The compacted spillway (CSW) refers to a spillway accompanied by jets located on its face to dissipate the excess energy. The (CSW) has a standard ogee profile with three jets located on the downstream face of the spillway. The jets are used to produce a reverse momentum which increases the rate of energy dissipation. Thus, the (CSW) greatly reduces the need for a large stilling basin. In this study, the characteristics of the flow over the (CSW) are investigated experimentally and theoretically.
