Yazoo Backwater Pumping Station Discharge Outlet

The 1:24-scale physical model investigation of the discharge outlet of the Yazoo Backwater pumping station, west-central Mississippi, was conducted to give a three-dimensional analysis of the proposed outlet structure and channel. The model evaluated flow patterns for different operating conditions and channel stability. Model tests that the original apron could be shortened with the addition of an end sill. Riprap protection remained stable, providing a stable channel for all conditions tested. The effects of a shutter gate on the velocities in the outlet channel were identified.
