Enhancing flow pattern upstream of New Hafeer Pump Station

In the context of implementing and modifying pump stations, this study was commenced with the purpose of enhancing the flow pattern at their upstream. For that, a hydraulic study using fixed bed physical model was carried out to investigate the non-uniformity of flow distribution due to the formation of separation zone upstream of Lateral Pump Station (New Hafeer Pump Station). A new approach was investigated in the model to reduce the separation zones activity without any adverse impacts on the operation process. The approach is a combination of installing series of small Spur Dykes and Humps at the drain where the station is located. Four complementary modifications using the new approach were proposed and simulated. The results indicated the effectiveness of the investigated approach in eliminating the separation zone and hence improving the approach flow at the station entrance which makes the station units to withdraw regular and equal discharges.
