TL;DR: In this paper, an exact solution for diffraction of short-crested waves incident on a circular cylinder is presented, and the wave load increases as the wave number in the direction perpendicular to the direction of the wave propagation increases, or as the incident waves become shorter.

TL;DR: In this paper, the wave loads induced by short-crested incident waves on a vertical cylinder of arbitrary cross-section are discussed and it is shown that for a cylinder of a certain cross-sectional area, wave loads can be larger than those induced by plane waves with the same total wave number.

TL;DR: In this paper, the scaling boundary element method (SBFEM) was used to solve the boundary value problem composed of short-crested waves diffracted by a vertical circular cylinder.
Abstract: 7 The scaled boundary finite-element method (SBFEM) is a novel semi-analytical method 8 developed in the elasto-statics and elasto-dynamics areas that has the advantages of com- 9 bining the finite-element method with the boundary-element method. The SBFEM method 10 weakens the governing differential equation in the circumferential direction and solves the 11 weakened equation analytically in the radial direction. It has the inherent advantage of 12 solving the unbounded fluid dynamic problem. In this paper, the boundary-value problem 13 composed of short-crested waves diffracted by a vertical circular cylinder is solved by 14 SBFEM. Only the cylinder boundary is discretized with curved surface finite-elements on 15 the circumference of the cylinder, while the radial differential equation is solved completely 16 analytically. The computation of the diffraction force based on the present SBFEM solu- 17 tion demonstrates a high accuracy achieved with a small number of surface finite-elements.

TL;DR: In this paper, a quantitative understanding of the forces developed by wave action against circular piling is presented, where the authors focus on the effect of wave action on circular piling and show that wave action is a powerful force against piling.
Abstract: : Although circular piling is a much-used structural element in shore protection, harbor, and other maritime structures, only recently have significant advances been made toward gaining a quantitative understanding of the forces developed by wave action against piling. The present report deals with this subject.

TL;DR: In this article, the heights and phase relationships of non-breaking ocean waves about a cylindrical island were shown by a model study to be in agreement with the corresponding diffraction theory, and the variation of pressure with depth was found to be more rapid than the hyperbolic cosine variation which has been used for forces on piling.
Abstract: The heights and phase relationships of non-breaking ocean waves about a cylindrical island were shown by a model study to be in agreement with the corresponding diffraction theory. The variation of pressure with depth, however, was found to be more rapid than the hyperbolic cosine variation which has been used for forces on piling.
