Abstract

The main object of the present study is  to assess and produce flash flood hazard  map to Wadi Gharandal based on the morphometric analysis with the aid of the techniques Remote sensing (RS) and geographic information system (GIS) ASTER DEM data  are used  to extract the stream network to assess the morphometric parametric and to make risk zone map of the study area. (GIS) and (RS) have been utilized for the morphometric analysis of wadi Gharandal basin southwestern Sinai, Egypt. Several morphometric parameters have been computed and analyzed, such as, circularity ratio, elongation ratio, form factor ratio, stream frequency and bifurcation ratio. Impacts of morphometric parameters on flash flood characteristics have been also investigated. Wadi Gharandal is divided into eighteen relatively large sub-basin, nine of them have high susceptibility for flooding, six have medium susceptibility and about three have low susceptibility for flooding.
