A Hybrid Approach to Improve Energy Dissipation in Stilling Basin

Abstract

Abstract: This study contains a hydraulic prototype model and experiments that will be conducted to generalize and prove the hydraulic design of a new type of stilling basin that controls discharge with a hollow-jet valve. The stilling basin is usually considered to be the most efficient hydraulic structure for dissipating flow energy. The size and shape of the stilling basin affect the formation of flow patterns, which can affect the overall hydraulic performance of the system. An ogee spillway's is important for dissipating excess water's specific energy. The kinetic energy generated by the release of water from the top to the toe of the spillway is considerable. This will cause scour and erosion on the downstream face of the spillway. The above problems are going to be solve by developing a workable physical model for an ogee spillway that considers the combined impacts of steps, roller buckets and USBR Stilling basin.
