Abstract
The aim of this research work is to study the sedimentation process at the
intake of the Rowd El-Farag pump station. A Nile reach with a length of 1.53
km was selected where the pump station is at the middle. The selected reach
covers the area from km 7.78 to km 9.31 downstream El-Roda gauging stations
(km 934.785 to the km 936.31 from Aswan dam). The reach is nearly straight.
There are some low lands (shallow areas) in the eastern bank of the river, at the
intake.
A two-dimensional numerical model called (CCHE-2D) is used to
simulate and predict the sediment transport in terms of the depth- averaged
sediment concentration. Field data collected by NRI were used in the simulation
and calibration of the model. Statistical measurements indicated that the model
results are accurate enough for practical purpose and hence the model could be
used to predict the morphological changes of the study area.
The model has been applied to predict the different cross sections along
the study reach at years 2017. The results show that, the intake of the pump
station locates in deposition area.
The research recommended that usmg of dredging as a sustainable
solution for sediment control at Water Intake of Rowd El-Farag Pump Station
although this solution is an expensive solution. Dredging the study area at level
13.50 (1.50 m) below minimum water level.
