Solving the problem of sedimentation at water intake of Rowd El-Farag pump station using 2D model

Abstract This research presents and analyzes the problem of sedimentation at water intake of Rowd El-Farag pump station using a 2 dimensional computational model, CCHE2D. A study reach with a length of 1.53 km from 7.785 to 9.31 km from El-Roda gauging station was selected. The pump station is located at 8.63 km from El-Roda gauging station. The study shows there is a significant morphological change in this reach due to the long study period and two hydraulic Structures (Imbaba and Rowd El-Farag Bridges). Moreover, the different alternatives for sediment control are discussed such as: dikes on the western side of the river at different locations or dredging the study area at different levels 14 and 12.5 (1 and 2.5 m respectively) below minimum water level. Finally, the research recommended the using 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.
