Abstract The water intakes along the Nile River have been used for multipurpose such as treated plant for drinking water, cooling water for electrical power station, etc. The selection of water intake location represents an important issue to minimize problems that hider the water withdrawal process and as a result increase the intake efficiency in addition to reduce the maintenance and cost. Some of the widely known problems that affect the efficiency of the water intakes is the accumulation of sediment on front of the intake. Such problem leads to decrease the water abstract capacity of intake, in addition to cause damage in the propeller of the pumps due to the abstract of fine sediment. This thesis studies the optimum hydraulic location of water intakes in the Nile River basin. Data for site description, water levels, velocity measurements and sediment have been collected and used in model setup and calibration. A hydrodynamic model for the fourth reach was developed and calibrated using Delft3D software. The morphological changes for four study areas were calculated for ten years for the study area and fifteen locations have been simulated. The analysis was done for the morphological changes for each location after 1 year for short term, 5 years for medium term and 10 years for long term. The results were compared by the present situation where no plant intake exists. Finally, three locations were chosen as the optimum location where there is no sediment in front of the intake compared with the other locations in the same study area. The procedures done in this research can be used for different reaches on Nile River and can be used in solving the problem of intake shutting down in Nile basin countries |
