| Egypt is characterized by its arid condition. In the last few years, attention has been devoted to the North-Western coast of Egypt due to the large urbanization activities in it. The government spares no effort to develop it. Many comprehensive planning studies have been conducted and many luxurious tourist spots have been built. Thus, flood management and analysis of this area has become a must.<br>
Intense stream networks distinguish the desert geomorphology, which is subjected to harsh climatic conditions, and extreme water scarcity. However, different stream networks, especially along the sea coasts and the Red Sea Mountains, are subjected to extreme precipitation events in the form of flash floods, where a considerable amount of rainfall occurs, suddenly, for a short duration, and with a relatively long time period. Flood management has mainly two objectives: (1) benefiting from the available flood water during water scarce period, and (2) mitigation actions to minimize the damage caused by flash floods.<br>
A methodology for flood prediction, risk assessment, and vulnerability estimation is extremely important. The using of GIS techniques has allowed us to read and comment on all the resulting maps. We have also discovered that the impact risk will not be calculated if any of the following factors is verified, i.e. high rate of rain falls in short time span, existence of any strategic buildings, projects, or external and mature drainage networks. |
