Abstract: Standardized designs for drainage structures in the Divide Cut Section of the Tennessee-Tombigbee Waterway were developed in model tests conducted on the USBR type VI impact basin at a scale of 1:4, on the minor drainage chutes and energy dissipators at a scale of 1:10, and on the major drainage structures at a scale of 1:25. Test results indicate that the type VI impact basin performs satisfactorily below rectangular channels for all discharges tested and critical dimensions are tabulated for discharges expected at drainage structures where the type VI basin will be installed. Generalized information was developed to permit satisfactory design of minor drainage chutes and energy dissipators emptying into the canal. A satisfactory baffled chute spillway was developed for the largest of the drainage structures. Model test results will permit design of the other three major structures based on a unit discharge of 60 cfs common to the five structures for 100-year frequency flows.
