Navigation Conditions at Columbus Lock and Dam, Tombigbee River, Mississippi and Alabama. Hydraulic Model Investigation.
Abstract
The Columbus Lock and Dam will be the third navigation structure proposed as part of the development of the Tennessee-Tombigbee Waterway for navigation. The structure will be located in a bypass canal about 370 miles above the mouth of the Mobile River at the foot of Government Street in Mobile, Alabama, or just downstream from the confluence of the Tombigbee and Tibbee Rivers and about 4 miles northwest of Columbus in Lowndes County, Mississippi. 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.
