Preliminary stage-discharge relations for Tombigbee River at Gainesville Dam, near Gainesville, Alabama
G. H. Nelson, C. O. Ming
1983, Open-File Report 83-942
The construction of Gainesville Dam and other related channel alterations, completed in 1979, has resulted in changes to the stage-discharge relations in the vicinity. The lack of current-meter measurements, coupled with backwater conditions, makes definition of a single stage-discharge relation impossible. However, limit curves can be defined that would encompass...
