| Abstract: | Using the spectral method presented by 1], the diffraction of a solitary wave around large vertical cylinder is investigated by solving the Boussinesq equations which are expressed by depth-averaged velocity potential. The wave force coefficient exerted on cylinder is obtained by means of numerical method and the influence of depth variations on the force coefficient is discussed in this paper. |
