Abstract: Conventional methods of energy dissipation by single-fall hydraulic jump-type stilling basin, roller bucket, or ski-jumpbucket may not be suitable for high dam spillways be-cause of very high velocity at the end of the spillways, niadc-quatc tailwater depthw, or Side Coditions. A suitable spillway alternative can be a cascade of falls with a still-ingbasin below each fall. This paper presents a computing method for the design of cascade stilling basins for high dam spillways. The design is demenstrated by a numcrical example.
