In recent decades, floods have been the most common, complex, and destructive natural calamities worldwide. Hence, for inclusive flood risk assessment, creating susceptibility mapping to demarcate flood-vulnerable zones is fundamental decision makers. To assess flood-prone locations in Akre, Iraqi Kurdistan Region, was undertaken using geographic information systems, remote sensing, an analytic...
Decades of academic discussion on social resilience have led to the development indicators, indexes, and different approaches assessing it at national local levels. The need show real-world applications such assessments is evident since became a political disaster risk reduction governance component. This article gives full description methodology used develop SoResilere, new index applied floo...
BACKGROUND Flood preparedness empowers the community to respond effectively to related hazards. However, there was no research done in the country concerning household flood preparedness. Therefore, the aim of this study was to assess household flood preparedness and associated factors in the flood-prone community of Dembia district, northwest Ethiopia. METHODS A community-based cross-section...
Flood regime and vegetation flood tolerance interact to influence tree growth in riverine landscapes. We studied tree growth in floodplain and upland forests of theWisconsin River. About a century ago, levees set back from the river were constructed on this floodplain. The levee restricts some floodplain area from overbank flood events, but leaves a portion of active floodplain still inundated ...
A 2D-hydraulic flood propagation models require accurate elevation data. One of the main problems is frequent changes of land use in major cities, where frequent updating of the digital terrain model (DTM) for flood modelling might be needed. On the other hand the assessment should be based on realistic flood hazard indicator that would help to reflect the real impact of urban development on th...
This study presents an advanced remote sensing-based steady-state flood model to improve flood management strategies. The REFIX (Regression and Elevation based Flood Information eXtraction) model is based on regression analysis and uses a remotely sensed flood extent and a high-resolution floodplain DEM (Digital Elevation Model) to estimate water heights for a given flood event. In some cases, ...
