Radial Flow Energy Dissipator for Culvert Outlets

摘要

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 seperation form 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. (Author)
