Research Study on Stilling Basins, Energy Dissipators, and Associated Appurtenances, Section 13. Stilling Basins for High Head Outlet Works with Slide-Gate Control (Preliminary Studies)

摘要

The purpose of these studies was to develop an efficient, economical stilling basin for use with slide gate control for high-head outlet works. Design curves were developed for a rectangular plunge basin to determine basin depth and length, height of the gate above the basin floor, and magnitude of impact heads on the basin floor. Comparisons were made with corresponding basins of the hydraulic jump type designed according to Engineering Monograph 25. Tentative design curves were obtained for the hydraulic jump basin based on data derived from general model studies of four particular stilling basins. Recommendations for continuing work in this study are presented. (Author)
