Rock-Lined Transitions; Hydraulic Model Investigation.

Abstract

Model investigations to determine the adequacy of the theoretical design of four rock-lined transitions in providing the desired boundary roughness for reducing velocities from supercritical (rapid) to subcritical (tranquil) are reported herein. Satisfactory design was developed for each project. Dumped-stone requirements in the transition were determined. The investigation of each rock-lined transition was concerned with its flow conditions in the approach channel, the performance of the energy dissipator, the adequacy of the boundary roughness, and the magnitude of scour in the earth channel downstream from the transition structure.
