Abstract
Flash floods are severe disasters in terms of human lives loss and economical damages. However, it is a vital source of fresh water especially for wadi system and arid environments. Modelling tools are needed for an effective flash flood management. Due to the scarcity of gauged data, hydrological modeling is carried out using alternative data as remote sensing to simulate the flash floods at wadi system. The target study area is Wadi Qena, which considered as one of the most promising areas for development in the Eastern Desert of Egypt. The adopted methodology was based on Hydro-BEAM (Hydrological River Basin Environmental Assessment Model) linked with several remote sensing data types as to overcome data limitation in wadi environments. Hydro-BEAM is a physical based distributed hydrological model. Transmission losses have been estimated using the empirical Walter equations. The simulation has been successfully carried out indicating that the proposed methodology can be used to predict the flash floods in Wadi Qena. The behaviors of flash floods have been depicted revealing that the warning time of flash floods is very short. The remote sensing data can be reasonably used to compensate measurements deficiency. Results interpretations revealed that Wadi Qena has a significant water resources where the estimated surface water that drained by the wadi outlet is equal to 71.7 million m3 for Jan-2010 and the total transmission losses is equal to 13.15 million m3. Therefore, such amount of water should be efficiently managed and utilized.
