FIELD AND LABORATORY VERIFICATION OF THE WAVE PROPAGATION MODEL CREDIZ

Resumen

Both the effects of refraction and diffraction may be efficiently modeled in wave propagation models by introduction of the parabolic approximation. The performance of the model CREDIZ, which is based on this parabolic approximation, was investigated in three verification studies. Two of these studies concern laboratory situations, i.e. one having a simple geometry and one having a more complicated geometry. The third study concerns a field situation, i.e. a shoal dominated area in an estuary mouth. It is found that despite the schematization to monochromatic, nearly linear wave propagation, the model CREDIZ performs remarkably well for engineering purposes.
