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

Abstract

A review of records and historical research of floods for the Tombigbee River near Cochrane, Alabama show that the flood of 1892 was the highest since 1818. In 1962 the U.S. Army Corps of Engineers estimated a peak discharge of 235,000 cubic feet per second for this flood-. This estimated discharge is more than 40 percent greater than the next highest flood peak; that of 1973. Limit curves have been developed for the tailwater of Alicevilie 'Lock and Dam. These limit curves, based on 61 computed discharges and 24 discharge measurements, show the range in stage for a given discharge at this site. Similarly, limit curves developed for Gainesville Lock and Dam pool were developed based on 49 computed discharges and 10 mean daily discharges. Data from hydrographic surveys that were made for more than 100 ranges in 1937 and 1971 are on file with the U.S. Army Corps of Engineers. Presently 49 sedimentation ranges between Alicevilie Lock and Dam and Gainesville Lock and Dam are surveyed routinely. Comparison of these and other data may be made to identify changes occurring along this reach of the river as a result of natural and man-made causes. This report presents a data base of these and other hydrologic data collected along the reach of the Torabigbee River between Alicevilie Lock and Dam and Gainesville Lock and Dam.
