Hydraulic Performance of a Moderately Sloped Stepped Spillway with 45-Degree Beveled Steps

Abstract

AbstractSpillways and overtopping protection of the downstream face of embankment dams have often used roller compacted concrete overlays, which commonly feature a beveled step to reduce the use of expensive formworks. This study experimentally ...Practical ApplicationsThis study investigates the hydraulic performance of beveled step spillways commonly constructed at embankment dams for overtopping protection. Key design parameters were quantified including flow bulking, chute water surface ...
