Abstarct: Hydraulic jump plays a significant role in dissipation of kinetic energy downstream of hydraulic structures in a stilling basin. Basin bottom roughness and reverse slope are the important factors for reducing length and secondary depth and increase of energy loss by hydraulic jump. In this study the effects of triangular roughness distance and reverse slope on hydraulic jump have been investigated experimentally and numerically. Experiments carried out a triangular rough bed with a distance of 0 and 2 cm, and three reverse slopes in a rectangular flume in a hydraulic laboratory of the Faculty of Agriculture, Shahrood University of Technology, Iran, Then experimental model was simulated by Fluent. The flume has 0.08 m wide, 0.3 m deep and 5 m long. In all experiments, the main characteristics of hydraulic jump including primary and secondary depth and the length of hydraulic jump were measured, also hydraulic parameters were determined as a function of the Froude number. 2D simulation was done by Fluent in two dimensions using standard k-ε RNG model. Comparing the final results showed that the secondary depth and hydraulic jump length on the rough bed with the reverse slope compared to the flat bed, decreased about 12 and 14 percent, respectively. Also the energy loss will increase and it will be intensified by increase of Froude number. Average of increase was about 13%. The non dimensional flow profile of hydraulic jump was uniform and showed a good agreement. The results showed that the CFD model used to predict the water surface profile in hydraulic jump was suitable on a triangular rough bed and the relative error of the water surface values obtained from the numerical and measured models is 2 up to 7 percent.
