Abstract
The current safety criteria for a dam focus on protecting the dam especially during a large flood heavy rainfall event. Energy dissipator is a device designed to protect downstream areas from erosion by minimizing the flow velocity up to an acceptable limit. It is an important element of hydraulic structures as a transition between the high-velocity flow and the sensitive tailwater. This paper reviews energy dissipaters in connection with dam and spillway structure. This paper also describes the different types of energy dissipators with different appurtenances used in hydraulic structures for protection work. It includes topics such as energy dissipation of block ramp, hydraulic jump type stilling basin, stepped spillway, and the deflector (flip bucket and ski-jump bucket). � 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
