Abstract

The arid and semi-arid regions are characterized by scarcity of water resources, an ever-increasing demand on water supplies, the paucity of data, drought and flash flood threat. So, this paper aims to introduce an effective methodology for sustainable management and efficient utilization of the water resources as well as flood control in the arid regions to sustain a minimum resource base. A physically-based, distributed hydrological model was proposed in W. Al-Khoud (Oman), W. Ghat (Saudi Arabia) and W. Assiut (Egypt). This approach can satisfactorily evaluate Wadi runoff behaviors such as discontinuously surface flow and estimating transmission losses. A comparison study has been done between different wadis to understand the effect of watershed characteristics and climatic condition on Wadi runoff. The results of numerical simulation exhibit good fitting with the observed ones however the paucity of high quality data.
