Abstract: The Middle East region affected by many disasters that are mainly flash floods and drought. In the arid environments, flash floods are among the most dangerous hazards in terms of fatalities and economical damages. However, flash flood water can be a vital source of water in such arid regions. Lack of data is the biggest hindrance for better understanding of the hydrological processes hence; there is no enough knowledge for minimizing the flash flood threats in arid areas. Egypt is one of arid countries that faces flash flood in the coastal and Nile River wadis. Until today, no proper protection from flash floods proposed for all wadi basins in Egypt. Wadi Abadi (W. Abadi) is selected at the eastern desert as a case study for flash flood simulation and mitigation. Unconventional techniques and data sources as remote sensing data used with Hydrological River Basin Environmental Assessment Model (Hydro-BEAM) to simulate and evaluate different mitigation scenarios of flash flood at the target basin. Flash food mitigation using some distributed dams and relatively bigger single concentrated dam has been compared. Both scenarios could mitigate flash flood at the downstream efficiently. However if we consider the all area of the wadi, the distributed dams can protect upstream area also from the threat of flash flood.
