In this study, the effect of an end sill angle on the hydrodynamic parameters of a stilling basin, such as pressure, velocity, turbulence intensity, vorticity and energy dissipation, is investigated numerically. Simulations are performed using RNG and VOF for turbulence and free surface models, respectively. After verifying the numerical results with the experimental data, the effect of four end sill angles of 
, 
, 
and 
on the flow parameters in the stilling basin is analyzed. Results show that the stilling basin with triangle end sill with angle of has the best performance by dissipating 62% of energy.
