Abstract: Hydraulic jump is one subject which has extensively been studied in the field of hydraulic engineering. It is the most frequently encountered cases of rapidly varied flow in hydraulic engineering. Hydraulic jump occurs when a supercritical flow meets with subcritical stream of sufficient depth. Hydraulic jumps have been widely used for energy dissipation below hydraulic structures. This study concerns with the investigations of effects of channel slopes and channel bed roughness height on hydraulic characteristics. To achieve this purpose the bed of flume was provided roughness of different size of gravels (d50= 0.010m, 0.012m, 0.015m, 0.017m) and three different channels slopes (0.0115, 0.0146, 0.0174) were used. In all 48 different runs were conducted with varying discharge and approach supercritical flow depth. The available empirical relationships for estimating the sequent depth ratio were first checked for their accuracy for new data. As the existing relationships were inadequate, new relationship are proposed herein for parameter of the hydraulic jump. Comparison of observed values of sequent depth ratio with calculating values coming from respective proposed relationship showed satisfactory agreement
