Spillway for Belleville Locks and Dam, Ohio River, Ohio and West Virginia. Hydraulic Model Investigation.
Abstract
The spillway at Belleville Dam will consist of eight 110-ft-wide bays through which flow will be regulated by tainter gates. Energy dissipation will be accomplished in a stilling basin with a horizontal apron, baffle piers, and an end sill. Model investigations were conducted on a 1:36-scale section model which reproduced one central gate bay and approximately half of each adjacent gate bay. Tests were concerned with gate sill shape, stilling basin performance, and riprap requirements downstream from the stilling basin. Tests revealed that flow conditions were satisfactory for all partial gate openings with the original design gate sill shape. The original design stilling basin resulted in high bottom velocities in the exit channel which were reduced by lowering the elevation of the basin apron. The stability of a stone protection blanket placed on a 1-on-6 slope downstream from the end sill was determined. (Author)
