Abstract: Drainage problems in the coastal area of Egypt cause reduction of agricultural production and suffering of people, which leads to find a sustainable drainage management. During rainy seasons, frequent flooding by storm water is one of the most serious problems, causing heavy effect on transportation, agriculture, industries and economic activity. This paper presents simulation of unsteady flow model representing the Edko drain, in the Western Delta area in Egypt. This drain discharges its water by gravity into a natural salt lake (Edko Lake), which is in turn connected with the Mediterranean Sea through a bay called the El-Maadia Bay. A numerical model is considered for flood routing in a drainage network, where the flow is affected by the released drain flow, the Edko Lake water level, and tides in the Mediterranean Sea. From the simulation, it was found that the tidal flow is restricted in the lake. For flood mitigation, the reduction of peak flow was suggested through dredging the excess sedimentation in Edko Drain cross section. Land management is reflected directly in the simulated water levels by cutting a local mound. This solution has a good result for flood control in this drainage system.
