Abstract:

A model study was performed on a new type of energy dissipator for culvert flow. In this structure, the culvert flow drops along a steep chute, which ends at its intersection with the horizontal bottom of the stilling basin. As the flow impinges on the horizontal bottom, it is caused to spread rapidly, thus avoiding separation from the flared wingwalls. At the same time, the flow is changed from parallel to radial flow, and again to parallel flow in the downstream channel. The combination of this supercritical radial flow and the required tailwater depth results in the formation of a hydraulic jump whose leading edge occurs along a circular arc, thus it is referred to as a circular hydraulic jump. The required tailwater for such a hydraulic jump admits substantial variations while the position of the jump itself is varied by a relatively short distance.
