Re-Aeration on Stepped Spillways with Special Consideration of Entrained and Entrapped Air

Re-Aeration on Stepped Spillways with Special Consideration of Entrained and Entrapped Air

As with most high-velocity free-surface flows, stepped spillway flows become self-aerated when the drop height exceeds a critical value. Due to the step-induced macro-roughness, the flow field becomes more turbulent than on a similar smooth-invert chute. For this reason, cascades are oftentimes used...
