The basic elements and characteristics of a hydraulic jump on horizontal aprons are provided to aid designers in selecting more practical basins. For preliminary designs, the estimating loss of energy can be determined as percentage of critical energy, Eq. The hydraulic jump problem can be solved by using momentum and specific energy equations which involve tedious methods of trial and error. In the present study, the side slope, the discharge and the energy loss in hydraulic jump in horizontal triangular section are known whereas one has to obtain the sequent depths.
