NAVIGATION CONDITIONS AT COLUMBUS LOCK AND DAM, TOMBIGBEE RIVER, MISSISSIPPI AND ALABAMA. HYDRAULIC MODEL INVESTIGATION

The structure is designed to maintain a minimum upper pool during low flows extending upstream to the proposed Aberdeen Lock and Dam at mile 408 and will include one lock with clear chamber dimensions of 110 by 600 ft, a five-gate spillway section of the dam located in the bypass canal on the left overbank, and a fixed overflow section along the left overbank to high ground. A fixed-bed model reproducing about 4.5 miles of the Tombigbee River channel, upper and lower lock approaches, the lock approach canal, and the adjacent overbank areas to an undistorted scale of 1:120 was used to determine the adequacy of the proposed plan and to develop modifications required to eliminate any adverse conditions indicated. The model investigation was concerned principally with navigation conditions into and within the lock approach canal and in the lock approaches and the distribution of flow through the gated section of the dam.
