Abstract:

The Red River is a large alluvial river system with the lower 280 miles currently being developed for shallow draft navigation. The navigation project entails construction of five locks and dams, channel realignment, and bank stabilization works. The project features will be completed to allow navigation to Shreveport, Louisiana by early 1995. The Red River is heavily laden with sediments which are generally fine grained sands. The Red River has one of the highest sediment concentrations of all major rivers in the United States. Its sediment concentration is comparable to large rivers of the world in sediment concentration. Due to the amount and nature of sediment, the project features have incorporated management techniques to minimize the adverse impacts. The first two locks and dams constructed have been modified to reduce the sediment maintenance problems. Three remaining locks and dams were modified in design to improve the sediment management capability. Channel structures have been utilized effectively to minimize the need for maintenance dredging.
