Description
Stepped Spillway Introduction
Stepped spillway is commonly used in reservoir dams in order to release flood safely. The stairs of spillway increase energy dissipation greatly. Stair spillways are among the hydraulic structures which attracted great interest to the designers due to their high water capacity energy dissipation. The flow mechanism is complicated in such structures, and more research is being done about it. For this reason, more research and simulation are needed to understand the fluid flow pattern correctly.
