Pond Creek Pumping Station, Southwestern Jefferson County, Kentucky; Hydraulic Model Investigation.
Abstract
A 1:20-scale pumping station model of the sump and gravity control, approach, stilling basin, and exit channel was used to investigate and develop a practical design that would provide satisfactory hydraulic performance. The pumping station and gravity control structures were combined by locating the gravity control below the sump. The pumping station consisted of four vertical pumps with a total capacity of 4,100 cfs. The gravity control section had a capacity for 17,000 cfs and consisted of an open-channel flow structure and tainter gate to maintain the pool. During operation of the pumps, surface vortices observed in the pump bays were eliminated by surface vortex suppressor beams. During operation of the gravity control structure, eddies and an unstable hydraulic jump observed in the stilling basin were eliminated by decreasing the rate of sidewall flare and strategically locating and increasing the height of the baffle blocks.
