Numerical investigation on the obliquely incident water wave passing through the submerged breakwater by singular boundary method

This short communication presents the Singular Boundary Method (SBM) to solve the obliquely incident water wave passing through the submerged breakwater. The SBM is a recent boundary-type collocation method with the merits of being meshless, integration-free, mathematically simple, easy-to-program, well suited for unbounded domain problems. The accuracy and efficiency of the SBM is first verified in several benchmark examples in comparison with the boundary element method. Then the effects of the position, size and geometry of the breakwater on water wave propagation are investigated through numerical experiments, and some new observations are concluded.
