Chapter 13 describes testing of two wave refraction models. The first is based on a parabolic approximation method, using a finite difference technique which includes the effects of combined refraction/diffraction, nonlinear effects, wave breaking and wave/current interaction. The second model is simpler and based on the wave action equations. It includes the effects of wave refraction, shoaling, partial wave breaking and bottom friction. Describes tests against laboratory wave data, hypothetical bathymetries and field data. Discusses results obtained for the first (parabolic) model (REF/DIF 1) and the second model (REFRACT). The first is good for areas where combined refraction/diffraction effects are important, but is expensive to run. The second model is useful for areas with larger length dimensions, though energy dissipation effects are better modelled by REF/DIF 1.
