| Abstract: | In this paper, the Pade approximation of the 15th order Stokes wave is made use of to derive flow field eseentially consistent with experiments. Then we have calculated the force and the moment exerted by nonlinear periodic and breaking waves on the piles of various kinds. Their main characteristics are compared in details. The results seem to be useful for the design of offshore structures.In this paper, the Pade approximation of the 15th order Stokes wave is made use of to derive flow field eseentially consistent with experiments.
