Canada. Ces événements sont responsables des dégâts majeurs touchant l’infrastructure urbaine, l’environnement, l’écologie, les assurances, l’économie, la santé physique et/ou mentale des citoyens. Ces inondations touchent particulièrement l’est canadien, notamment lors des épisodes de crues printanières. Au Nouveau-Brunswick les principales régions inondables se situent au sein du bassin du fleuve Saint-Jean. Dans ce contexte, il est important de bien comprendre les mécanismes impliqués dans la génération de ces événements hydrométéorologiques extrêmes, afin de mieux les modéliser et en améliorer la prévention. L’objectif principal de cette thèse est de modéliser les crues printanières qui se produisent dans l’est du Canada, et mieux comprendre l’effet de certaines variables météorologiques et climatiques sur les débits printaniers historiques à l’aide des modèles statistiques. Les approches proposées sont illustrées pour une station hydrologique en amont et une autre en aval du bassin du fleuve Saint-Jean. Le premier chapitre présente un état des lieux des connaissances, dans lequel les principaux outils numériques déterministes, utilisés dans la modélisation hydrologique et/ou hydraulique, sont brièvement présentés. De plus, les méthodes probabilistes utilisées comme alternatives aux méthodes déterministes sont également présentées, ainsi que les avantages et limites de chacune des méthodes ou outils. Le chapitre 2 représente l’utilisation du modèle probabiliste Generalized Extreme Value (GEV) dans l’estimation des débits maximums printaniers en fonction des indices météorologiques et climatiques proposés. Les indices sont développés en se basant sur les données historiques brutes et certaines analyses statistiques. La liaison de dépendance entre les variables est représentée par une fonction B-Splines. Le travail a abouti à la rédaction d’un premier article à soumettre dans le Journal of Stochastic Environnemental Research and Risk Assessment (SERRA). Dans le troisième chapitre de cette thèse, un modèle de mélange a été proposé pour améliorer l’estimation des extrêmes de crues à l’aide des données de la station hydrométrique de Fort-Kent. Le modèle développé propose une alternative aux techniques de choix du seuil et combine les distributions de Pareto Généralisée et Gamma. Cette méthode permet de prendre en considération plus qu’un extrême annuel en considérant tous les événements indépendants observés durant la saison à l’étude. Ce travail a fait l’objet d’un article publié dans le Journal of Hydrologic Engineering. Les résultats ont été comparés avec le modèle GEV, utilisé et présenté au chapitre 2, et ont montré une meilleure flexibilité dans la modélisation des séries non stationnaires ou dépendantes. Le modèle de mélange proposé, décrit adéquatement aussi bien la partie centrale, que les deux queues de distribution des débits. En conclusion, ces deux modèles proposés dans cette thèse de doctorat sont flexibles et peuvent être appliqués dans n’importe quel site d’étude, afin de modéliser les débits extrêmes en tenant compte des caractéristiques météorologiques et climatiques propres au site. Le modèle GEV-B-Spline permet d’estimer les débits en fonction de plusieurs covariables explicatives et en se basant sur les débits maximums annuels historiques. Cependant, cette méthode néglige certains événements importants comme les crues en automne. Le modèle de mélange proposée, propose une combinaison de deux distributions pour considérer tous les événements indépendants et enrichir par conséquent la série de données. _____________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Inondation printanière, aléa hydrométéorologique, téleconnexion, modélisation probabiliste, analyse fréquentielle, modèle de mélange, extrême hydrologique

Analyse probabiliste de la formation d’un lac en fosse à ciel ouvert de mine en condition climatique semi-aride et étude des incidences environnementales - Darankoum, Hâdé Jules Wendkouni (Université du Québec en Abitibi-Témiscamingue, 2024)
La création de grands vides résiduels est très courante dans les exploitations minières à ciel ouvert. Ces vides sont parfois abandonnés ou restaurés par inondation. Conformément à des réglementations de plus en plus strictes, les compagnies minières sont tenues de réhabiliter les sites miniers en tenant compte de la préservation de l’environnement et des écosystèmes. La formation de lacs en fosses de mines à ciel ouvert représente une stratégie de restauration fréquemment employée dans l’industrie minière. Cette approche vise à contrôler la génération de drainage minier acide (DMA) en limitant l’exposition des parois rocheuses des fosses à l’oxygène de l’air et au ruissellement, réduisant ainsi l’oxydation des minéraux sulfureux. Ces lacs peuvent également servir de zones pour le dépôt subaquatique des rejets miniers. Dans des conditions appropriées de qualité de l’eau, ils peuvent être exploités en tant que réservoirs d’eau pour divers usages. La viabilité de la formation d’un lacs en fosses de mines à ciel ouvert dépend de plusieurs facteurs, incluant la disponibilité de la ressource en eau, la qualité attendue de l’eau et les possibles impacts sur l’environnement local, tous évalués au préalable. L’étude a porté sur la fosse principale d’une mine située dans la zone sahélienne du Burkina Faso. La région connaît un climat sec marqué par une évapotranspiration élevée avec un rayonnement solaire mensuel moyen de 2060 joules/cm2 et des précipitations d’environ 600 mm/an, caractérisées par des variations spatio-temporelles notables. Les pluies se manifestent principalement sous forme d’orages de fin mai à septembre. Les eaux souterraines, mobilisées par le biais de forages et de puits, jouent un rôle crucial dans la satisfaction des besoins en eau des ménages et du bétail dans la région. Les impacts du rétablissement progressif sur les pentes des parois rocheuses constituent des préoccupations lors de la formation du lacs en fosses de mines à ciel ouvert. L’évaluation de ces impacts a nécessité l’utilisation d’un modèle numérique à éléments finis avec le logiciel ABAQUS. La remontée de la nappe phréatique s’accompagne d’une diminution de la succion matricielle et d’une augmentation progressive des déplacements résultants et horizontaux au fil du temps. Par conséquent, cette dynamique induit une réduction de la résistance au cisaillement de la masse rocheuse in situ, ce qui entraîne des instabilités dans la pente. Aussi la disponibilité de la ressource en eau ainsi que la qualité de l’eau qui s’y formera et d’éventuels impacts sur le milieu environnant ont été évalués. Le processus d’évaluation comprend la construction de modèles d’eau souterraine basés sur trois modèles analytiques, une évaluation du bilan hydrique, et l’utilisation d’un modèle de bilan massique pour évaluer la qualité de l’eau du lac. Pour ces analyses, le logiciel GoldSim a été utilisé pour créer des modèles de simulation de type Monte-Carlo, intégrant des aspects probabilistes. Une analyse de sensibilité a été réalisée, en effectuant plusieurs réalisations avec des paramètres d’entrée stochastiques échantillonnés de manière aléatoire à chaque pas de temps, pour comparer trois modèles d’eau souterraine et évaluer leurs performances. Les mesures d’évaluation comprenaient le coefficient de corrélation (R), le coefficient de détermination (R2), l’écart-type (σ) et la mesure d’importance (p-value). Les modèles de Vandersluis et de Kruseman fournissent des résultats étroitement alignés, affichant des erreurs relatives (ER) comprises entre 0,05% et 0,30%. En revanche, le modèle fondé sur Marinelli et Niccoli présentait des erreurs relatives de 0,31% à 31,75%. Les coefficients de détermination sont respectivement de 0,998, 0,998 et 0,960. Les résultats de l’analyse soulignent la sensibilité de la composante eau souterraine à la fois à la conductivité hydraulique et à la recharge. De plus, l’eau souterraine et les apports de ruissellement ont été identifiés comme les composantes ayant le plus d’impact sur le bilan hydrique du lac, surtout dans le contexte semi-aride du site. Dans des conditions naturelles, l’altitude du lac devrait se stabiliser entre 238 et 242 m, atteignant un équilibre relatif après 160 ans avec 75% de la capacité de stockage de la fosse inexploitée. L’étude indique qu’un lac de type terminal se formerait naturellement, mais la qualité de l’eau se dégraderait au fil du temps. Divers scénarii d’apports d’eau du cours d’eau environnant suggèrent qu’un pompage inférieur à 1,5% du débit, en tenant compte du débit environnemental, serait optimal. Au-delà de cette valeur, plus de 50% des situations probables pourraient entraîner l’infiltration des eaux du lac vers le milieu environnant. Les concentrations prédites de certains paramètres tels que l’arsenic sont significativement plus élevées que les normes, ce qui pourrait empêcher et limiter l’utilisation pour certains usages. Les conditions géologiques, la forte évaporation et la courte saison pluvieuse justifieraient la mauvaise qualité et la dégradation temporelle qui en résulte. Afin d’éviter très souvent la formation d’eau de mauvaise qualité liée au développement d’un lac de mine, l’option combinée du remblayage et de la formation du lac est très souvent recommandée.

Flexibilité métabolomique du saule : De la tolérance au stress salin à la bioraffinerie intégrée avec le traitement des eaux usées - Sas, Eszter (2024)
La transition des activités humaines vers des modèles de développement durable pourrait contribuer à mieux s’adapter aux enjeux mondiaux interconnectés comme les changements climatiques, l’insécurité alimentaire, la santé globale, et l’épuisement des ressources. Cette thèse représente l’un des premiers travaux de recherche visant à combiner l’utilisation des saules à croissance rapide (Salix sp.) pour la phytoremédiation avec leur potentiel pour les bioraffineries. La métabolomique non-ciblée utilisée avec des saules dans deux études complémentaires a permis d’acquérir à la fois des connaissances appliquées sur la valorisation des composés extractibles et une compréhension fondamentale des mécanismes de tolérance au sel. Des saules matures, utilisés pour traiter des eaux usées, ont été évalués à travers un processus de transformation allant de la biomasse brute aux rendements finaux (bioéthanol, lignines, composés bioactifs). L’irrigation avec des eaux usées a triplé les rendements en biomasse, avec une augmentation significative du glucane au détriment d’une réduction des extractibles. Ces variations suggèrent l’allocation des ressources pour soutenir la croissance plutôt que les molécules de défense. Un prétraitement par liquide ionique a fractionné la biomasse, une méthode compatible avec des biomasses contaminées et permettant d’obtenir des composantes séparées de grande qualité. La saccharification enzymatique a livré les rendements en bioéthanol tandis qu’un contre-solvant a précipité la lignine brute, avec une efficacité similaire aux saules témoins. Malgré une teneur réduite en extractibles, l’irrigation par les eaux usées a enrichi le profil phytochimique en flavonoïdes et lignans, potentiellement associés aux perturbations causées par l’inondation et la salinité, et ayant de possibles propriétés antimicrobiennes et antioxydantes. En intégrant deux approches vertes, cette étude démontre une augmentation significative des rendements annuels de bioproduits par unité de surface cultivée, renforçant la viabilité économique et la durabilité environnementale de chacune des deux approches prises individuellement. Une seconde étude s’intéresse plus profondément aux mécanismes de tolérance d’un saule face à deux sels abondants, le NaCl et le Na2SO4, la salinisation étant généralement associée à l’utilisation d’eaux usées et fréquente sur de nombreuses terres marginales. Malgré une conductance stomatique réduite, Salix miyabeana a maintenu sa capacité photosynthétique et sa production de biomasse, même à des niveaux élevés de sel. Les cations et anions salins sont gérés différemment par la plante, qui restreint largement l’absorption du Na+ aux racines, alors que le Cl- et le SO42- sont transportés jusque dans les feuilles. Les analyses révèlent une tolérance résultant à la fois de la plasticité des métabolites constitutifs et des métabolites spécialisés associés aux organes. Les réponses nuancées en fonction des organes et des ions indiquent des adaptations spécifiques dans l’allocation du carbone, la production d’antioxydants ou le métabolisme du soufre par exemple. Seulement 3% des métabolites constituaient une réponse généralisée aux deux types de sels, incluant une réduction de saccharides et un enrichissement de composés phénoliques simples, comparativement aux 28% impliqués au total. Le NaCl induit une réduction du métabolisme énergétique à l’échelle de toute la plante, potentiellement combinée au renforcement racinaire par l’augmentation de précurseurs de la lignine et d’antioxydants. À niveaux équivalents d’électroconductivité et de sodium, Na2SO4 induit une perturbation métabolique plus limitée. Même à concentration double de Na2SO4, l’activité métabolique se caractérise par un enrichissement préférentiel, probablement facilité par l’assimilation de l’excès de SO42- en composés organiques plutôt que leur séquestration. Notre étude des ajustements métaboliques complexes des saules, une espèce non-modèle mais d’importance biologique, environnementale et économique, a contribué à approfondir notre compréhension de leur résilience face aux stress abiotiques, informant ainsi les approches de gestion de l'eau et des terres ainsi que les pratiques de production durables.

Identifying gaps in research on social vulnerability to floods: a systematic review of indicators, indexes, and methodological approaches - Hamidi, Abdur Rahim; Novo, Paula; Paavola, Jouni; Ford, James D (Environmental Research Letters, 2025)
Abstract Social vulnerability plays a critical role in shaping the impacts of flooding, yet the ways in which it is measured remain inconsistent and often disconnected from local realities. As climate-related flood events intensify globally, there is an urgent need to understand how social vulnerability is conceptualized and assessed to inform more equitable and effective risk reduction strategies. This paper reports the results of a systematic literature review on indicators and indexes used to assess social vulnerability to floods. Utilizing the PRISMA methodology, we identified and screened 1621 studies published between 2013 and 2023, selecting 36 peer-reviewed publications for examining how social vulnerability indices have been conceptualized, constructed, and applied, as well as the range of indicators, and methodological approaches used. We identified 78 indicator sets across 22 thematic domains. Results indicate that most attention has been given to a small set of indicators focusing on at-risk populations, socioeconomic factors, housing, and employment, while other factors such as health conditions, disaster preparedness, social connectedness, gender minorities, and sexuality are consistently underrepresented. Many studies rely on established frameworks without adapting them to local socio-cultural contexts and use census and secondary data sources, providing limited household-level and qualitative insights. Lack of methodological transparency, particularly regarding normalization and weighting, is common as is insufficient validation and ground-truthing. Greater attention to these issues, along with empirical case studies, is needed to provide in-depth insights into the root causes of social vulnerability and inform policies better tailored to local realities. This review highlights significant conceptual and methodological gaps, calling for more context-sensitive, mixed-method, and empirically validated approaches to improve the robustness and local relevance of social vulnerability assessments in flood-prone areas.

Polycyclic aromatic hydrocarbon removal from stormwater runoff by bioretention cells: a review - Zhang, Yichi; Xiong, Jiaqing; Zhou, Jiajia; Liu, Yanzheng; Zhang, Qionghua (Environmental Science: Processes & Impacts, 2026)
Polycyclic aromatic hydrocarbons (PAHs) emitted from sources such as industrial activities and transport emissions are washed into rivers and lakes by rainwater runoff and infiltrate groundwater, causing widespread water pollution. , Polycyclic aromatic hydrocarbons (PAHs) are detrimental to human health and the environment as a hazardous persistent organic pollutant of environmental concern. Research is emerging on the occurrence, form, migration characteristics and removal of PAHs from runoff stormwater by bioretention cells. This review analyses the sources of PAHs, the characteristics of their concentration distribution and their migration pattern in stormwater runoff. The mechanism of PAH removal by bioretention cells, the purification effects of different fillers and their influencing factors, and the accumulation characteristics of PAHs in bioretention cells are analysed, and the influence mechanism of PAH accumulation on the performance of bioretention cells is summarised. It is noteworthy that the typical concentration range of polycyclic aromatic hydrocarbons (PAHs) in urban stormwater runoff is 0.65–13.4 µg L −1 . The average PAH concentrations in surface runoff vary across different functional zones, with levels in industrial and commercial areas generally being significantly higher than those in residential areas, green spaces, and other functional zones. Studies have shown that the overall removal efficiency of PAHs by bioretention cells can consistently exceed 80%, demonstrating their significant potential for pollution control. Based on existing research progress, this review further proposes that future efforts should focus on the following research directions: (1) induction of the decomposition of PAHs accumulated in bioretention cells into degradable products; (2) search for more effective fillers to improve their removal efficiency; (3) effects of PAH contamination on microbial functions in the filler of bioretention cells; and (4) synergistic effects of PAHs with other pollutants on bioretention cells. This review evaluates the actual PAH removal performance of bioretention facilities, which holds significant scientific and practical value for optimizing the design of low-impact development facilities and ensuring the safety of the urban water environment.

Systematic Review for Urban Flood Disaster in Managerial Perspective: Forecasting, Assessment and Optimization - Tang, Xuan; Du, Juan; Zhou, Hao; Hu, Zeqian; Liu, Bing; Hu, Min (Sustainability, 2026)
Urban flood disaster management is an interdisciplinary field that integrates hydrology, geology, engineering, and urban planning, with prediction, assessment, and optimization serving as its core components. However, a comprehensive and systematic synthesis of recent developments in this domain remains limited, constraining both theoretical understanding and practical advancement. To address this gap, this study conducts an in-depth analysis of urban flood management research as a systematic review, with a particular focus on advances in prediction, assessment, and optimization. Utilizing a multistep holistic review, combining bibliometric and scientometric analysis with structured literature categorization, the research critically examines and synthesizes relevant findings. This study analyzed 166 research papers related to urban flood management within the Web of Science database. Through co-citation and keyword co-occurrence analyses, five dominant research dimensions are identified: physics-based simulation methods, data-driven approaches, risk assessment tasks, optimization strategies, and miscellaneous emerging topics. Based on these insights, we propose a task-oriented framework that systematically integrates prediction, assessment and optimization across the four phases of disaster management: mitigation, prevention, emergency response and recovery. This framework aids scholars and practitioners in understanding and implementing effective techniques and strategies. The study’s findings shed light on key trends and potential future directions, providing a roadmap for further exploration of urban flood management and guiding professionals in related fields.

Nature-Based Solutions for Resilience: A Global Review of Ecosystem Services from Urban Forests and Cover Crops - Ivanova, Anastasia; Randhir, Reena; Randhir, Timothy O. (Diversity, 2026)
Climate change and land-use intensification are speeding up the loss of ecosystem services that support human health, food security, and environmental stability. Vegetative interventions—such as urban forests in cities and cover crops in farming systems—are increasingly seen as nature-based solutions for climate adaptation. However, their benefits are often viewed separately. This review combines 20 years of research to explore how these strategies, together, improve provisioning, regulating, supporting, and cultural ecosystem services across various landscapes. Urban forests help reduce urban heat islands, improve air quality, manage stormwater, and offer cultural and health benefits. Cover crops increase soil fertility, regulate water, support nutrient cycling, and enhance crop yields, with potential for carbon sequestration and biofuel production. We identify opportunities and challenges, highlight barriers to adopting these strategies, and suggest integrated frameworks—including spatial decision-support tools, incentive programs, and education—to encourage broader use. By connecting urban and rural systems, this review underscores vegetation as a versatile tool for resilience, essential for reaching global sustainability goals.

Evaluating the Effectiveness of Environmental Impact Assessment in Flood-Prone Areas: A Systematic Review of Methodologies, Hydrological Integration, and Policy Evolution - Nxumalo, Phumzile Nosipho; Sabela-Rikhotso, Phindile T. Z.; Kibirige, Daniel; Mbatha, Philile; Byaruhanga, Nicholas (Sustainability, 2026)
Environmental Impact Assessments (EIAs) are crucial for mitigating flood risks in vulnerable ecosystems, yet their effective application remains inconsistent. This study synthesises global literature to systematically map EIA methodologies, evaluate the extent of hydrological integration, and analyse the evolution of practices against policy frameworks for flood-prone areas. A scoping review of 144 peer-reviewed articles, conference papers, and one book chapter (2005–2025) was conducted using PRISMA protocols, complemented by bibliometric analysis. Quantitative findings reveal a significant gap where 72% of studies lacked specialised hydrological impact assessments (HIAs), with only 28% incorporating them. Post-2016, advanced tools like GIS, remote sensing, and hydrological modelling were used in less than 32% of studies, revealing reliance on outdated checklist methods. In South Africa, despite wetlands covering 7.7% of its territory, merely 12% of studies applied flood modelling. Furthermore, 40% of EIAs conducted after 2016 excluded climate adaptation strategies, undermining resilience. The literature is geographically skewed, with developed nations dominating publications at a 3:1 ratio over African contributions. The study’s novelty is its systematic global mapping of global EIA practices for flood-prone areas and its proposal for mandatory HIAs, predictive modelling, and strengthened policy enforcement. Practically, these reforms can transform EIAs from reactive compliance tools into proactive instruments for disaster risk reduction and climate resilience, directly supporting Sustainable Development Goals 11 (Sustainable Cities), 13 (Climate Action), and 15 (Life on Land). This is essential for guiding future policy and improving EIA efficacy in the face of rapid urbanisation and climate change.

Flood Risk Communications Through Maps: Challenges, Perception Theories and Approaches - Yousaf, Nimra; Seenath, Avidesh; Speight, Linda (Journal of Flood Risk Management, 2026)
ABSTRACT Flood risk communication is a core component of flood risk management, yet persistent challenges limit its effectiveness in supporting public understanding, preparedness and adaptive behaviour. Here, we examine flood risk maps as communication tools at the interface of scientific modelling, visual design, and human risk perception. Using a narrative and scoping approach, we synthesise conceptual, theoretical and empirical literature, with particular attention to risk perception theory, framing and map design. We show that flood risk maps often fail to communicate effectively due to poor readability, technical language, inconsistent colour conventions and cognitive biases that shape interpretation and response. Although probabilistic flood maps have been developed to better represent spatial variability and uncertainty in flood risk, they are frequently misunderstood without appropriate framing and contextual support. Our review highlights the critical role of framing choices, communication channels and trust in information sources in shaping how flood risk information is interpreted and acted upon. We further show that participatory mapping can enhance local relevance, understanding and trust by incorporating lived experience, but its application is constrained by issues of scalability, institutional capacity and potential bias. We, therefore, argue that flood risk maps are most effective when embedded within broader, multi‐channel communication strategies.

Beyond ‘Business as Usual’: A Research Agenda for the Operationalisation of Nature-Based Solutions in Flood Risk Management in The Netherlands - Harvey, Nicola Ann; Gilissen, Herman Kasper; Van Rijswick, Marleen (Water, 2026)
The Netherlands is widely recognised as the global leader in water management, with its flood risk management (FRM) infrastructure lauded as being of the best in the world. This status notwithstanding, Dutch FRM primarily maintains established infrastructural practices and experimental applications of NBSs remain less frequent than established structural projects. This paper details and examines the challenges associated with the prevailing ‘business-as-usual’ approach to FRM in The Netherlands, in which traditional ‘grey’ infrastructural techniques are prioritised over innovative ‘green’ nature-based solutions (NBSs). In line with emerging international trends, such as the EU Water Resilience Strategy, NBSs are increasingly advocated as a strategic, complementary layer to enhance the resilience of existing safety frameworks rather than a self-evident replacement for them. Contrary to grey infrastructure, NBSs provide a number of environmental and social co-benefits extending beyond their flood and drought protection utility. The literature on NBSs details the design, effectiveness, and positive socio-economic impact of the operationalisation of such projects for FRM. This notwithstanding, the uptake and practical implementation of NBSs have been slow in The Netherlands. From a legal and policy perspective, this has been attributed to a lack of political will and the corresponding failure to include NBSs in long term FRM planning. Given the long planning horizons associated with FRM (50–100 years), the failure to incorporate NBSs can lead to policy lock-in that blocks future adaptations. Against this backdrop, this paper employs a semi-systematic literature review to clarify the obstacles to implementing NBSs in Dutch FRM and sets a research agenda that charts a course to mainstreaming NBSs in Dutch FRM. Seven core focus areas for future research are identified. The paper concludes by drawing on these identified focus areas to construct a research agenda aimed at systematically addressing each barrier to the practical operationalisation of NBSs in Dutch FRM, emphasising a hybrid green–grey approach which may serve to inspire similar research in other jurisdictions.

(Annual Review of Marine Science, 2026)
Built infrastructure, such as seawalls and levees, has long been used to reduce shoreline erosion and protect coastal properties from flood impacts. In contrast, natural and nature-based features (NNBF), including marshes, mangroves, oyster reefs, coral reefs, and seagrasses, offer not only coastal protection but also a range of valuable ecosystem services. There is no clear understanding of the capacity of either natural habitats or NNBF integrated with traditional engineered infrastructure to withstand extreme events, nor are there well-defined breakpoints at which these habitats fail to provide coastal protection. Evaluating existing NNBF strategies using a standardized set of metrics can help to assess their effectiveness to better inform design criteria. This review identifies a selection of NNBF projects with long-term monitoring programs and synthesizes the monitoring data to provide a literature-based performance assessment. It also explores the integration of NNBF with existing gray infrastructure to enhance overall effectiveness.

Can Flash Flood Risk Index Be an Early Warning Signal of Flash Floods in Ungauged Basin? - Guo, Kaihua; Guan, Mingfu; Yin, Jie (Journal of Flood Risk Management, 2026)
ABSTRACT Flash flooding is amongst the most severe natural hazards, causing widespread socioeconomic impacts across both wet regions and drylands. In ungauged mountainous basins, effective risk warning based on hydrodynamic modelling is challenging due to sparse hydrological observations and complex terrain. Rainfall forecasts can enable timely alerts despite the computational demands of modelling, but their inherent uncertainties further complicate predictions. This study explores the potential of a Flash Flood Risk Index (FFRI), which integrates hydrodynamic simulation outputs with socio‐economic exposure and vulnerability indicators, to provide actionable early risk signal under data‐scarce conditions. The 2022 Datong flash flood in China is used as a case study. Grid‐based hydrodynamic simulations were conducted across varying key parameters and rainfall scenarios to discuss model uncertainty. Model performance was evaluated using UAV‐derived inundation extents, achieving high F1 scores (0.88–0.90), indicating reliable reproduction of flood extents. Simulated water depths and river discharges, however, exhibited substantial discrepancies, particularly in downstream convergence zones, which highlights the critical influence of parameter and rainfall uncertainty on hydrodynamic outputs. The FFRI proposed in the study mitigated these uncertainties, consistently identifying high‐risk areas, especially at the administrative (village) scale across all scenarios. These findings demonstrate that, in data‐limited basins, integrating hydrodynamic modelling with socio‐economic indicators is a practical way to provide actionable risk signal, supporting early‐warning and emergency response where traditional calibration and detailed observations are unavailable.

Building Treatment and Its Effects on City‐Scale Urban Flood Modeling - Li, Zekai; Guo, Kaihua; Duan, Huanfeng; Guan, Mingfu (Journal of Flood Risk Management, 2026)
ABSTRACT Physics‐based flood hydrodynamic models are widely used for predicting inundation in urban basins with complex building layouts. While the treatment of urban buildings in these models has been extensively discussed, over‐assumptions can introduce inaccuracies, uncertainties, and excessive computational effort, particularly under data‐scarce conditions. This study proposes a simple yet effective method, the Building Coverage Ratio (BCR) scheme, to account for building effects in city‐scale urban inundation modeling. The BCR scheme quantifies water abstraction to generate surface runoffs in densely built‐up areas by dynamically adjusting drainage and infiltration volumes based on the proportion of building footprint in each grid cell. This approach improves the accuracy of urban flood predictions when high‐resolution data is unavailable. Validated against a historical rainstorm event in Zhuhai, China, the BCR scheme demonstrated its capability to efficiently and accurately reproduce spatiotemporal inundation patterns. The method significantly improved street‐level flooding simulations, which are often underestimated in traditional approaches that neglect building effects. Results show that simulation accuracy increases from 33% without treatment to over 85% when the BCR scheme was applied to 30 m‐resolution Digital Elevation Model (DEM). As the method relies entirely on open‐source datasets, it offers a practical and transferable solution for urban flood prediction in data‐scarce regions.

Urban growth prediction along Shared Socioeconomic Pathways (SSPs) for future flood exposure risk assessment: a cross-continental analysis of coastal cities - Bachofer, Felix; Wang, Zhiyuan; Huth, Juliane; Eisfelder, Christina; Reimuth, Andrea; Kuenzer, Claudia (Anthropocene Coasts, 2026)
Abstract Climate change remains a defining challenge of the twenty-first century, profoundly impacting ecosystems, economies, and human settlements. Among its consequences, the intensification of flood risks in coastal cities poses a critical threat to sustainable development, particularly in the Global South. This study bridges climate change-induced flooding scenarios with urban growth modelling, integrating Shared Socioeconomic Pathways (SSPs) into the SLEUTH model to simulate future urban trajectories and assess flood exposure under varying climate and socioeconomic conditions. Leveraging Earth observation information products, flood hazard scenarios based on Representative Concentration Pathways (RCPs) and high-resolution (30 m) urban growth projections, this study evaluates coastal, fluvial, and pluvial flood exposure for nine coastal agglomerations with diverse socioeconomic and environmental contexts. Urban growth projections under SSP1/RCP2.6, SSP2/RCP4.5, and SSP5/RCP8.5 scenarios reveal significant variability in urban expansion rates, with four cities projected to expand by over 50% by 2050. Flood exposure assessments for the target year 2050 reveal nuanced spatial and scenario-dependent patterns across all flood types: Surabaya (Indonesia) faces severe coastal flooding (up to 83 km 2 under SSP5/RCP8.5), while Guayaquil (Ecuador) and Ho Chi Minh City (Vietnam) experience extensive risks of fluvial flood exposure, with over 37% of newly developed areas inundated in Guayaquil. Notably, the SSP2/RCP4.5 “Middle of the Road” scenario yields the lowest flood exposure in Khulna (Bangladesh) and Surabaya, whereas SSP1/RCP2.6 and SSP5/RCP8.5 project 30% to over 70% higher exposure in these cities. Disproportionate exposure to inundation in newly urbanized areas, particularly for Dar es Salaam (Tanzania) and Guayaquil, underscores potential risks associated with rapid and uninformed urbanization into flood prone regions. These findings emphasize the dual role of high radiative forcing climate scenarios and socioeconomic pathways in shaping flood exposure and associated risks, advocating for integrated strategies that combine climate mitigation with proactive, scenario-based urban planning.

Detecting Shifts of Monsoon Precipitation Patterns and a Large Increase in Soil Erosion Potential During 1979–2020 in Nepal - Tang, Run; Awasthi, Ram Prasad; Jin, Kailun; Wang, Lang; Liu, Ning; Tiwari, Krishna Raj; Song, Conghe; Amatya, Devendra M.; Sun, Ge; Hao, Lu (Remote Sensing, 2025)
Nepal is highly vulnerable to severe soil erosion driven by monsoonal rainfall and rugged terrains. Limitations in ground observation networks have hindered comprehensive, high-resolution national assessment of precipitation and rainfall-runoff erosivity (R-factor) across Nepal. This study systematically evaluated eight global gridded precipitation datasets (GPDs) against data from 152 weather stations, identifying the optimal precipitation dataset (TPHiPr) representing Nepal’s complex topography. Based on this high-quality dataset, we provided the first independent, long-term (1979–2020), high-resolution national-scale assessment of precipitation and the R-factor for Nepal. Our analysis reveals that 1996 marked a turning point in nationwide precipitation trends: annual precipitation shifted from a decreasing to an increasing one in the humid eastern and central regions, while the drier western region transitioned from an increasing to a decreasing trend, particularly during the dry season. A clear spatial divergence was observed between total precipitation and the R-factor, highlighting the dominant role of precipitation frequency and intensity. Extreme precipitation events intensified significantly (e.g., days with ≥25 mm rainfall increased by 0.2 days yr−1, and the 95th percentile precipitation threshold increased by 0.4 mm yr−1, p < 0.01), driving a nationwide increase in the R-factor (6.3 MJ mm ha−1 h−1 yr−2, p < 0.01), with high-altitude areas experiencing the most pronounced effects. We conclude that soil erosion risk has intensified nationwide due to increasing precipitation extremes. Watershed management must develop elevation-specific adaptation strategies that integrate climate science with practical solutions to address the dual challenges of intensified monsoon-driven erosion and growing dry-season water scarcity.

Beaver dam failures: Reconciling science, perception and policy for sustainable river management in Quebec (Canada) - Biron, Pascale M.; Gauthier, Jean; Dubé, Mathieu; Buffin‐Bélanger, Thomas; Boivin, Maxime (Earth Surface Processes and Landforms, 2025)
Abstract Beavers ( Castor fiber , Castor canadensis ) are recognized as key ecosystem engineers, influencing river hydrology and geomorphology through dam construction. While their structures are associated with positive impacts like flood attenuation, increased biodiversity and water quality improvements, beaver dams are quickly blamed for exacerbating downstream flooding following their failure during extreme rain events. This study examines two Quebec Superior Court rulings (2008 and 2017) where beaver dam failures were considered responsible for significant property damage in the Port‐au‐Persil watershed, located in the Charlevoix region of Quebec, Canada. Using hydrological and hydraulic modelling (HEC‐HMS and HEC‐RAS), we assessed the downstream impacts of beaver dam failures during extreme rainfall events caused by Hurricane Katrina (2005) and Irene (2011). The results reveal that the failure of beaver dams had minimal impact on peak discharge and water levels downstream. For the Irene 2011 event, a 1D hydraulic model showed incremental flow increases of 11–15% and water level rises of up to 0.23 m near the area affected by the damage. A revised 2D model, incorporating a hypothetical four‐fold increase in dam retention volume, demonstrated only minor changes in water levels (0.05 m), confirming that the observed flooding would have occurred even without dam failure. The 2D simulations further highlight that dam height, rather than retention volume, controls downstream flood wave propagation. These findings challenge the negative perception of beaver dams and emphasize the importance of robust scientific assessments in flood‐related liability cases. The legal implications of Article 105 of Quebec's Municipal Powers Act, which holds municipalities liable for flood damage caused by “obstacles” in rivers, create a risk of widespread beaver dam removal. This study advocates for evidence‐based management practices and public education to recognize the ecological benefits of beaver dams while addressing concerns over their perceived flood risks.

Large-Scale Dynamics, Thermodynamics, and Predictability of the 4–25 February 2019 Extreme Precipitation Period in Eastern North America - Low, Yeechian; Gyakum, John R. (Weather and Forecasting, 2026)
Abstract Extreme precipitation is often challenging to predict but can have substantial impacts through flooding and loss of life and property, especially when it is persistent and affects a large region. The 4–25 February 2019 extreme precipitation period in eastern North America (NA) was exceptionally persistent, contributing to extreme winter rainfall and flooding in the Ohio and Tennessee River valleys and unusually heavy snowfall to the north. The period featured anomalous upper-level ridges in eastern NA and the central North Pacific (NP) and an anomalous upper-level trough in western NA, a favorable synoptic configuration for precipitation in eastern NA. The central NP ridge was prominent and extremely persistent, helping to slow and amplify the planetary-scale weather pattern. Within eastern NA, precipitation was lighter, less convective, and more synoptically forced in northern areas, while it was heavier at times and more convective in southern areas. Numerical weather models did not skillfully forecast the weather pattern associated with the onset of the extreme precipitation period beyond a lead time of 7 days, but they were able to more accurately forecast the continuation and persistence of the weather pattern once it started. For this case, simulating the synoptic structure over the NP before the extreme precipitation period accurately is crucial for simulating the later upper-level ridge building in the central NP and resulting downstream weather pattern favorable for persistent precipitation in eastern NA. Significance Statement The 4–25 February 2019 extreme precipitation period was exceptionally persistent, contributing to extreme winter rainfall and flooding in the Ohio and Tennessee River valleys and unusually heavy snowfall to the north, and its onset was not well predicted. The period featured an anomalous, amplified, and persistent large-scale weather pattern favorable for extreme precipitation in eastern North America. Within eastern North America, precipitation was lighter in northern areas, while the precipitation was heavier at times and more convective in southern areas. Weather models’ lack of accurate simulation of the large-scale weather pattern over the North Pacific before the extreme precipitation period was a critical factor in the poor forecasts of the extreme precipitation period’s onset.

Controls on Tributary–Junction Fan Distribution Along the Chaudière River, Québec, Canada - Juneau, Phillipe; Germain, Daniel (Water, 2025)
This study investigates the morphometric and anthropogenic controls governing the occurrence and spatial distribution of tributary–junction fans (TJFs) along the Chaudière River, Québec, Canada. Using GIS-based morphometric analysis, field validation, and multivariate statistics (PCA, CART, LDA), 142 tributary watersheds were analyzed, of which 41 display fan-shaped depositional features. Basin relief, drainage density, contributing area, and slope–area coupling emerge as the dominant predictors of TJF development, delineating an intermediate energy domain where sediment supply and transport capacity become balanced enough to allow partial geomorphic coupling at confluence nodes. CART analysis identified approximate slope and area thresholds (slope < 9°, area > 20 km2; 66% accuracy), while LDA achieved 76%, indicating that morphometry provides useful but incomplete predictive power. These moderate performances reflect the additional influence of event-scale hydrological forcing and unquantified Quaternary substrate heterogeneity typical of postglacial terrain. Beyond morphometry, anthropogenic disturbance exerts a secondary but context-dependent influence, with moderately disturbed watersheds (10–50% altered) showing higher frequencies of fans than both highly engineered (>50%) and minimally disturbed (<10%). This pattern suggests that land-use modification can locally reinforce or offset morphometric predisposition by altering sediment-routing pathways. Overall, TJFs function as localized sediment-storage buffers that may be periodically reactivated during high-magnitude floods. The combined effects of basin geometry, land-use pressures, and hydroclimatic variability explain their spatial distribution. The study provides an indicative, process-informed framework for evaluating sediment connectivity and depositional thresholds in cold-region fluvial systems, with implications for geomorphic interpretation and hazard management.

Scattered seeds, missing garden: a critical review of asset management for nature-based stormwater solutions - Girot, Emma; Tscheikner-Gratl, Franz; Curt, Corinne; Taillandier, Franck; Cherqui, Frédéric (Blue-Green Systems, 2025)
ABSTRACT Nature-based stormwater solutions (NBSSs) have originated as a response to urban drainage challenges, offering today a wide range of co-benefits driven by underlying complex ecological processes. As these systems age, concerns about their effectiveness highlight the need for a comprehensive asset management approach. This study aims to (i) uncover the foundations of NBSS asset management research; (ii) examine its evolution over time, particularly in relation to operation and maintenance; and (iii) identify future research needs within the field. Findings reveal that while the concept of asset management is relatively recent for NBSSs, its individual components have been explored since the 1990s, primarily in North America and Australia. Performance – especially water quantity and quality control – has been the dominant focus, often through experimental studies. In contrast, socio-ecological dimensions remain largely theoretical. Rehabilitation and deterioration have gained traction recently, though not yet as central themes. Maintenance is seldom addressed directly, although it frequently intersects with other asset management aspects. Over the past decade, research interest in NBSS asset management has expanded to more than 30 countries and 38 disciplinary fields. This momentum presents an opportunity to foster interdisciplinary studies that integrate all facets of asset management, in order to support NBSS sustainability.

Failure modes across the life cycle of nature-based stormwater solutions: a systematic review of planning, design, and maintenance challenges - Kaur, Katrin; Annus, Ivar; Caradot, Nicolas; Schütz, Paul; Tarigan, Ari K. M.; Toșa, Cristian; Truu, Murel (Blue-Green Systems, 2025)
ABSTRACT Nature-based solutions (NBSs) are often considered to be cure-all remedies for mitigating risks arising from climate change, among others. This study explores the failure modes of NBSs in stormwater management, and analyses challenges across the different stages of their life cycles, including planning, design, and operation. The PRISMA methodology was applied to carry out a systematic literature review to identify the main triggers, consequences and potential mitigation measures for different failure modes and challenges, with a view to enhancing the long-term performance of NBSs. Each identified failure mode was classified along the three typological dimensions of severity, origin and preventability, with sub-dimensions for qualitative and quantitative analysis. Based on 76 reviewed studies, it was concluded that preventable and intrinsic failures dominate the early stages (planning and design), whereas induced and extrinsic failures tend to manifest during operation and maintenance. The application of interdisciplinary and catchment-scale thinking in planning reduces the probability and severity of failure in the design and operation stages. Standardised and data-based approaches are needed to mitigate NBS failures throughout the life cycle.

(Turkish Journal of Emergency Medicine, 2026)
Abstract Climate change is no longer a distant threat but a present and escalating burden on emergency departments (EDs) worldwide. Its direct and indirect effects, ranging from heatstroke and hypothermia to vector-borne disease resurgence and mass casualty incidents, challenge conventional models of emergency preparedness. This narrative review explores the intersection of climate dynamics with ED operational and clinical vulnerabilities. We summarize five core physiological mechanisms by which temperature extremes disrupt homeostasis and review high-risk medication classes that may exacerbate heat-related morbidity. In addition, we examine the World Health Organization’s mass casualty triage framework and its relevance in climate-driven disasters such as floods, wildfires, and explosions. Special attention is given to low-resource settings and migration-heavy regions, where infrastructure strain and health inequity amplify the impact. We propose integrative, anticipatory planning models that combine clinical vigilance, environmental monitoring, and dynamic triage protocols. By identifying EDs as both front-line responders and sentinel systems, this study underscores the urgency of embedding climate resilience into emergency care strategies. Our synthesis aims to support clinicians, policymakers, and health systems in adapting emergency services to the realities of a warming world.

Vulnerability and Risk Assessment of Sea Level Rise, North Coast, Egypt - Zahra, Khyal A. (World Water Policy, 2026)
ABSTRACT Climate change has a significant impact on the world, primarily through sea level rise (SLR), which causes flooding and erosion in vulnerable, low‐lying coastal areas, such as the Nile Delta. The study utilized the RCP 4.5 and RCP 8.5 scenarios from the Intergovernmental Panel on Climate Change (IPCC) in conjunction with the SimCLIM/Marine Climate Model to project SLR along Egypt's northern coast (ENC). Additionally, a spectral analysis of satellite images from 1985 to 2022 was conducted to assess shoreline erosion and accretion along the ENC. This analysis utilized the Digital Shoreline Analysis System (DSAS) tool and the Modified Normalized Difference Water Index (MNDWI). Estimates of erosion and accretion levels were projected up to 2040. The study identified and forecasted inundated areas for various scenarios from 2020 to 2100 using Geographic Information Systems (GIS) and modified Shuttle Radar Topography Mission (SRTM) digital elevation maps. By 2040, the regions east of the Damietta and Rosetta Nile branches are expected to be vulnerable to issues of erosion and accretion. According to the RCP 4.5 scenario, approximately 30.1 km 2 may be inundated by 2080, whereas the RCP 8.5 scenario predicts an increase to 348.1 km 2 , potentially reaching 738.2 km 2 by 2100. These data indicate that the ENC will become highly vulnerable to climate change under the RCP 8.5 scenario by 2080, whereas the RCP 4.5 scenario is unlikely to impact its current condition significantly. The study recommends implementing integrated measures, such as dikes, to tackle the challenges of low‐lying inundation. This study's findings enhance our understanding of shoreline evolution and refine our ability to predict future changes, enabling policymakers to develop effective policies that protect our marine ecosystem. , 摘要 气候变化对世界产生了重大影响, 其中最主要的是海平面上升 (SLR), 这会导致脆弱的低洼沿海地区 (例如尼罗河三角洲) 发生洪水和侵蚀。本研究利用政府间气候变化专门委员会 (IPCC) 的 RCP 2040 和 RCP 4.5208030.1 情景, 结合 SimCLIM/海洋气候模型, 预测了埃及北部沿海地区的海平面上升情况。此外, 本研究还对 4.5 年至 2022 年的卫星图像进行了光谱分析, 以评估埃及北部沿海地区的海岸线侵蚀和淤积情况。该分析使用了数字海岸线分析系统 (DSAS) 工具和改进的归一化差异水体指数 (MNDWI)。本研究对侵蚀和淤积程度进行了预测, 预测期至 2040 年。研究利用地理信息系统 (GIS) 和改进的航天飞机雷达地形测绘任务 (SRTM) 数字高程图, 识别并预测了 2020 年至 2100 年间不同情景下的淹没区域。到 2040 年, 达米埃塔河和罗塞塔河支流以东的地区预计将面临侵蚀和淤积问题。根据 RCP 4.5 情景, 到 2080 年, 约有 30.1 平方公里的区域可能被淹没；而 RCP 8.5 情景预测, 淹没面积将增加至 348.1 平方公里, 到 2100 年可能达到 738.2 平方公里。这些数据表明, 到 2080 年, 在 RCP 8.5 情景下, 东部尼罗河谷地区将极易受到气候变化的影响, 而 RCP 4.5 情景不太可能对其现状产生显著影响。本研究建议采取综合措施 (例如修建堤坝) 来应对低洼地区被淹没的挑战。研究结果加深了我们对海岸线演变的理解, 并提高了我们预测未来变化的能力, 从而使政策制定者能够制定有效的政策来保护我们的海洋生态系统。 , RESUMEN El cambio climático tiene un impacto significativo en el mundo, principalmente a través del aumento del nivel del mar (ANM), que provoca inundaciones y erosión en zonas costeras bajas y vulnerables, como el delta del Nilo. El estudio utilizó los escenarios RCP 4.5 y RCP 8.5 del Panel Intergubernamental sobre el Cambio Climático (IPCC) junto con el modelo climático marino SimCLIM para proyectar el aumento del nivel del mar a lo largo de la costa norte de Egipto (CNE). Además, se realizó un análisis espectral de imágenes satelitales de 1985 a 2022 para evaluar la erosión y la acreción costera a lo largo de la CNE. Este análisis utilizó la herramienta del Sistema Digital de Análisis de la Línea de Costa (DSAS) y el Índice de Agua de Diferencia Normalizada Modificado (MNDWI). Se proyectaron estimaciones de los niveles de erosión y acreción hasta 2040. El estudio identificó y pronosticó las áreas inundadas para diversos escenarios desde 2020 hasta 2100 utilizando Sistemas de Información Geográfica (SIG) y mapas digitales de elevación de la Misión Topográfica Radar del Transbordador Espacial (SRTM) modificados. Para 2040, se prevé que las regiones al este de los brazos del Nilo de Damietta y Rosetta sean vulnerables a la erosión y la sedimentación. Según el escenario RCP 4.5, aproximadamente 30,1 km 2 podrían estar inundados para 2080, mientras que el escenario RCP 8.5 predice un aumento a 348,1 km 2 , alcanzando potencialmente los 738,2 km 2 para 2100. Estos datos indican que la Costa Este de China (CEC) será altamente vulnerable al cambio climático bajo el escenario RCP 8.5 para 2080, mientras que es improbable que el escenario RCP 4.5 tenga un impacto significativo en su estado actual. El estudio recomienda implementar medidas integradas, como diques, para abordar los desafíos de la inundación en zonas bajas. Los hallazgos de este estudio mejoran nuestra comprensión de la evolución del litoral y perfeccionan nuestra capacidad para predecir cambios futuros, lo que permite a los responsables políticos desarrollar políticas eficaces para la protección de nuestro ecosistema marino.

Lessons from extreme weather events in an intermediate-sized city in Argentina - Lambrecht, Yamila Belén; Picone, Natasha; Zapperi, Paula Andrea (Environmental Research: Climate, 2026)
Abstract This paper examines the impacts of recent extreme weather events in Bahía Blanca, Argentina, within the context of climate change, focusing on the increasing frequency and severity of events affecting urban areas. Using a multidisciplinary approach that combine synoptic and meteorological data, satellite imagery, and fieldwork, the study identifies the atmospheric mechanisms behind each event and their differential effects on the urban environment. The results reveal the severity of a bow–echo windstorm in December 2023, with gusts reaching 155 km h −1 and extensive damage to infrastructure, the local port, and green spaces. An intense heat wave during the 2023–2024 summer and major flooding in March 2025 further exposed critical weaknesses in population preparedness and the limitations of existing drainage infrastructure. These events, occurring within a short period, underscore the urgency of integrating climate risk into urban planning. The study highlights the relevance of real-time monitoring networks, early warning systems, and participatory governance as key tools to enhance resilience and ensure equitable responses to climate-driven extremes.

Mapping Flood Hazard Across Mainland China Through a Physics‐Based Global Flood Model With Embedded Reservoir Operation Scheme - Parmar, Jayesh; Karmakar, Subhankar; Zhang, Cheng; Liu, Yuexiao; Simonovic, Slobodan P. (Journal of Flood Risk Management, 2026)
ABSTRACT China has complex topography, diverse flood mechanisms, and high population exposure, making it highly vulnerable to flooding, highlighting the need for robust national‐scale hazard assessments to identify flood‐prone regions. However, most existing hazard studies are limited to regional scales or rely on empirical indicator‐based methods that overlook flood dynamics. While some global‐scale studies use physics‐based modeling, they offer little insight into China and rarely consider reservoir operations. This study advances national‐scale flood hazard mapping for China using the hydrodynamic Global Flood Model, CaMa‐Flood (v4.2). Simulations driven by ERA5‐Reanalysis runoff showed stronger agreement with observed streamflow than ERA5‐Land. Flood frequency analysis identified the nonparametric Kernel Density Estimator as the most suitable approach. The resulting 0.05° flood hazard maps reveal that nearly half of mainland China faces some level of 1‐in‐100‐year flood hazard, with 26% in the high to very high category. Incorporating reservoir operations reduced the number of national high hazard areas by up to 31%, underscoring their vital role in mitigation. The derived hazard, population exposure, and GDP‐based analysis provide a data‐driven foundation for national and provincial flood risk management, offering a scalable framework for robust hazard assessment and improved exposure and flood risk evaluation.

Geospatial Analysis of Population Exposure to Flooding in the Sudd Region, South Sudan - Chol, Deng Majok; Hall, Jim W.; Wheeler, Kevin G.; Bernhofen, Mark; Di Vittorio, Courtney A.; Strzepek, Kenneth M. (Journal of Flood Risk Management, 2026)
ABSTRACT The Sudd wetland in South Sudan extends over 90,000 km 2 . Large‐scale flood events in recent years (2019–2022) are said to have led to the displacement of an estimated 1.8 million people in total. However, these estimates are approximate and to date there has not been a systematic analysis of population exposure to flooding in the Sudd region. This study seeks to address this gap by using global flood modeling, satellite observations of flood extent, and global gridded population datasets to analyze population exposure. Recognizing the inevitable limitations of these datasets, we intersect all the available global flood mapping and population datasets. The results indicate that 0.8–2.9 million people are currently exposed to the 100‐year return period flood extent, depending on the flood model and population dataset used. Aggregated results of the model agreement intercomparison indicate that all five global models agree on key flood‐prone areas within and around the Sudd, which is further corroborated with satellite flood observations. Intercomparison of the population density among the four georeferenced population products demonstrates that WorldPop and GHSL‐Pop population distributions better represent the patterns of the Sudd rural settlements that are typically in forms of clusters. The uncertainty in exposure estimates is attributable to variations in both flood outlines and geospatial population estimates. These findings provide hitherto unavailable insights into flood exposure in South Sudan, to inform flood management decisions and disaster reduction responses in the Sudd region. This study demonstrates the global significance of model intercomparison as best practice for any flood exposure analysis to underpin policy and decision‐making in Africa and other data‐scarce regions.

Optimizing Flood Hazard Zonation and Planning Landscape‐Based Mitigation Measures in Gimba Sub Watersheds, Northeastern Ethiopia: A Comprehensive Approach - Teku, Degfie; Sisay, Tesfaldet; Ali, Alemnew; Ayalew, Amanuel (Journal of Flood Risk Management, 2026)
ABSTRACT Flooding remains one of the most critical natural hazards threatening livelihoods, infrastructure, and ecological systems in Ethiopia's highland landscapes. This study presents a rigorously integrated, multi‐criteria flood risk assessment that combines the Analytical Hierarchy Process (AHP) with GIS‐based spatial modeling to delineate, classify, and prioritize flood‐prone zones within the Gimba sub‐watershed. Eight biophysical flood‐generating factors stream density, rainfall, slope, elevation, land use/land cover (LULC), soil type, geology, and groundwater depth were systematically evaluated to derive a standardized and weighted Flood Hazard Index (FHI). Standardization was performed through min‐max normalization to ensure comparability across variables, while weighting was achieved using pairwise comparison matrices in AHP, allowing expert judgments to quantify the relative influence of each factor on flood susceptibility. The resulting FHI was subsequently integrated with exposure layers, including population density, built‐up intensity, and road network distribution, to compute a comprehensive Flood Risk Index (FRI). Model accuracy was assessed through spatial overlay with historical flood inventories and Receiver Operating Characteristic (ROC) curve analysis, generating an Area Under the Curve (AUC) value of 0.885, which confirms very strong predictive capability. Results reveal that approximately 34.6% of the Gimba sub‐watershed falls within high or very high flood hazard classes, with pronounced hotspots in downstream floodplains, mid‐slope flash‐flood corridors, and zones undergoing severe land degradation. A targeted mitigation suitability analysis further shows that 32.1% of these high‐risk zones are highly appropriate for nature‐based solutions such as agroforestry, check‐dam installation, terracing, and catchment‐scale reforestation. Importantly, participatory engagement through key informant interviews (KIIs) and focus group discussions (FGDs) played a direct role in refining hazard classifications and prioritizing intervention sites, ensuring that the spatial outputs aligned with community experience, local knowledge, and on‐the‐ground feasibility. This co‐production of knowledge enhanced both the accuracy and social legitimacy of the proposed measures. Overall, the study provides a transparent, adaptable, and policy‐relevant framework for evidence‐based flood risk management. By integrating biophysical hazard metrics, terrain suitability, and stakeholder insights, the approach supports Ethiopia's Climate Resilient Green Economy (CRGE) strategy and national Disaster Risk Management (DRM) initiatives. Moreover, the methodology demonstrates strong scalability and transferability, offering a robust decision‐support tool that can be applied across other data‐scarce, hazard‐prone watersheds to strengthen climate‐resilient landscape planning.

Dynamic Human‐Vehicle Risk Assessment for Urban Flood Evacuations in Island Cities: The MUFE Framework Applied to Haidian Island, Haikou - Bowei, Zeng; Guoru, Huang; Ge, Yang (Journal of Flood Risk Management, 2026)
ABSTRACT Urban flood disasters demand dynamic assessment of population risk, yet most evacuation models fail to capture the multifaceted, time‐varying nature of such events. To address this gap, this study develops the modular urban flood‐evacuation (MUFE) framework, an integrated approach to dynamic urban flood risk assessment. MUFE explicitly models pedestrian and vehicle behaviors under inundation and their interactions with evolving hydrodynamic conditions. The framework is tailored for island cities facing compounded threats from storm surges and sea‐level rise, and is demonstrated on Haidian Island, Haikou, China. The research couples multi‐scenario rainfall‐tide hydrodynamic simulations (via InfoWorks ICM) with an agent‐based model implemented in the open‐source Mesa framework. Mesa enables the explicit representation of pedestrian and vehicle agents operating under perceive‐decide‐act cycles and local information constraints. This integration enables joint analysis of hydrodynamic hazard fields—shaped by dynamic tidal fluctuations—and the behavioral responses of pedestrians and vehicles. The framework is modular, allowing alternative hydrodynamic or data‐driven flood models to be coupled for transparent comparison. Simulation results show that pedestrian hazard exposure varies markedly across space and time, shaped by adaptive evacuation behavior, shelter availability, and tide dynamics. Small vehicles are more susceptible to instability—even under shallow depths—while larger vehicles are more resilient but not immune under severe conditions. These patterns underscore the need for differentiated evacuation planning and targeted infrastructure resilience measures in island cities.

Assessment of Sustainable Urban Drainage Measures for Flood Mitigation in a Densely Populated Watershed in São Paulo, Brazil - Chaves Gonçalves, Filipe; Garcia Bonnecarrère, Joaquin Ignacio (Journal of Flood Risk Management, 2026)
ABSTRACT In light of the increasing adoption of sustainable urban drainage measures for flood control, driven by advances in the urban drainage field and, particularly, in downtown São Paulo, by the significant challenge associated with implementing large detention reservoirs due to the scarcity of open spaces within the watershed, this study investigates the hydrologic and hydraulic parameters that influence the rainfall–runoff simulation in urban areas using the PCSWMM model. Real‐time telemetry data, including measurements from meteorological radar, rainfall gauges, and fluviometric stations, were employed for model calibration and validation. Historical images of São Paulo from the 1930s were used to assess the potential impact of promoting permeable surfaces within the basin on current design hydrographs and flood‐prone area extents. Two future scenarios incorporating sustainable urban drainage strategies for flood mitigation were analyzed to evaluate their effectiveness, complemented by a sensitivity analysis to identify the parameters with the greatest influence on the simulated hydrographs. Results indicate that, even though sustainable measures significantly reduce flood‐prone area extents, their performance is highly dependent on rainfall duration and return period. Consequently, an integrated approach combining conventional and sustainable strategies is recommended for managing design storms with longer durations and higher return periods.

Navigating Water Scarcity for Global Climate Change and Ramifications - Matta, Gagan; Pant, Gaurav; Kumar, Pawan; Pal, Rama (World Water Policy, 2026)
ABSTRACT Climate change has fueled water scarcity creating the most pressing problems of the 21st century, with far‐reaching impacts on ecosystems, public health, and economic stability. Along with physical scarcity of freshwater, insufficient to meet the needs of a population, economic scarcity arises from inadequate infrastructure or poor management of water resources. Either type aggravates the water crisis in regions already prone to geopolitical instability, population pressure, and climate‐induced changes. Extreme weather events, such as floods, droughts, and disruptions to the hydrological cycle caused by climate change, create erratic precipitation patterns and higher evaporation rates, which directly affect water quality and availability. Water stress has a severe impact on the agricultural sector, contributing to crop failures, food insecurity, and increased prices in regions that rely heavily on irrigated land. Wetlands, rivers, and lakes face decreasing water levels, putting the ecosystem services of water purification, flood regulation, and biodiversity maintenance at risk. This leads to a shortage of clean water, which in turn fosters the proliferation of waterborne diseases and poses a significant risk to public health, particularly in underdeveloped areas. The article emphasizes the importance of adopting integrated approaches to water management, sustainable land use, and transboundary cooperation to address the interconnected challenges of water scarcity and minimize their widespread impacts. Climate adaptation measures and innovative irrigation and water conservation systems are needed to guarantee long‐term water security and resilience in vulnerable regions worldwide. , 摘要 气候变化加剧了水资源短缺, 使其成为21世纪最紧迫的问题之一, 对生态系统、公共卫生和经济稳定产生深远影响。除了淡水资源本身的物理匮乏 (不足以满足人口需求)之外, 经济上的短缺还源于基础设施不足或水资源管理不善。这两种情况都会加剧本已易受地缘政治不稳定、人口压力和气候变化影响地区的水危机。极端天气事件, 例如洪水、干旱以及气候变化导致的水文循环紊乱, 造成了降水模式的异常变化和蒸发率的上升, 直接影响水质和水量。水资源压力对农业部门造成严重影响, 导致作物歉收、粮食不安全和价格上涨, 尤其是在严重依赖灌溉土地的地区。湿地、河流和湖泊的水位下降, 使水净化、洪水调节和生物多样性维护等生态系统服务面临风险。这导致清洁水资源短缺, 进而助长水传播疾病的蔓延, 对公众健康构成重大威胁, 尤其是在欠发达地区。本文强调, 必须采取综合方法, 包括水资源管理、可持续土地利用和跨界合作, 以应对水资源短缺带来的相互关联的挑战, 并最大限度地减少其广泛影响。气候适应措施以及创新的灌溉和节水系统对于保障全球脆弱地区的长期用水安全和复原力至关重要。. , RESUMEN El cambio climático ha exacerbado la escasez de agua, creando uno de los problemas más acuciantes del siglo XXI, con profundas repercusiones en los ecosistemas, la salud pública y la estabilidad económica. Además de la escasez física de agua dulce, insuficiente para satisfacer las necesidades de la población, la escasez económica surge de la infraestructura inadecuada o la mala gestión de los recursos hídricos. Ambos tipos de escasez agravan la crisis del agua en regiones ya propensas a la inestabilidad geopolítica, la presión demográfica y los cambios inducidos por el clima. Los fenómenos meteorológicos extremos, como inundaciones, sequías y alteraciones del ciclo hidrológico causadas por el cambio climático, generan patrones de precipitación irregulares y mayores tasas de evaporación, lo que afecta directamente la calidad y la disponibilidad del agua. El estrés hídrico tiene un grave impacto en el sector agrícola, contribuyendo a las malas cosechas, la inseguridad alimentaria y el aumento de precios en las regiones que dependen en gran medida de la tierra de regadío. Los humedales, ríos y lagos se enfrentan a la disminución de sus niveles de agua, lo que pone en riesgo los servicios ecosistémicos de purificación del agua, regulación de inundaciones y mantenimiento de la biodiversidad. Esto conlleva una escasez de agua potable, lo que a su vez fomenta la proliferación de enfermedades transmitidas por el agua y supone un riesgo significativo para la salud pública, especialmente en zonas subdesarrolladas. El artículo subraya la importancia de adoptar enfoques integrados para la gestión del agua, el uso sostenible de la tierra y la cooperación transfronteriza para abordar los desafíos interconectados de la escasez hídrica y minimizar sus impactos generalizados. Se necesitan medidas de adaptación al cambio climático y sistemas innovadores de riego y conservación del agua para garantizar la seguridad hídrica y la resiliencia a largo plazo en las regiones vulnerables de todo el mundo.

The impact of climate change induced extreme weather events on microbial dynamics and public health: an in-depth review on water quality and ecosystem resilience - Huang, Shangshu; Jiang, Fahui; Dong, Qi; Yu, Junfeng; Fan, Ke; Wang, Zhijian; Hao, Shouli; Qiao, Yanjun (Frontiers in Environmental Science, 2025)
Climate change is significantly increasing the frequency and intensity of extreme weather events (EWEs), including severe storms, catastrophic floods, prolonged heatwaves, and extended droughts. These events have significant impacts on hydrological systems, microbial ecosystems, and public health. Therefore, this detailed review was carried out to explore the impact of climate change induced extreme weather events on microbial contamination and public health. The detailed search revealed that EWEs can lead to increased microbial contamination in water sources, potentially causing outbreaks of waterborne diseases. In addition, EWE can also disrupt nutrient cycles and alter microbial community structures, affecting ecosystem stability and resilience. Moreover, EWEs can mobilize pollutants such as microplastics, antibiotic-resistant genes, and PFAS, further degrading water quality. Despite these challenges, microbial communities can play a crucial role in mitigating the impacts of EWEs by degrading pollutants and stabilizing nutrient cycles. In addition, we found that real-time monitoring techniques, such as environmental DNA (eDNA) profiling, can help identify contamination sources and inform targeted interventions. At last, we observed that integrating microbial insights into ecosystem management and public health strategies is essential for developing resilient and adaptive approaches to address the escalating impacts of climate change on water quality and public health. Therefore, this study is particularly important in highlighting its contribution to the development of more effective and resilient management practices in the face of increasing climate variability.

Geospatial Technologies in Crisis Response: Analyzing the 2024 Floods in Valencia, Spain - GIS Laboratory, Escuela Nacional de Estudios Superiores Morelia, Universidad Nacional Autónoma de México, Mexico GIS Laboratory, Escuela Nacional de Estudios Superiores Morelia, Universidad Nacional Autónoma de México, Mexico; Franch-Pardo, Ivan; Fuster Puig, Pau A.; Soil Erosion and Degradation Research Group, Departament de Geografia, Universitat de València, Spain; Cerdà, Artemi; Soil Erosion and Degradation Research Group, Departament de Geografia, Universitat de València, Spain (European Journal of Geography, 2025)
On October 29, 2024, a cut-off low (DANA) caused the most catastrophic flooding in recent history in Spain and the Mediterranean region, in Valencia, resulting in 228 deaths, more than €13 billion in damages, and the disabling of more than 140,000 vehicles. In the days following the disaster, a lack of information and a limited institutional response created a climate of uncertainty. In this context, satellite imagery became the only reliable source of information. This study adopts a systematic review methodology to reconstruct and critically analyze how geospatial technologies were used for forecasting, documenting, and managing the disaster. It draws on a compilation of meteorological datasets, satellite imagery (e.g., Sentinel, Landsat), GIS outputs, institutional maps, and academic research. The research identifies four chronological phases: First, meteorological data were employed to sound the alarm; second, satellite imagery products were used when the dis-aster already occurred; third, development of web platforms with geographic information and other institutional servers for data download; and four, new lines of research with the inputs generated in the previous points. The intervention of international coordination platforms—the Copernicus EMS rapid mapping service and the International Charter: Space and Major Disasters—allowed, in record time, the processing of the first satellite images and the expedited mapping of flooded areas. The findings demonstrate that spatial analysis tools are one of the most important inputs when dealing with a natural disaster, especially in the first hours and days following the event. However, prior territorial planning and the prompt intervention of decision-makers when such an event occurs are the most decisive factors in minimizing damage. The study al-so contrasts climate change-based explanations with historical-geographic interpretations of the disaster, underscoring the need for a comprehensive, geographically grounded approach to future risk management.

Towards a Structured Approach to Advance Sustainable Water Management in Higher Education Institutions: A Review - Boiocchi, Riccardo; Peruzzi, Cosimo; Giurea, Ramona; Rada, Elena Cristina (Water, 2025)
The aim of this paper is to investigate the measures adopted by higher education institutions (HEIs) for sustainable water management in university campuses. Rain and storm water harvesting and treatment, rain and storm water reuse, wastewater treatment and reuse and technologies for runoff reduction were found to be frequently undertaken. Sustainable approaches to water supply such as water-efficient appliances, irrigation algorithms and the use of drought-resistant plants have been adopted as well. In support, monitoring of consumed water and of rain and storm waters has been a widespread practice. Important considerations were given to the impact of the identified measures on campuses’ energy consumption and greenhouse gas emissions. Nature-based solutions, employment of renewable energies and sustainable disinfection methods are measures to prioritize. Some wastewater technologies may deserve priority in virtue of their positive contribution to circular economy. Drawbacks such as groundwater and soil contamination due to wastewater reuse and the release of pollutants from fertilized nature-based technologies were identified. Despite their variety, it must be noted that many of these measures have generally involved rather limited portions of campuses, taken more for demonstration or pilot/full-scale research purposes. Additional measures not identified in the current review—for instance the prevention of pollution from micropollutants and waste mismanagement—should be implemented to boost HEIs’ environmental sustainability. The findings of this review pave the way for a more structured implementation of water sustainability measures in university campuses.

Effectiveness of Interventions to Reduce Carbon‐Emissions Within Secondary Healthcare: Systematic Review and Evidence and Gap Map - Shaw, Liz; Orr, Noreen; Lawal, Hassanat M.; Briscoe, Simon; Yan, Xiaoyu; Coon, Jo Thompson; Melendez‐Torres, G. J.; Martin‐Pintado, Clara; Garside, Ruth (Campbell Systematic Reviews, 2025)
ABSTRACT ‘The climate emergency is also a health emergency’ (England 2024). Climate change directly impacts the health of the human population through events such as earthquakes, flooding, heatwaves and drought, which increase the risk of injury, displacement, disruption of food supplies, infectious diseases and mental ill health (England 2024; Lenzen et al. 2020; Tennison et al. 2021; The Lancet Respiratory Medicine 2023). The impact on population health of these climate events, alongside indirect health consequences such as increased prevalence of respiratory conditions due to air pollution, places an increased burden on health services (Royal College of Physicians 2017). The environmental footprint of healthcare services contributes between 1% and 5% towards total global environmental impacts (Lenzen et al. 2020; Tennison et al. 2021). Reducing the impact of the healthcare system on climate change has the potential to benefit population health through improved air quality and diet, and increased activity levels (Mailloux et al. 2021). Due to the lack of systematic reviews which consider carbon emissions associated with the patient pathway within individual specialities, further research is needed to enable the identification and transformation of the most carbon‐intensive clinical pathways, while ensuring future models of care can be delivered in a cost‐effective manner without increasing emissions or compromising patient care. In 2008, the Climate Change Act set national targets for the 100% reduction of carbon emissions in England to 1990 levels by 2050 (‘Climate Change Act’ 2008). Within the United Kingdom, the National Health Service (NHS) has an important role in helping to achieve these targets, as the organisation accounts for 4% of England's carbon footprint (NHS England 2022). The UK government's Greener NHS team from NHS England asked the Exeter Policy Research Programme Evidence Review Facility to bring together and analyse research which assesses different ways carbon emissions resulting from hospital‐led care can be reduced, without affecting the care patients receive in hospitals, at home and in clinics. Work focusing on identifying and delivering interventions to reduce carbon emissions within known carbon hotspots, such as NHS estates and facilities, travel and transport, supply chain, and certain medicines and medical and anaesthetic gases that have high global warming potential is already underway, alongside examining the effectiveness of different models of care delivery across all specialities (NHS England 2022; NHS Shared Business Services 2022). Evidence focusing on the effectiveness of interventions in reducing carbon emissions within secondary healthcare would be a useful complement to this work. An approach which considers the patient pathway may be beneficial in identifying interventions which consider wider healthcare systems and thus have a meaningful impact on reducing carbon emissions. This review was commissioned by the Greener NHS team and could serve as a useful case study for wider net‐zero ambitions elsewhere in the world. We aimed to carry out a systematic review examining the effectiveness of interventions in reducing the carbon footprint within specific medical specialities in secondary healthcare and explored where this evidence could inform the patient care pathway. In July 2023, we searched a selection of bibliographic databases with coverage of both health care and environmental science journals, including MEDLINE, Embase and Environment Complete, which we supplemented by inspecting the HealthcareLCA database, conducting forwards and backwards citation chasing on all studies which met our inclusion criteria, searching reference lists of topically relevant reviews, and searching Google Scholar and a selection of relevant websites. We included studies using any comparative study design evaluating any intervention intended to reduce the environmental impact of a procedure, process, treatment, or pathway delivered within secondary healthcare in the following specialities: cardiology, gastroenterology, obstetrics, oncology, ophthalmology, orthopaedics and trauma, radiology, renal, respiratory and high volume, low complexity surgeries (specifically: ear, nose, and throat [ENT], gynaecology and urology). We extracted descriptive data regarding study sample, intervention/control group, carbon emission methodology, PROGRESS‐PLUS criteria (related to equity) and environmental, patient and cost outcomes. We appraised the quality of studies using life cycle assessment (LCA) methods with a predetermined scoring system informed by Weidema's (1997) guidelines (B.P.W. 1997). We synthesised findings from studies drawing on LCA methods and non‐LCA studies separately using narrative synthesis. Within each group, studies were clustered into five broad intervention categories: (1) Accessing care, (2) Product level, (3) Care delivery, (4) Setting and (5) Multiple components. We examined and explained patterns across studies within the same speciality which evaluated similar interventions. We also developed an evidence and gap map (EGM) to highlight where evidence relevant to the review aims could inform a generic patient care pathway for each speciality and future research on lower carbon pathways. Input from the Greener NHS team at NHS England, LCA methods experts and patient and public representatives was incorporated throughout. Eighty‐eight studies (92 articles) met eligibility criteria, 28 used LCA‐informed methods to calculate carbon emissions (19 of these utilised a full LCA approach). Of the LCA studies, 9 were of Low risk of bias, 14 of Medium risk of bias and 5 of High risk of bias. Urology ( n = 14), gastroenterology ( n = 13), oncology/radiation oncology ( n = 13) and renal ( n = 11) were the most common specialities represented. Across different specialities, most evidence was found in the first three stages of the patient care pathway (Initial assessment/diagnostic tests, initial treatment, or routine follow‐up). The exception was the renal speciality, where most evidence was within ‘Ongoing care’ segment. There was limited evidence within the ‘Discharge’ segment of the care pathway across all specialities. Evidence relating to the wider healthcare setting was clustered within gastroenterology ( n = 5) and radiology specialities ( n = 5). The two largest groups of evidence were for studies evaluating telehealth ( n = 26) and reuseable equipment ( n = 13) interventions. Telehealth interventions were predominantly evaluated using non‐LCA methods ( n = 23). While carbon‐emissions favoured telemedicine interventions versus face‐to‐face care, these calculations often only considered patient‐travel saved and did not account for carbon emissions associated with other parts of the delivery of the service, such as digital technology used or energy use of building or clinic equipment for face‐to‐face appointments, or wider impact on the patient care pathway such as potential need to travel for additional primary care appointments. The majority of patient and cost outcomes favoured telemedicine interventions, although most were based on non‐statistical analyses. Interventions comparing carbon emissions associated with the use of reuseable versus disposable surgical equipment represented the largest group of studies using LCA methods. For studies within gastroenterology, reuseable equipment was associated with reduced carbon emissions. Within urology, this finding was reversed, although questions regarding the accuracy of use of characterisation factors, quantity of materials used in disposable versus reuseable equipment packs and how carbon emissions were assigned to the reprocessing of reuseable equipment mean confidence in this finding is uncertain. While waste management/reduction interventions were associated with reduced carbon emissions, interventions were highly heterogeneous, with limited consideration of patient or cost outcomes. Eight non‐LCA studies found that reduced carbon emissions were associated with energy conservation interventions, such as turning equipment off when not in use or choosing imaging techniques with lower energy use, the majority of which were conducted within radiology/radiotherapy settings. This systematic review synthesises quantitative evidence evaluating the effectiveness of interventions intended to reduce carbon emissions within high‐volume secondary healthcare specialities. It highlights a highly heterogeneous evidence base, and the methodological limitations associated with studies based on LCA and non‐LCA methods. While we identified several large clusters of studies evaluating similar interventions within the same speciality, future research needs to address these methodological limitations to support confident decision‐making within policy commissioning and clinical practice. Our EGM displays the included evidence according to individual speciality along the patient pathway, enabling evidence users to identify research which meets their requirements as well as identifying potential gaps where further research may be required.

Bridging the Scaling Gap: A Review of Nonlinear Paradigms for the Estimation and Understanding of Extreme Rainfall from Heavy Storms - Cheung, Kevin K. W. (Fractal and Fractional, 2025)
Short-duration extreme rainfall is a major trigger of flash floods and urban inundation, yet its quantification remains a profound challenge due to the scarcity of high-resolution observations. This review synthesizes how three central paradigms of nonlinear science, multifractal cascade theory, self-organized criticality (SOC) and chaos theory, provide critical insights and practical methodologies for bridging this observational gap. We examine how multifractal temporal downscaling leverages scale-invariance to derive sub-hourly rainfall statistics from coarser data. The SOC paradigm is discussed for its ability to explain the power-law statistics of rainfall extremes and cluster properties, offering a physical basis for estimating rare events. The role of chaos theory and its modern evolution into complex network analysis is explored for diagnosing predictability and spatiotemporal organization. By comparing and integrating these perspectives plus recent developments in stochastic hydrology, this review highlights their collective potential to advance the estimation, understanding, and prediction of short-duration extreme rainfall, ultimately informing improved risk assessment and climate resilience strategies.

Tsunami Early Warning Systems: Enhancing Coastal Resilience Through Integrated Risk Management - Perez-Rodriguez, F.-Javier; Otero-Mateo, Manuel; Batista, Moises; Ramirez-Peña, Magdalena (Water, 2025)
Tsunamis are among the most destructive natural hazards, posing severe risks to coastal communities and infrastructure. Effective flood risk management (FRM) for these extreme events requires robust and well-integrated early warning systems (TEWSs). This paper explores the fundamental principles and technologies underlying tsunami TEWS, emphasizing their critical role within the broader context of FRM. It examines how modern systems integrate seismic sensor networks, wave detection buoys, and satellite monitoring to provide rapid and accurate alerts. Technical and logistical challenges are discussed, including the need for precise propagation models and real-time data integration to minimize false alarms and improve system efficiency. Case studies, such as the Pacific Tsunami Warning System (PTWS) and the Indian Ocean Tsunami Warning System (IOTWS), are presented to evaluate lessons learned and areas for improvement. Finally, this paper argues that to be truly effective, TEWS must be complemented by coastal resilience strategies, community engagement, and strong public policies that promote preparedness and adaptation to future events. This comprehensive approach not only enhances response capabilities but also significantly reduces the risk of human and economic losses in the world’s most vulnerable regions.

Health equity in the wake of disasters and extreme weather: evidence from an umbrella review - Stimpson, Jim P; Rashed, Amir L; Pandya, Jay; Baudot, Emily C; Whitfill, Jill; Ortega, Alexander N (Health Affairs Scholar, 2025)
Abstract Introduction Natural disasters and climate-related extreme weather events are increasing in frequency and severity, magnifying health inequities and exposing systemic weaknesses in health and social infrastructure. Methods This umbrella review synthesized findings from 33 systematic reviews and meta-analyses published between 2005 and 2025 to assess the physical or mental health outcomes or healthcare access impacts of disasters on populations experiencing health disparities. Results Mental health effects, especially post-traumatic stress, depression, and anxiety, were consistently elevated across disaster types. Geophysical events such as earthquakes and tsunamis produced sustained psychological distress and service disruptions among displaced and low-income populations. Hydrological and meteorological disasters, including floods and hurricanes, increased infectious-disease incidence and maternal and geriatric morbidity. Climatological hazards such as heatwaves, droughts, and wildfires were associated with cardiovascular, respiratory, and metabolic impacts, particularly among older adults and outdoor workers. Reviews addressing multiple hazards emphasized persistent inequities in healthcare access and long-term recovery. Few studies analyzed intersectional determinants, limiting understanding of compounding risk. Conclusion Policy responses should embed social vulnerability assessments into preparedness and recovery planning, invest in behavioral health and primary care surge capacity, and ensure income, housing, and transportation supports for disproportionately affected communities.

Seven Decades of River Change: Sediment Dynamics in the Diable River, Quebec - Faghfouri, Ali; Germain, Daniel; Fortin, Guillaume (Geosciences, 2025)
This study reconstructs seven decades (1949–2019) of morphodynamic changes and sediment dynamics in the Diable River (Québec, Canada) using nine series of aerial photographs, a high-resolution LiDAR Digital Elevation Model (2021), and grain-size analysis. The objectives were to document long-term river evolution, quantify erosion and deposition, and evaluate sediment connectivity between eroding sandy bluffs and depositional zones. Planform analysis and sediment budgets derived from DEMs of Difference (DoD) reveal an oscillatory trajectory characterized by alternating phases of sediment export and temporary stabilization, rather than a simple trend of degradation or aggradation. The most dynamic interval (1980–2001) was marked by widespread meander migration and the largest net export (−142.5 m3/km/year), whereas the 2001–2007 interval showed net storage (+70.8 m3/km/year) and short-term geomorphic recovery. More recent floods (2017, 2019; 20–50-year return periods) induced localized but persistent sediment loss, underlining the structuring role of extreme events. Grain-size results indicate partial connectivity: coarse fractions tend to remain in local depositional features, while finer sediments are preferentially exported downstream. These findings emphasize the geomorphic value of temporary sediment sinks (bars, beaches) and highlight the need for adaptive river management strategies that integrate sediment budgets and local knowledge into floodplain governance.

Estimating the Impact of Impounding an 85‐km^2 Hydropower Reservoir in a Subarctic Environment on the Local Radiation Balance - Ben Aba, Imen; Nadeau, Daniel F.; Sylvain, Jean‐Daniel; Drolet, Guillaume; Anctil, François (Journal of Geophysical Research: Atmospheres, 2025)
Abstract This study focuses on the net radiative forcing caused by the impoundment of an 85‐km 2 hydroelectric reservoir in the subarctic Côte‐Nord, Quebec, Canada (50.69°N, 63.24°W, mean depth of 44 m). Using spectral bands from the Landsat 7 ETM+ and Landsat 8 OLI/TIRS satellites, we observed spatial and temporal variations in albedo and surface temperature on 104 dates between 2000 and 2023. By integrating these data with ERA5‐Land meteorological reanalyses and in situ measurements, we investigated seasonal and interannual variations in shortwave and longwave radiative fluxes and net radiation before (2000–2013) and after (2015–2023) reservoir impoundment. The flooded area initially consisted of 79% coniferous forest (mainly black spruce), 15% water, 4% dry soil, and 2% wet soil. Before the impoundment, the average winter albedo was 0.25 ± 0.02 and the summer albedo was 0.08 ± 0.002. After the impoundment, the winter albedo increased significantly, reaching between 0.70 and 0.90 in the presence of fresh snow on the ice (January to May), while in summer it decreased to about 0.05 ± 0.003. Surface temperatures exhibited pronounced pre‐ to postimpoundment contrasts, with the reservoir consistently 2–7°C warmer in autumn and winter but 1–5°C cooler in spring and summer. The reservoir also reaches its maximum temperature 3–5 weeks later. The impoundment induced a net radiative cooling of −21 W m −2 compared to forest, featuring a pronounced winter deficit (−60 to −140 W m −2 ) due to snow cover albedo effects, partially compensated by summer surpluses (+5 to +50 W m −2 ). , Plain Language Summary Hydropower is a strategic solution for reducing CO 2 emissions in the face of population growth and increasing energy demand. However, it is essential to assess the regional climate impacts of hydropower reservoirs in order to plan these projects effectively and ensure a successful energy transition. Land use changes associated with impoundment affect albedo and surface temperature, thereby influencing the local radiation balance. This article analyzes the impact of the implantation of a hydroelectric reservoir (50.69°N, 63.24°W) on the local climate in a subarctic environment. The study shows that the installation of the reservoir led to a cooling of the local climate by −21 W/m 2 . This cooling is mainly due to an increase in the annual albedo of the reservoir compared to the previous land use, which was mainly forested. This effect is particularly pronounced at higher latitudes, where snow and ice are present for much of the year, increasing the reflection of sunlight. In addition, slight surface warming in winter and autumn and cooling in spring and summer have been observed following the impoundment. This study highlights the importance of thorough assessment of local climate impacts from hydropower projects to validate their environmental benefits. , Key Points The impoundment of a subarctic reservoir notably raised winter albedo while lowering summer albedo Reservoir impoundment altered seasonal temperatures, delaying peaks by 3–5 weeks and warming autumn/winter while cooling spring/summer Reservoir impoundment induced −21 W m −2 net cooling, with winter deficit (−60 to −140 W m −2 ) exceeding summer surplus (+5 to +50 W m −2 )

Climate variability and flow management impact phytoplankton biomass in a shallow reservoir - Spence, Danielle S.; Painter, Kristin J.; Nazemi, Ali; Venkiteswaran, Jason J.; Baulch, Helen M. (Environmental Science: Advances, 2025)
This study shows that climate oscillations and changing flow sources impact bloom dynamics in a shallow reservoir. These changes in bloom dynamics have important implications for drinking water treatment and key lessons for water management. , Shallow, eutrophic lakes often exhibit high and extremely variable phytoplankton biomass. This variability makes drinking water supply from shallow lakes particularly vulnerable to rapid change, as phytoplankton blooms can strongly impact treatment processes. Using 39 years of water quality data (typically bi-weekly), this study investigates the roles of climate variability and flow management in driving change in chlorophyll a (an indicator of phytoplankton biomass) in a shallow, hydrologically managed drinking water reservoir. Generalized additive modelling shows a significant increase in phytoplankton biomass (1992–1997), leading to a doubling of average chlorophyll a concentrations. Interestingly, we also see a shift towards smaller spring blooms and larger summer blooms. Our results show this variability in phytoplankton is largely related to climate variability, nutrients, and flow source. Specifically, the increase in phytoplankton biomass coincided with periods with greater precipitation and associated nutrient-rich inflows from an agriculturally dominated catchment, along with strong El Niño events that potentially contributed to a warm, stable water column during the growing season. During high flows from the local catchment, flows from the upstream supply reservoir are typically reduced to prevent downstream flooding. However, flows from the supply reservoir have a diluting impact due to its lower nutrient concentrations. Thus, where reservoir flow sources vary in chemistry, considering water quality in flow management could help to ameliorate bloom severity and reduce drinking water treatment costs. Importantly, understanding management and climatic drivers of reservoir water quality contributes to advance planning and mitigation of risks to water treatment.

Assessing the Hydraulic Parameters of an Open Channel Spillway Through Numerical and Experimental Approaches - Motahari Moghadam, Elaheh; Saeidi, Ali; Patarroyo, Javier; Rouleau, Alain; Payan, Meghdad (Water, 2025)
The effective design and operation of hydraulic structures, particularly open channel spillways, are crucial for water resource management and flood risk reduction in dams. A clear understanding of flow properties, such as velocity fluctuations and discharge, across various depths is essential for optimizing performance. In this study, experimental analysis and numerical simulation using FLOW-3D were combined to investigate the hydraulic parameters of a scaled model of the Romaine IV spillway located in Quebec, Canada. Measurements focused on flow properties, including velocity fluctuations at various discharge rates in specific flow depths, at selected points along the spillway. The numerical model was assessed by reproducing experimental geometry, initial water levels, and boundary conditions, and through sensitivity analyses to ensure accurate flow representation. Comparisons of flow rates of 180, 240, and 340 L/s showed that while simulations with the renormalized group (RNG) turbulence model reliably predicted average velocities, they underestimated maximum values and overestimated minimum values, especially at higher discharges. The results highlight the difficulty of accurately capturing velocity extremes in turbulent flows and the need for further model refinement. This was evident from the 60% discrepancy in minimum velocities observed at the channel center. Despite these discrepancies, the study advances our understanding of spillway performance and identifies avenues to improve the accuracy of numerical modeling in hydraulic engineering.

During and after a landslide: it’s not just clay that suffers consequences, it’s people too - Maltais, Danielle (IOP Conference Series: Earth and Environmental Science, 2025)
Abstract On the evening of May 4, 1971, the population of the municipality of Saint-Jean-Vianney (Saguenay–Lac-Saint-Jean) fell victim to a severe and deadly landslide that engulfed 41 houses within minutes, creating a massive chasm and causing the deaths of 31 people of all ages. This article presents the results of a qualitative study conducted 29 years after the disaster, involving 42 adults interviewed in a semi-structured format. The participants in the study recalled the events that affected them the most, the emotions they experienced, and the consequences they faced in the months and years following the landslide. The findings show that, regardless of their level of exposure, all respondents were deeply affected by what they had experienced and felt that the event had profoundly disrupted many aspects of their lives.

Performance of Hydraulic Models Compared to Geomorphological and Botanical Approaches to Delineate the Ordinary High Water Mark for Small Rivers - Houndekindo, Freddy; Vaillancourt, Mathieu; Duchesne, Sophie; St‐Hilaire, André; Poulin, Monique; Gignac, Charles; Bergeron, Normand (Ecohydrology, 2025)
ABSTRACT The ordinary high water mark (OHWM) delineates the water environment from the land environment. The preferred method for the OHWM delineation in Québec, Canada, is a method based solely on bank vegetation characteristics, positioning the botanical OHWM (BOHWM) at the transition from hydrophytic to terrestrial vegetation. However, in anthropized landscapes, the implementation of this botanical method is problematic due to vegetation disturbance on the shoreline or riverbanks. The hydraulic and geomorphological methods position the OHWM at the 2‐year flood line and at the bankfull level of the river, respectively. The aim of this study was to compare the position of the 2‐year flood line to the BOHWM and to the geomorphological bankfull level for rivers located in agricultural, urban and forest areas. Results showed that the best concordance between the 2‐year flood line and the BOHWM was in agricultural areas (mean distance = 1.31 m) and the least in forest areas (mean distance = 3.31 m). The best agreement between the 2‐year flood line and the geomorphological method was found in agricultural (mean distance = 1.27 m) and urban (mean distance = 1.67 m) areas, while these two methods disagreed the most in forest areas (mean distance = 3.55 m).

A Review of Urban Flood Disaster Chain Research: Causes, Identification, and Assessment - Gao, Xichao; Wang, Pengfei; Yang, Zhiyong; Liang, Weijia; Lou, Wangqi; Zhou, Jinjun (Water, 2025)
Urban flood disasters have become one of the most significant natural hazards under the dual pressures of rapid urbanization and intensified climate change. With the increasing interconnection among urban subsystems, these disasters often evolve into urban flood disaster chains, characterized by cascading failures across infrastructure, environment, and society. Current research hotspots mainly focus on three key aspects: the formation mechanisms, identification methods, and risk assessment approaches of urban flood disaster chains. In terms of formation mechanisms, most studies qualitatively describe the triggering and transmission processes of cascading events, revealing how interactions among hazard-inducing factors, disaster-formative environments, and disaster receptor generate chain reactions. Identification methods are categorized into four paradigms: qualitative identification based on experiential reasoning, semantic identification driven by data, structural identification through model inference, and behavioral identification using simulation modeling. Risk assessment approaches include historical disaster analysis, indicator-based evaluation models, uncertainty models, numerical simulation models, and intelligent algorithm models that integrate machine learning with physical simulations. The review finds that, due to the scarcity and heterogeneity of disaster chain event data, existing studies lack a unified quantitative framework to represent the mechanisms of urban flood disaster chains, as well as dynamic identification and assessment methods that can adapt to their evolutionary processes. Future research should focus on developing integrated mathematical paradigms, enhancing multisource data fusion and causal reasoning, and constructing hybrid models to support real-time risk assessment for urban flooding disaster chains.

Water security in Southern Africa: addressing climate change, governance failures, and infrastructure challenges through adaptive solutions - Mokone, Neo (Frontiers in Water, 2025)
Water security is a major challenge in Southern Africa where climate change, weak governance, and aging infrastructure threaten sustainable water access. The paper aims to assess the state of water security in Southern Africa and highlight adaptive strategies for sustainable management. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020), the paper synthesize existing research on water availability, climate change, infrastructure, and governance focusing on Botswana, Mozambique, Namibia, South Africa, Zambia, and Zimbabwe. Findings reveal significant inequalities in water access: rural households face unreliable and unsafe supplies, while urban systems are strained by population growth. Climate-induced droughts and floods intensify scarcity, threatening agriculture, energy, and health. Poor institutional coordination and limited investment further constrain effective water management. Women in rural areas bear unequal water collection burdens, deepening inequities. The paper calls for sound water governance and investment in climate-resilient infrastructure. It also advocates for regional cooperation and gender-inclusive policies to ensure fair and sustainable water access. By consolidating fragmented literature, it contributes actionable insights for policy and resilience planning. Its implications extend to guide policymakers in developing adaptive, fair, and long-term water management strategies in response to growing climate and socio-economic pressures.

Changes in channel–floodplain processes of the north Jiudong Basin, NW China, connected with climate change across the mid‐Pleistocene - Chen, Dianbao; Wang, Ke; Liu, Wei; Hu, Donghong; Chen, Dexuan; Pan, Baotian (Earth Surface Processes and Landforms, 2025)
Abstract Knowledge of how the avulsion style of river, channel mobility and floodplain reworking changes under different paleoclimatic conditions, helps to understand the morphodynamics of fluvial intrinsic behaviours and its impact on shaping basin alluvial stratigraphic architecture. In order to elucidate the relationship between extrinsic factors and internal fluvial processes, here, we explored how river morphodynamics change across the mid‐Pleistocene climate change. Sedimentary facies analyses in the Jiudong Basin of western‐central Hexi Corridor were applied to constrain changes in channel‐floodplain processes. Ten lithofacies and nine facies associations involved in general shallow lake, delta front, delta plain, overbank and channel sub‐environments were identified. These data do show evidence of elevated channel mobility, floodplain reworking and avulsion style changed significantly after 0.8 Ma. Taken together with studies of erosion rate/sediment flux variability and paleoclimate evidence from the region, the most plausible explanation of these findings from the Jiudong Basin is that, sedimentary processes subjected to declining vegetation and floodplain cohesiveness, due to a dry and unstable climate, experienced accelerated channel dynamics after 0.8 Ma. In the context of climate change across the mid‐Pleistocene, these findings provide an important perspective on the complex links between fluvial dynamics, floodplain reworking and climate change.

TSA ‐ DOT : A Decision Support Tool for Designing and Optimising Nature‐Based Solutions for Flood Mitigation - Roberts, Martyn T.; Geris, Josie; Quinn, Paul F.; Hallett, Paul D.; Wilkinson, Mark E. (Journal of Flood Risk Management, 2025)
ABSTRACT Nature‐based solutions, such as temporary storage areas (TSAs), are increasingly implemented within natural flood management strategies to mitigate flooding and soil erosion by attenuating surface runoff during storm events. However, guidance on optimising site‐specific TSA designs for runoff attenuation remains limited, and no existing approach comprehensively evaluates TSA effectiveness across multiple flood mitigation metrics. This study addresses these gaps by introducing the TSA Design Optimiser Tool (TSA‐DOT), a decision support tool for designing and optimising TSAs as effective nature‐based solutions for runoff attenuation, contributing to flood mitigation. The tool evaluates TSA performance using five flood mitigation metrics: storage efficiency index, mean retention time, peak flow attenuation, peak flow reduction, and changes in peak flow travel time. It incorporates site‐specific data such as topography and potential storage capacity, soil infiltration rates, and design storm events. Users can prioritise and customise flood mitigation metrics, making the tool suitable for a wide range of catchment settings. When applied at two agricultural TSA sites in northeast Scotland, the tool identified the importance of optimising storage‐to‐drainage relationships for effective runoff attenuation and highlighted the need for increased storage capacity or drainage adjustments under extreme storm events or limited soil infiltration. TSA‐DOT provides practical guidance for using TSAs as part of flood risk management, with integration potential into catchment‐scale hydrological models for scalable, site‐specific applications.

Abstract The frequency and intensity of flood disaster events are increasing. It is well documented that community flood vulnerability and impacts vary depending on household attributes. Nevertheless, vulnerable households in high flood risk areas rarely invest time and effort to reduce their vulnerability. A mixed‐methods case study investigated the key factors that shaped flood risk perceptions, awareness levels, and information accessibility among households with three levels of vulnerability. Flood concerns were found to increase with household vulnerability and having a vulnerable family member elevated flood disaster risk. Disaster awareness is affected by household attributes such as evacuation assistance for vulnerable family members, as well as by support from government/community groups. Personal networks, including families and neighbours, are primary flood information verification sources, with WhatsApp being the main social media platform utilised. The findings suggest that governments should tap into trusted community and social networks to disseminate flood risk communication to reduce disaster vulnerability.

A systematic review of methods for identifying drought-flood abrupt alternation: advances and future directions - Zhao, Lin; Aiyub, Kadaruddin; Ata, Frankie Marcus; Lam, Kuok Choy; Sun, Mengzhu (Frontiers in Environmental Science, 2025)
Drought-flood abrupt alternation (DFAA) events, characterized by compound extremes and rapid transitions, pose significant challenges for accurate identification. Although existing research has reviewed DFAA event identification, it pays insufficient attention to emerging concepts related to DFAA and characterization variables and lacks a comprehensive summary of methodological advancements under climate change. To fill these gaps, this study systematically reviews 55 publications by proposing a unified definition framework, synthesizing identification and characterization methods, evaluating recent methodological advances, and outlining future directions for improving DFAA identification. This review shows that (1) 58% of studies utilize traditional drought-flood indices and indicators, whereas 42% propose DFAA-specific indices; (2) traditional methods often disregard key DFAA characteristics, treating droughts and floods as separate events rather than as a unified process; (3) advanced methods incorporate key features such as alternation points, transition time, and transition speed, yet challenges remain in accurately capturing abrupt transitions; (4) future research should integrate multi-source datasets and apply dynamic time windows to improve DFAA identification, while aligning advances with policy to strengthen early warning and risk management.

Changes in Agricultural Soil Quality and Production Capacity Associated with Severe Flood Events in the Sava River Basin - Zupanc, Vesna; Cvejić, Rozalija; Golob, Nejc; Lipovac, Aleksa; Predić, Tihomir; Stričević, Ružica (Land, 2025)
Intensifying urbanization in Central Europe is increasingly pushing flood retention areas onto private farmland, yet the agronomic and socio-economic trade-offs remain poorly quantified. We conducted a narrative review of published field data and post-event assessments from 2014–2023 along the transboundary Sava River. Information was collected from research articles, case studies, and environmental monitoring reports, and synthesized in relation to national and EU regulatory thresholds to evaluate how floods altered soil functions and agricultural viability. Water erosion during floods stripped up to 30 cm of topsoil in torrential reaches, while stagnant inundation deposited 5–50 cm of sediments enriched with potentially toxic elements, occasionally causing food crops to exceed EU contaminant limits due to uptake from the soil. Flood sediments also introduced persistent organic pollutants: 13 modern pesticides were detected post-flood in soils, with several exceeding sediment quality guidelines. Waterlogging reduced maize, pumpkin, and forage yields by half where soil remained submerged for more than three days, with farm income falling by approximately 50% in the most affected areas. These impacts contrast with limited public awareness of long-term soil degradation, raising questions about the appropriateness of placing additional dry retention reservoirs—an example of nature-based solutions—on agricultural land. We argue that equitable flood-risk governance in the Sava River Basin requires: (i) a trans-boundary soil quality monitoring network linking agronomic, hydrological, and contaminant datasets; (ii) compensation schemes for agricultural landowners that account for both immediate crop losses and delayed remediation costs; and (iii) integration of strict farmland protection clauses into spatial planning, favoring compact, greener cities over lateral river expansion. Such measures would balance societal flood-safety gains with the long-term productivity and food security functions of agricultural land.

Robust adaptive pathways for long-term flood control in delta cities: addressing pluvial flood risks under future deep uncertainty - Hu, Hengzhi; Ke, Qian; Wu, Wei; Zhang, Min; Wu, Yanjuan; Jin, Chengming; Wen, Jiahong (Hydrology and Earth System Sciences, 2025)
Abstract. Delta cities are increasingly vulnerable to flood risks due to the uncertainties surrounding climate change and socioeconomic development. Decision-makers face significant challenges in determining whether and how to invest in flood defense. Adaptation solutions should consider not only robustness but also adaptiveness in case the future unfolds other than as expected. To support decision-making and meet long-term multi-objective targets, we propose a synthesized framework that integrates robustness analysis, adaptiveness analysis, and pathway generation. This framework was applied to evaluate alternative solutions for managing pluvial flood risk in central Shanghai. The results demonstrate that relying on a single-objective decision-making approach (focused only on robustness) can lead to biased outcomes. By examining the effectiveness period and flexibility of candidate solutions, we assessed their potential to meet long-term flood control targets. The analysis reveals that a combined option – incorporating increased green areas, an improved drainage system, and a deep tunnel with a 30 % runoff absorption capacity (D + G + Tun30) – emerged as one of the most robust and adaptive pathways, based on multi-objective trade-off analysis. This study highlights the importance of considering effectiveness period within predefined control targets and retaining flexibility to avoid path-dependency and minimize long-term regrets. The proposed framework is broadly applicable and can guide adaptive responses to future flood risks in other delta cities.
