Application of geographic information systems and remote sensing are a powerful tool for the assessment of risk and management of flood hazards. By using these techniques to extract new drainage network with more details to prepare natural hazard maps which may help decision makers and planners to put suitable solutions reducing the impact of these hazards. Ras Sudr city and surrounding area had been attacked by flash floods of Wadi Sudr and Wadi Wardan which are nearly perpendicular to the eastern side of the Gulf of Suez, Egypt, and many infrastructures had destroyed. GIS techniques and remote sensing are used to find the interrelation between the morphometric parameters by using statistical correlation to determine the area under varying flood conditions. The results of morphometric parameters and the new data of last flood which occurred on 17-18th January 2010 indicate that the two basins are threatened by the risk of flash floods and Wadi Wardan is more risky than Wadi Sudr.
