Abstract
Flash floods are considered as catastrophic phenomena possessing major hazardous threat to the coastal cities, towns, villages and infrastructures. This study deals with the evaluation of flash flood hazard in the basins in Eastern coast between Marsa Alam and Ras Gharib depending on detailed morphometric parameters. For the detailed study, ASTER data were used for preparing digital elevation model (DEM) was used in the evaluation of linear, areal and relief aspects of morphometric parameters. The major parameters such as watershed boundary, basin slope, length and stream ordering are prepared using WMS and Arc map software. Forty-eight morphometric parameters were measured, calculated and interlinked to produce fifteen effective parameters by using the statistical analysis, using Pearson correlation for evaluation of the flash flood hazard degree of the study area. Based on the morphometric parameters which affect the hydrologic behavior of the basins, by influence on time of concentration which has a direct influence on flooding prone area. The flash flood hazard of the basins was identified and classified into five groups (high, moderate high, medium, moderate low and low hazard degree). The study provides details on the flash flood-prone area and the mitigation measures. This study also helps to plan rainwater harvesting and watershed management in the flash flood alert zones.
