MODELING FOR FLOOD PREVENTION FOR THE COASTAL AREA OF NILE DELTA IN EGYPT

Abstract

Excess agricultural drainage water in Egypt is mainly disposed into the sea through a complex network of drains. Recently, the area around the Edko Drain in the west delta region faced problem of frequent flooding by storm water during the rainy season. A solution for the problem is presented in this paper through 1-D numerical simulation for flood routing in a drainage network, where the water surface level is affected by the released drainage flow, the lake water level, and the tide in the Mediterranean Sea. From the drainage model, it is concluded that the influence of tidal flow is restricted in the lake area and not extended to the drain reaches. As for flood mitigation, lowering of drain water levels is suggested through cutting the local mound in the drain.
