An assumption of collinear straight coastlines in the far field, traditionally used in wave models for harbors, is a limitation to wave simulations in the domain extending to infinity, since this assumption is invalid for most real coastlines. By alleviating this limitation based on the geometric-optics approximation, functions of models for coastal wave-deformation are generalized to be able to predict wave patterns around the semi-infinite breakwater and convex and concave coasts, such as bulkheads with discontinuous alignment. Seven test problems of wave diffraction are solved by the finite element method based on the coastal wave-deformation models combined with the integrable, cubic infinite element. As a result of comparison with the analytical solutions, the generalized models are found to be effective and accurate for problems of wave scattering.
