Short Abstract: Storm erosion can radically change a coastal landscape and depends on the exposure of the coastline towards the orientation of storm landfall. A convex-shape coastline such as the North Sea coast of Sylt (North Frisian Wadden Sea) provides locally different orientations towards an approaching storm wave, and thus allows a systematic study of the alongshore impacts. A hybrid-approach of numerical modelling used Delft3D and XBeach to investigate the storm- and calm-event impacted beach and dune erosion. Predicted morphodynamics of both models have similar trends besides higher dune erosion in XBeach.
