High Aswan Dam is the most important construction on the Nile River for water storage and control. The dam experiences sedimentation problem upstream the lake. The rate of reservoir sedimentation depends mainly on the size of a reservoir relative to the amount of sediment flowing into it. Through this study, a number of scenarios has been tested to numerically study the expected morphological changes that might take place in HADL as a result of the possible reduction of the incoming flow and/ or the sediment loads due to any possible dam construction activities upstream. The mathematical model was first verified to represent the conditions of the lake second; the model was evaluated then applied to the developed scenarios to predict the sediment transport in the longitudinal direction and sedimentation zone extension along the lake and to estimate of the expected total sediment volume
