Streamflow and cross-section data for the Tombigbee River between Gainesville and Demopolis locks and dams

Abstract

A review of records and historical research of floods indicate that the flood of April .15 through 18, 1979 was the highest recorded this century along the reach of the Torabigbee River that is now bounded upstream by Gainesville Lock and Dam and downstream by Demopolis Lock and Dam. The peak discharge at Epes was 247,000 cubic feet per second and 343,000 cubic feet per second at Demopolis Lock and Dam. Limit curves have been developed for the tailwater section of Gainesville Dam. These limit curves, based on 105 computed discharges for four floods since April 1979, show a range in' stage for a given discharge. Data from hydrographic surveys that were made for more than 100 sedimentation ranges in 1971 are on file with the U.S. Army Corps of Engineers, Mobile District. Presently 42 sedimentation ranges are surveyed routinely between Gainesville Lock and Dam and Demopolis Lock and Dam. A comparison of these and other data may be made to identify possible changes that have occurred. This report presents a data base of these and other hydrologic data collected along the reach of the Tombigbee River between Gainesville Lock and Dam and Demopolis Lock and Dam.
