Numerical Model Computing Wave Propagations in an Open Coast

Abstract

In this report, mathematical models, based on the parabolic approximation for computing ocean wave propagation, are presented. The theoretical background for the mild-slope assumption and the parabolic approximation is first summarized. Three different numerical models, using different coordinate systems, are then developed. These models calculate the combined wave refraction and diffraction over varying depth and current and in the vicinity of coastal structures. To verify the validity of the numerical models, numerical results are compared with laboratory and field data. Keywords: Coastlines, Inlets, Breakwaters, Submerged shoals. (kr)
