چکیده مقاله:

Wave has been broken along the shores and causes changes in radiation stresses at the surf zone, as result, currents will be formed along the shore. This current and the resulted turbidity of broken wave are the most phenomena at the shore. In this study, using the continuity and momentum equations of shore’s current in the form of vector-conservation, the model of this current were introduced. The bed stress has been resulted at the presence of current and wave conditions, the vorticity viscosity as a function of wave energy dissipation in the surf zone and wave change using flux energy method has been calculated. The governing equation of continuity and momentum were solved by implicit F.D. method and discretized by linearization method. Finally, the results of numerical model and the Watanabe model were compared which show a good agreement for obliquely incident wave in steady-state conditions.
