The high energy of floodwater passing from a reservoir needs to be dissipated to prevent scouring and damage from the dam and other downstream structures. Hydraulic jump is a common way for this purpose. The description of the hydraulic jump has been extensively done using physical models. This study which applies the standard step method for computations of flow profiles accompanied with the Belanger equation, investigates locations of hydraulic jump for varied downstream conditions through the combination of different flow routings.
