Generally, the sedimentation in the forebay of pumping station may result in bad flow patterns, which will decrease efficiency of pump device and cause the vibration of pump house and units, or other safety problems. To research the improvement of this impact in an actual project, a physical model test was established for the original scheme of one pumping station. One part of results show that the flow velocity in the channel of regulating-pool is low under the high-water level condition, and

The final results show that this scheme could effectively increase the flow velocity at the bottom and reduce the sedimentation in the regulating-pool. Although the hydraulic loss of regulatingpool increased, it could be able to satisfy the design requirements.
