For the practical application in coastal engineering, the universal model of water wave, momentum conservation and energy conservation equation with considering of energy loss due to bottom friction and wave breaking is adopted in this paper to evaluate the wave transformation on general slope, which including wave shoaling, breaking and attenuation after breaking as well as wave set-up and set-down during the waves advancing toward the coast. In comparison with the results of theoretical approaches as well as experimental data accomplished by the traditional method, very good coincidence is obtained besides the mean sea level variation.
