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
