            Abstract : 
The free surface flow around immersed bodies is a current CFD problem in applied fluid mechanics. The aim of this paper is to present a comparative study between experiments and numerical simulations of the flow around immersed bodies in vicinity of the free surface. The free surface flows in a planar channel were experimentally investigated in subcritical regim at Reynolds number Re = 3500, respectively Froude number Fr = 0.06. Numerical simulations are performed with the FLUENT code, RNG k-ε turbulent model and the volume of fluid (VOF) model for calculating the free surface geometry being used. The computational results showed a close agreement with experimental data obtained in the laboratory for the flow over the broad - crested weir with smooth and patterned surfaces.
