In this paper the WAM model is improved by considering the radiation stresses due to wave-current interactions in the spectral transport equation. The improved wave model is applied to compute wind waves in the Rhone river mouth area in the Southern France under various steady and homogeneous wind conditions. The aim of this study is to determine the wave conditions involved in the long-term evolution of the shoreline. From the numerical computation results, we can conclude that even for obliquely offshore wind conditions, alongshore waves exist in nearshore area and that the current due to the Rhone discharge has very little effect on the wave characteristics in relatively deep water.
