| Description: | Technical Report Abstract: This report describes a hydraulic model investigation of an existing pumping station and a 700-cfs-capacity pumping station proposed to provide additional flood protection for Drainage District No. 17, Mississippi County, Arkansas. A 1:12- scale model of the proposed pumping station, the existing pumping station, and the approach channel was used to determine flow patterns and velocities in the approach channel and to determine pressure fluctuations and vortex action within the pump sumps of the proposed station. The model investigation indicated a large eddy in the approach channel that caused air-entraining vortexes within the sumps and large pressure fluctuations at the pump intakes. These problems were relieved by adding an earth berm separating the two stations, round pier noses, and cylindrical quadrant walls at the proposed station, by raising the baffle wall behind the pumps at the proposed station, and by adding transverse, vertical baffle walls within the sumps in the proposed station. |
