Depth ratio of hydraulic jump in rectangular stilling basins

A theoretical prediction for computing the sequent depth ratio of the hydraulic jump formed in rectangular sloping and roughened stilling basins is developed. It is based on the application of the one-dimensional momentum and continuity equations. The derived equation contains two nondimensional experimental coefficients. one for the effect of slope and the other one for the effect of bed roughness. When the two coefficients are used together, the combined effect of both slope and roughness on the sequent depth ratio of the hydraulic jump can be computed. Experimental data verify the developed equation reasonably well.
