Advanced technical modelling can now inform impact assessments and evaluate interventions to mitigate these risks, yet such analyses are often not supported by adequate governance frameworks to facilitate the implementation of the proposed solutions. This leads to disconnects between technical analyses and decision-making and to missed opportunities to provide evidence-based prevention. Public spending tends to be skewed towards visible, post-event recovery, while diffuse prevention investments are persistently deprioritised. The coastal town of Kineta in Greece exemplifies this case: detailed flood modelling and design of post-wildfire erosion and flood protection treatments (PEFTs) were developed in prior work, but have not been implemented. Drawing on those previously published simulation results, public-domain documentary evidence and the authors' direct engagement with the case, the values–rules–knowledge (VRK) model of decision contexts was used as a diagnostic tool to identify the local flood governance approach. The diagnosis is presented as an expert-informed synthesis with a transparent audit trail. It identifies recurring value-rule, value-knowledge and rule-knowledge interactions that create persistent barriers to action in Kineta. This diagnosis involved the collation and synthesis of reported and observed interactions of the behavioural, cultural, disciplinary and regulatory dimensions of flood-risk governance that explain the persistence of inaction. A three-stage participatory roadmap is then proposed to translate flood-risk modelling outputs and VRK analyses into policy- or practice-relevant insights that lead to more timely and targeted investment in PEFTs.</p>","PeriodicalId":49294,"journal":{"name":"Journal of Flood Risk Management","volume":"19 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jfr3.70240","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In response to increasing climate extremes, Nature-based Solutions (NbS) have emerged as a sustainable and multifunctional approach to flood risk management (FRM), integrating ecological, social, and engineering benefits. While NbS have been widely implemented across the globe, their large-scale adoption in Australia remains limited. This study therefore aims to identify the underlying barriers constraining NbS uptake and the enabling mechanisms that can support their mainstreaming within Australia's FRM framework. A systematic literature review (SLR) was conducted, revealing six major barrier clusters: (B1) Institutional and Governance Fragmentation, (B2) Financial, Economic, and Market Constraints, (B3) Technical, Knowledge, and Data Limitations, (B4) Socio-Cultural and Perceptual Barriers, (B5) Physical, Environmental, and Spatial Constraints, and (B6) Conceptual, Methodological, and Epistemic Challenges. Conversely, six enabler clusters were identified: (E1) Policy, Legislation and Institutional Frameworks, (E2) Collaboration, Intermediaries and Multi-Level Partnerships, (E3) Community Awareness, Social Licence and Co-Design, (E4) Finance, Incentives and Business Cases, (E5) Evidence, Data, Tools and Decision Frameworks, and (E6) Design Integration, Multifunctionality and Implementation/Pilots. Building on these findings, this study provides a structured synthesis of fragmented Australian NbS literature by integrating governance, financial, technical, socio-cultural, and environmental dimensions influencing implementation pathways for FRM. The study also proposes a conceptual relationship framework linking the six barrier and enabler clusters, illustrating how enabling mechanisms can systematically address implementation challenges. Rather than advancing a new theoretical model, the framework serves as an integrated and implementation-oriented synthesis tool to support policymakers, planners, and practitioners in overcoming institutional fragmentation, strengthening coordination, and advancing NbS integration within Australia's future flood adaptation strategies.</p>","PeriodicalId":49294,"journal":{"name":"Journal of Flood Risk Management","volume":"19 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jfr3.70243","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review addresses the need for a systematic and decision-oriented synthesis of how space-borne remote sensing has evolved toward integrated flood monitoring and disaster risk reduction frameworks. Moving beyond conventional sensor inventories, the study examines sensor integration pathways, temporal evolution, and decision relevance. Four research questions guide the analysis: (RQ1) how space-borne sensors have been applied and advanced in flood studies, (RQ2) how multi-sensor fusion architectures have evolved, (RQ3) what limitations persist, and (RQ4) what future directions are emerging. Following PRISMA guidelines, 176 peer-reviewed studies published between 2001 and 2024 were systematically analysed. Quantitative synthesis indicates a marked post-2018 increase in multi-sensor approaches, alongside a growing share of studies adopting fusion frameworks. Synthetic Aperture Radar (SAR)-centred integration systems represent a dominant share of recent applications; most commonly combined with precipitation products and digital elevation models. Analytical synthesis further indicates that SAR plays a central role in flood detection, while precipitation and topographic data provide key hydrological drivers and terrain constraints. These findings indicate a transition from static flood mapping toward process-aware, multi-sensor, and algorithm-driven flood intelligence systems. The review also highlights the growing role of artificial intelligence and cloud-based platforms in enabling scalable, near-real-time flood analysis. It concludes that future flood resilience increasingly depends on the coordinated integration of space-borne observations, advanced analytics, and operational decision-support architectures. This synthesis provides a unifying framework to guide next-generation flood monitoring and disaster risk reduction under accelerating climate change.</p>","PeriodicalId":49294,"journal":{"name":"Journal of Flood Risk Management","volume":"19 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jfr3.70214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines how personal disaster experience, village communication, and social media shape farmers' perceptions of future flood loss and planting intentions in the Hetao Irrigation District of Bayannur City, Inner Mongolia Autonomous Region, China. The case is analytically important because recent flood shocks emerged in a historically drought-oriented human-water system. Based on a field survey of 591 farmers and analyzed using linear and generalized linear mixed-effects models, the results indicate that personal disaster experience is the strongest predictor of future flood loss perception and is also associated with lower willingness to expand cultivated land. Media-based disaster comparison significantly increases perceived future drought loss but does not further increase perceived flood loss. Community disaster communication does not directly heighten flood risk perception, yet it is positively associated with plans to expand production. The study identifies which information channels make flood loss salient and consequential for farm planning after recent events. The findings show that recent flood memory now dominates local risk cognition in this drought-oriented irrigation system. Flood risk management in such settings should combine recent lived experience, locally specific guidance on waterlogging and drainage, and community-based recovery support to strengthen agricultural resilience.</p>","PeriodicalId":49294,"journal":{"name":"Journal of Flood Risk Management","volume":"19 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jfr3.70244","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes and applies a comprehensive methodological framework for evaluating torrential flood hazards. Although existing methodologies assess such events based on geological, geomorphological, hydrological, and land cover conditions, they often overlook the dynamic interaction between channel evolution, lateral scour, sediment transport, and progressive slope destabilization over time. In this context, the study incorporates the concept of Accumulated Geotechnical Deterioration (AGD) associated with recurrent torrential and erosive processes affecting the channel–slope system. The methodology is applied to the La China River in the Cortinas sector (Toledo, Colombia), identifying high hazard levels at the stream's confluence and headwaters. The research demonstrates the importance of integrating sediment load estimation, multitemporal evaluation of fluvial dynamics and slope stability to better understand the relationship between progressive instability processes and hazard levels in the study area.</p>","PeriodicalId":49294,"journal":{"name":"Journal of Flood Risk Management","volume":"19 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jfr3.70239","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these measures, the installation of leaky wooden dams (LWDs) at catchment scale is a widely used intervention aimed at slowing flow and desynchronising runoff peaks between sub-catchments, thereby reducing flood magnitude. Despite their popularity, the long-term effectiveness of LWDs and particularly their influence on sediment transport and catchment-scale hydro-geomorphic connectivity remains poorly understood. To address this knowledge gap, we used a modified version of the CAESAR-Lisflood landscape evolution model to simulate the hydrological and geomorphic impacts of LWDs within a proxy of a catchment in North Yorkshire, UK. We ran a suite of 20-year numerical experiments driven by a spatially variable, convection-permitting rainfall timeseries to explore how the spatial configuration, stream order placement, and density of LWDs affect flood peak attenuation. All LWDs simulated were representative of channel-spanning structures within the catchment, with a uniform starting gap size of 0.2 m and height of 1 m. Results show that LWDs installed on first-order streams were most effective, reducing flood peaks by up to 44% and increasing both water and sediment retention. LWDs placed on higher-order streams had a limited overall impact, though they could reduce individual peaks by up to 35% in some instances, whilst in other cases, flood peaks were amplified by as much as 77%. Importantly, the introduction of LWDs increased geomorphic variability across the catchment. This included both enhanced erosion and deposition along channel segments, with first-order LWD placements generating the greatest geomorphic response. Furthermore, interactions between LWD in different stream orders and sub-catchments led to unexpected and non-linear effects, altering sediment transport regimes and morphodynamic feedbacks throughout the network and changing the efficacy of flood peak attenuation over time. These findings highlight the critical importance of spatial placement and stream network interactions in determining the long-term hydrological and geomorphic efficacy of LWDs, with notable implications for the design and installation of future catchment-scale natural flood management strategies.</p>","PeriodicalId":49294,"journal":{"name":"Journal of Flood Risk Management","volume":"19 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jfr3.70238","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148462792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A mixed-methods social science research study investigated how select FIM products are used for decision support, what barriers exist to using their information, and what improvements to design and delivery could improve their usefulness. Professional and residential participants in scenario-based focus groups and surveys in the Mid-Atlantic and West Gulf River Forecast Center regions provided feedback on FIM use and design that was incorporated into redesigned versions. These revised FIM products were tested in a follow-up online survey with professionals gathering more detailed feedback on what elements of the maps and design were most helpful for their needs. Many of the proposed changes were reviewed positively, including color transparency, localization (labeling/geographic context), delineation of the ordinary high-water channel, and inclusion of critical infrastructure and evacuation routes. Findings also describe user needs for FIM products to offer historical context, probabilistic information, and mobile accessibility.

This research aims to contribute to this by examining Aotearoa New Zealand's flood hazard and risk maps and their application to land-use planning. Drawing on empirical data and document analysis, findings indicate that most flood mapping focus on the meso (regional) and micro (local and site/property) spatial scales with different applications for land-use planning. Findings also indicate that land-use planning decisions informed by flood hazard and risk maps can be inconsistent due to a lack of national guidance and directives on how to use this information. There is also lack of transparency and communication regarding the appropriateness of flood hazard and risk maps produced at different scales based on the needs of the general public and planning sectoral needs.
