Morphometric-hydro Characterization of the Coastal Line between El-Qussier and Marsa-Alam, Egypt: Preliminary Flood Risk Signatures

Egypt is highly exposed to flash flood hazards, particularly in Sinai Peninsula and along the Red Sea coast, causing sudden huge damages constructions losses human lives during a very short time. This paper investigates dominant characterization of morphometrical features their relationships with hydrological behaviors an important strip western coast. The study focuses on analyzing October 2009 2019 storm events coastal area between EL-Qussier Marsa Alam order intiate preliminary risk assessment model. Morphometric entire zone provide complete scenario nature catchments sub-catchments development. Numerous morphometric indexes such as geometry, areal indexes, linear relief were examined through processing different sets data. Modern techniques remote sensing geospatial analysis applied process spatial spectral model (HEC-HMS) WMS software was run delineate extract peak flow hydrograph curves for main catchments. results water amounts calculated using SCS unit approach. characteristics major reveal conditions moderate levels flooding. ended number recommendations that could minimize negative effects hazards.
