In the upcoming decades, the potential threats of water are predicted to increase dramatically and this is partially because of climate change which has a great effect on both water quality as well as sediment transport. Egypt is mainly depending on the Nile River with 95% of its renewable water resources. In Egypt few trials have been conducted for numerical simulation of the water quality in parts of the Nile River downstream Aswan High Dam (AHD) or in other water streams. The framework that will be used to evaluate water flow and sediment transport requires generally the following three types of model formulations: hydrodynamic, sediment transport and water quality models. TELEMAC-MASCARET model for 2D flow will be used in simulation of sediment transport and water quality.
The general objectives of the developed models are to:
