Entrance to Upstream Approach Canal,Gainesville Lock, Tombigbee River,Mississippi and Alabama;Hydraulic Model Investigation.

摘要

As part of the program for the development of navigation on the Tennessee-Tombigbee Waterway, the Gainesville Lock and Dam will be the first navigation structure proposed for the development of the waterway. The lock will be in a bypass canal about 266 miles above the mouth of the Mobile River, which is at the foot of Government Street in Mobile, Alabama, or approximately 49 miles above the confluence of the Tombigbee and Warrior Rivers and 53 miles above Demopolis Lock and Dam. The structure is designed to maintain during low flows a minimum upper pool extending upstream to the proposed Aliceville Lock and Dam at mile 332.6. The project will include one lock with clear chamber dimensions of 110 by 600 ft located in a bypass canal on the left overbank and a dam consisting of a gated spillway and fixed overflow section.
