Validation Test Report for the Coastal Wave Refraction and Diffraction Model.
Abstract
In coastal water, wave propagation is affected by many dynamic processes, including shoaling, refraction, diffraction, and energy dissipation. The existing RCPWAVE wave model in the Navy-Standard surf model was developed for open coast with slowly varying bathymetry. it cannot handle certain coastline configurations such as those that include islands and peninsulas. It also has a serious numerical instability problem. The more recently developed REF/DIFi wave model has a more robust formulation and does not suffer from the same limitations. In this report, a systematic set of tests was conducted to evaluate the REF/DIFi. The tests evaluate the shoaling and refraction, combined refraction and diffraction, energy dissipation, and wave-current interaction properties of the model. The model results were compared to analytic solutions from linear wave theory, laboratory and field data. REF/DIFi was found to perform adequately in all tests. The REF/DIFi has been integrated into the Navy-Standard surf model.
