When water is released over chutes or spillways, potential energy becomes kinetic energy. It is necessary to discharge this energy to reduce the risk of serious erosion of the riverbed downstream and foundation deterioration, both of which might cause the spillway and dam to fall. Energy dissipators must be employed in order to accomplish this goal by first transforming the energy into a highly turbulent flow, then into thermal energy. To discharge surplus energy, a variety of methods can be used, including stilling basins. For example, creating a hydraulic leap in the stilling basin will do this. The calculation of the stilling basin inversion elevation in relation to the elevation of the upstream water, the design discharge, and the elevation of the downstream water and tail water is described in this study using a straightforward method. Very few examples are provided to demonstrate the design procedure’s possibilities.
