Abstract
One third of land area on the Earth is arid or semi-arid, where the water is serious, either lack or excess. In the eastern of Egypt Sinai peninsula is located, and due to the importance of Sinai as a one of the major development axes for the government which try to increase/encourage the investment in this region of Egypt, The flood protection is a highly important issue due to the damage, danger and other hazards associated to floods to human life, properties, and environment.
Digital geospatial flood inundation mapping can be a powerful tool for flood risk management. Flood risk preparedness, communications, warning, response, and mitigation can be enhanced by flood inundation mapping that shows flood water extent, depth, and velocity over the land surface. Flood inundation maps that accurately reflect observed and forecasted hydrodynamic conditions enable officials to make timely operational and public safety decisions before and during flood events.
To get the runoff for inundation maps hydrologic model had setup to get the response of watershed for Rainfall. Through the hydrologic modeling some parameters had been considered like soil type and cover, land use which change with time, any obstacle in the flood stream will change water behavior.
Wadi El-Arish had been attaked in 1975 by a significant flood event, the event is the simulated event in this study, while the Shuttle Radar Topography Mission (SRTM) had been used to simulate the wadi terrain. The boundary of the flood inundation had been studied. A hydrological model of wadi El-Arish basin, using HEC-HMS was coupled with an 1D-hydraulic model of wadi stream, using HEC-RAS to generate flood inundation depth and extent of this event.
The maps showing that the water depth along the wadi varying from 0 to 9m, and velocity distribution showing the rang of velocities between 0 and 4.5m/s.
