Design Wave Evaluation for Coastal Protection Structures in the Wadden Sea

The evaluation of design waves for coastal protection structures is enormously important for both the safety of the hinterland and economical use of public money. The recently gained advancements in mathematical modeling of waves allows its successful application even in areas with complex morphological structures like the Wadden Sea. A remaining major problem of coastal design wave modeling is still the evaluation of suitable boundary conditions for design conditions, particularly for offshore design waves. The following paper highlights procedures applied for the solutions of these problems in the Frisian Wadden Sea at the south North Sea coast which are partly also applicable at coastlines of any type.
