In Egypt, enhancing river transport in Dammietta Branch by Dredging was conducted since 1999. About six million meter cubic of bed material was removed with a huge amount of Egyptian pounds. A navigation hazard represented by a drop of 0.5m in the designed water level was evident in 2006.The drop of water level was threatening the satisfaction of 2.3m water depth for safe navigation during low discharges within the year. Therefore, the book objective is to improve the navigation condition downstream Zefta Barrage (Map locations are shown in the book) on Dammietta branch by installing permanent regulation structure such as weirs. The weirs will enhance heading up of water in the weir backwater zone to solve most of the navigation bottlenecks. Hydro graphic and topographic data were collected from the study area and was analyzed to prepare a reasonable database for the model ( SOBEK – A one dimensional mathematical model) to find a better solution with economic point of view. ...
