Impact of Converging Chute Walls for Roller Compacted Concrete Stepped Spillways

A study utilizing a three-dimensional, 1:22 scale, physical model was conducted to evaluate the flow characteristics in the spillway with varying training wall convergence angles. The wall height required to contain the flow for conditions tested varied from critical depth at a 15 degree convergence...

Summary:A study utilizing a three-dimensional, 1:22 scale, physical model was conducted to evaluate the flow characteristics in the spillway with varying training wall convergence angles. The wall height required to contain the flow for conditions tested varied from critical depth at a 15 degree convergence angle to three times the critical depth at a 52 degree convergence angle. The results of the study may be used to estimate minimum training wall height for conditions where bulking due to air entrainment may reasonably be neglected.
