Recent flash flooding in the Yan region of Kedah severely affected population well-being. This natural disaster has washed away large quantities logs area. In addition to examining impacts and adaptation response floods, this study examines causes floods that occur. The cause flood was determined through observations validated by information from relevant government publications, a questionnaire distributed 110 residents results indicate factors rather than illegal activities are primary floods. effects include loss destruction property, transportation, buildings agriculture. Most have adapted widening waterways river channels, but they refuse relocate safer areas. Their self-initiatives may become irrelevant if magnitude increases. provides comprehensive analysis phenomenon rural adjacent protected area demonstrates community does not accept all strategies proposed authorities. community's willingness adapt it is based on psychosocial economic factors, as well authority intervention. Thus, there need implement intervention programmes increase level preparedness face possibility such disasters future, including support effective prevention facilities also affect at bottom level.

This study focuses on assessing flash flood risks in Northeastern Thailand, particularly within the Lam Saphung, Phrom, and Chern River Basins, which are highly susceptible to floods debris flows. Using HEC-RAS hydraulic model integrated with GIS tools, research analyzes historical scenario-based events evaluate impact of land use changes hydrological dynamics. The was calibrated validated statistical metrics such as R2 values ranging from 0.745 0.994 NSE between 0.653 0.893, indicating strong agreement observed data. also identified high-risk areas, up 5.49% 5.50% increases flood-prone areas Phrom respectively, 2006 2019. Key findings highlight critical role proactive risk management targeted mitigation strategies enhancing community resilience. integration advanced modeling detailed datasets enables precise hazard mapping, including depths exceeding 1.5 m certain zones covering 105.2 km2 during severe events. These results provide actionable insights for emergency response planning. significantly contributes assessments by advancing techniques delivering practical recommendations sustainable management. outcomes relevant stakeholders, urban planners, officials, policymakers, who aim strengthen resilience vulnerable regions.

Abstract Climate change has increased flood risks in downstream Nigeria, driven by altered hydrology, dam operations, and land-use changes threatening infrastructure, livelihoods, ecosystem stability with growing frequency severity. This study analyzes patterns, identifies key environmental drivers, predicts flood-prone areas through an integrated machine learning geospatial analysis approach. Data sources included Synthetic Aperture Radar (SAR) imagery from Sentinel-1, rainfall measurements, Shuttle Topography Mission (SRTM) elevation data, surface water level records. Machine models Random Forest (RF), Support Vector (SVM), Artificial Neural Network (ANN) were applied using tools such as Google Earth Engine ArcGIS 10.5 to assess dynamics 2018 2024. Downstream regions (elevation: 78–235.1 m) exhibited greater susceptibility than upstream (up 1399.43 m). Flood extents rose 10.9% August (from 2441.91 km² 2707.75 2024) 39.8% October 3083.44 4311.55 km²). The RF model achieved the highest accuracy (92%), outperforming SVM (88%) ANN (85%). Inundated 20–35% of zones. Rainfall intensity 15–20%, annual totals exceeding 4311 mm some areas. cover declined further exacerbating risks. findings demonstrate that climate change, alteration, operations are major contributors flooding. Mitigation strategies include 10–15% reforestation, embankment construction, learning–driven early warning systems, which can reduce damage up 30%. These approaches support sustainable risk management Nigeria.

The incidence of flooding is set to rise due climate impacts in the coming years. Nigeria one countries increasingly experiencing flooding. Its urban areas are expected suffer more from concentration economic activities therein and projected population growth. To sustainably manage flood risks, there a growing call incorporate indigenous knowledge practices contemporary risk management. This work engaged with experts working field management public institutions understand if methods could positively inform modern Port Harcourt, major prone Nigerian city. It finds that applicability limited given poorly managed transformation, growth, evolution city has experienced over time. However, some practice rooted Indigenous like planting certain trees mangrove species still have utility today. government encouraged halt reclamations conversions wetlands instead, seek ways restoring bringing back these important ecosystems their natural role mitigation control. Developing forests can also play an integral managing rainwater runoff while improving overall environmental quality.

Because of its low-lying location, urbanization, and inadequate infrastructure, Jakarta (Indonesia) has experienced an increase in annual flooding events, rising from average five significant floods per year the 1990s to over 20 annually (2010-2020). With climate change exacerbating extreme weather encounters escalating risks flooding. Although recurrent is exacerbated by non-point source (NPS) pollution such as urban runoff agricultural discharge that contribute 40% total pollutants leading flood-related issues Jakarta, none investigated this research gap.

The rising incidence of flooding is a cause for global concern. Flooding caused by both natural and human factors. In Nigeria, has been attributed chiefly to factors, such as poor waste disposal practices management. Despite this known link, no empirical study have engaged with urban residents understand their actual ascertain knowledge the connection they are increasingly experiencing. This work fills gap via an in-depth engagement experts on in flood-prone city Port Harcourt mixed-methods case study. Questionnaire surveys qualitative interviews served primary data collection tools. confirms provides prevalence various forms practices. key information that can guide needed change eliminate flood driver pursuit sustainable risk pertinent management one areas where citizens agency act. A behavioural shift regard must be encouraged targeted public sensitization. Having local vanguards champion turn also recommended. relevant authorities adopt more approach ensuring there services putting place adequate disincentives deter offenders.
