Abstract: Energy dissipation downstream of spillway is one of the most challenging jobs in the design of a dam. With the past experience it is now observed that the hydraulic jump type energy dissipator is the most efficient and reliable divice. However its performance depends on a number of factors. The important being the tail water rating curve. If the tail water level matches with the water level after jump for all the discharges then the energy dissipation in the stilling basin is quite satisfactory. Efforts are made in this article to evaluate the range of tail water parameters so that the tail water level matches with the water level after jump for all the discharges.
