RADIAL FLOW ENERGY DISSIPATOR FOR CULVERT OUTLETS

A NEW TYPE OF ENERGY DISSIPATOR FOR CULVERTS LOCATED IN CHANNELS OF STEEP SLOPE WAS INVESTIGATED BY A MODEL STUDY AND AN EVALUATION OF THE STABILITY OF THE HYDRAULIC JUMP AS INFLUENCED BY THE BASIN GEOMETRY AND TAILWATER DEPTHS. THE DESIGN INVOLVES A CONCENTRATION OF A PART OF THE FALL OVER THE LENGTH OF THE CULVERT INTO A STEEP, CURVED CHUTE AT THE OUTLET, TERMINATING AT A HORIZONTAL BOTTOM BASIN BOUNDED BY FLARED WALLS AT EACH SIDE. AS THE FLOW IMPINGES ON THE BOTTOM, THE RESULTING PRESSURE CAUSES A CHANGE TO RADIAL FLOW, WHICH IS REDIRECTED BY THE SIDE WALLS TO PARALLEL FLOW IN THE OUTLET CHANNEL. A HYDRAULIC JUMP WILL BE FORMED WITHIN THE RADIAL FLOW BASIN BY VERY LIMITED DEPTHS OF TAILWATER. FURTHER DEVELOPMENT OF DESIGN CRITERIA WILL BE NECESSARY. /BPR/
