Several existing numerical models for shallow water waves based on different wave theories were reviewed. Some wave energy conservation models for the forecasting of shallow water waves were analyzed, in which, the SWAN model, which makes use of the most advanced achievements of wave study and has been applied to several academic and realistic problems, was introduced here. The characteristics, capability, finite difference scheme of action balance equation of the SWAN model and its source term computing method were detailedly described. The model was applied to the problem of the wave propagation in a following and opposing current. Finally, the model was employed in the Haian bay area to simulating the wave heights and wave periods there, and the numerical results were compared with the observations.
