Abstract : A 1:10-scale hydraulic model study was conducted to investigate performance of the original design pumping station sump and, if necessary, develop modifications required to provide satisfactory flow to the pump intakes. Satisfactory sump performance was indicated for all anticipated water-surface elevations with either single or multiple pump operations. Adverse sump performance was not evident until the water surface was lowered 3 ft below the minimum anticipated. The model indicated that the approach wing walls to the sump could be constructed of either sheet piling or concrete as originally designed. The size and extent of approach channel riprap protection required for stability with all anticipated flow conditions were also determined. (Author)
