Spillway and Outlet Works, Rowlesburg Dam, Cheat River, West Virginia: Hydraulic Model Investigation

Abstract : Rowlesburg Dam will be a gravity-type concrete structure, 271 ft above the floor of the stilling basin and 1695 ft long. Flow regulation will be provided by a high overflow spillway consisting of seven 45-ft-wide bays and six 5-ft-8-in.-wide by 10-ft-high sluices with inverts 221 ft below the spillway crest. Tests were conducted on a 1:20-scale sluice intake model and a 1:60-scale comprehensive model to study hydraulic performance of the spillway, verify the adequacy of the spillway and sluices for both separate and combined-flow operation, verify and/or refine the stilling basin design, study approach and exit channel conditions, evaluate the effectiveness of the water-quality control tower and sluice in selectively withdrawing water from desired levels, and investigate pressures in the sluice intake.
