文摘

Applying advanced features in the process-based model Delft3D results in an agreement with the observed initial morphological response of the Sand Engine with Brier Skill Scores in the ‘Excellent’ range. After the first year sand from the peninsular section has fed the adjacent coastlines up to 6 km. Erosion of the peninsular section shows a linear dependency on the cumulative wave energy densities of individual wave events. For the first-year response, milder wave events are equally important as the 12 largest storms. Erosion of the peninsular section is governed by waves and vertical tide, while tidal currents, surge and wind play a very minor role.
