| Description: | Technical Report Abstract: Physical models were used to evaluate the hydraulic performance of the Pointe Coupee pumping station sump and outlet structure. A sump design with umbrellas on the suction bells, converging sidewalls, and horizontal vortex suppressor beams provided satisfactory sump performance for pumps with low submergence. Approach channel modifications were found to have a negligible effect on sump performance. A stilling basin design with baffles and divider walls was developed. Riprap sizes were determined for the outlet channel downstream from the stilling basin. With the recommended designs, satisfactory hydraulic performance was achieved for the entire range of expected discharges, sump water-surface elevations, and tailwaters. A third model study of the Point Coupee siphon was also conducted and reported in WES Technical Report HL-82-21 dated September 1982. |
