【 摘 要 】

A method simply treating the governing equation for Z-D wave-motion is proposed in this paper. The Enter's velocity in whole depth can be directly calculated with this method if the wave free surface is given. For the linear waves the wave surface is determined from given directional spectrum (.Yu. et al. 1991) or other wave surfaces at near locations with an inversion method proposed in this paper. For the nonlinear waves the wave surface can be determined with the method proposed by Dommermuth and Yue (1987). These methods proposed by authors are tested and verified •with numerical simulation > model test or field observation data.
