%X In this study, numerical simulation of flow over a chute spillway is presented using the computational fluid dynamics (CFD) method. The flow characteristics such as velocity, pressure and depth through the spillway have been calculated for four different flow rates. Since the actual flow is turbulent, the RNG turbulence model has been used for simulation. The numerical computed results of piezometric pressure and flow velocity along the spillway were compared with the results from the hydraulic model tests. The maximum difference between calculated and experiment results in average velocity values was 5.47 % and in piezometric pressure values was 7.97 %, and the numerical results agreed well with experiments.
