Outlet Works Stilling Basin for Texarkana Dam, Sulphur River, Texas: Hydraulic Model Investigation
Abstract
The outlet works stilling basin for Texarkana Dam was studied on a 1:25-scale model to insure adequacy of the basin in reducing the velocity of flow issuing from the twin conduits. Initial tests indicated the necessity for revision of various stilling basin elements. Energy of flow from the conduits operating singly, or in combination, was not diminished as the flow passed through the stilling basin. Flow concentrated in areas adjacent to the splitter wall and had upstream direction adjacent to the outside basin walls. The desired performance of the stilling basin was secured by use of warped transition sections downstream from the conduit exit portals, elimination of the stepped apron, and reduction of 3 ft in the height of the splitter wall. The elevation of the stilling basin and height of end sill were not changed.
