Abstract

The parabolic approximation is developed to study the combined refraction/diffraction of weakly nonlinear shallow water waves. Two methods of approach are taken. In the first method Boussinesq equations are used to derive evolution equations for spectral wave components in a slowly varying two dimensional domain. The second method modifies the equation of Kadomtsev and Petviashvili to include numerical results, experimental data and previous numerical calculations. The parabolic equation method appears satisfactory. (A)
