Abstract

A numerical model for wave refraction and diffraction has been used to compute irregular waves. The model is based on the parabolic approximation, but, by combining with the perfect boundary condition, it is suitable for waves propagating with large incident angles. The irregular waves are modelled through linear superposition ofwave components. In order to apply the model to field cases, however, the numerical computations were carried out with one representative frequency while retaining spectral representation of the directionality of waves. This approximation has been examined by the laboratory conditions of Vincent & Briggs; The model'sperformances in thefield cases were also investigated.
