Spillway for Burnsville Dam, Little Kanawha River, West Virginia, Hydraulic Model Investigation.

Pagination or Media Count:
The concrete gravity ogee spillway for the Burnsville Dam will contain three 42-ft-wide gate bays separated by 8-ft-wide piers. Outlet works consisting of five low-level and three water-quality sluices will discharge on the downstream slope of the spillway. A hydraulic-jump type stilling basin will provide satisfactory dissipation of the energy of the spillway and sluice flows. A 140-scale model of the spillway, sluices, stilling basin, approach area, and exit channel was used to study the overall hydraulic performance of the structure. Tests indicated that flow conditions in the approach to the spillway with both uncontrolled and controlled flows were satisfactory for the full range of anticipated discharges.
