Abstract:

A study is reported herein of the performance of either an abrupt rise or a partial transverse sill as a part of a culvert energy dissipation scheme in which flow parallel to the culvert axis is transformed into supercritical radial flow. Energy dissipation is accomplished by means of a hydraulic jump which was formed as a result of the combined effect of radial flow and a transverse sill. A sill or an abrupt rise was introduced just downstream from the radial channel transition in .an effort to reduce the velocity of flow and impart stability of the jump position in addition to that provided by radial flow characteristics alone. Experimentation was carried out to determine the jump stability and velocity reduction achieved by means of the geometric configuration consisting of either a sill or a rise.
