Parabolic Wave Computations in Non‐Orthogonal Coordinate Systems

Abstract

A recent development of a parabolic equation method for wave propagation in a non‐orthogonal coordinate system is reviewed. A transformation of the full governing equation prior to development of any approximation leads to a model whose results stand in closer agreement to laboratory data for a case of waves propagating into a breakwater harbor. The effect of amplitude dispersion on predicted wave height is studied and is also seen to be important for the case considered here. Reflection of obliquely incident waves by a vertical wall is also considered.
