Energy Dissipation for a RCC Stepped Spillway

by Charles E. Rice, United States Dep of Agriculture, Stillwater, United States,
Kem C. Kadavy, United States Dep of Agriculture, Stillwater, United States,



Document Type: Proceeding Paper

Part of: Hydraulic Engineering

Abstract:

A two-dimensional physical model study was used to quantify the kinetic energy dissipation of the steps in a roller compacted concrete (RCC) stepped spillway. The steps were effective in dissipating energy and significantly reduced the size of stilling basin required at the toe of the spillway compared with a conventional chute spillway.
