AbstractAn evolution equation is developed from the mild slope equation by using the perturbation method. For large times the solutions of the model will approach results of the elliptic mild slope equation. The alternating direction implicit method is used to solve the equation and the numerical scheme is unconditional stable. Another model based on wave amplitude and phase function is derived straight-forward from the time dependent parabolic model and it can be applied to a large area. Experimental data obtained by Berkhoff et al. (1982) are used to test the model. Comparison of the present model results for the case of an elliptic shoal against the Generalized Conjugate Gradient model results has been made and good agreement has been achieved.
