Assessing Flash Floods Prone Regions at Wadi basins in Aswan, Egypt

Abstract

It is well known that flash floods are very devastating for human life and their properties. The main target of this paper is to investigate and determine the prone urbanized regions along the River Nile, Aswan, Egypt relying on numerical simulation and field survey. Recent flash floods impacts in Egypt were discussed showing the real effects on both wadi residences and urbanized regions. Investigation and exploring the prone urbanized regions and agriculture lands for flash floods threat at some wadi basins in Egypt were conducted based on the field survey and rainfall -runoff modelling. The GSMaP precipitation was used for simulation of flash floods at the target wadi basins. The simulation has been successfully carried out for several flash foods events. Inundation maps showing the affected regions (urbanized and agricultural) due to flash floods were developed. Consequently, proper mitigation strategies should be considered based on this study to re-manage or re-allocate the urbanized regions in order to avert flash floods. Further applications would be more effective considering the risk disaster mapping based on several important criteria.
