Influence of the wave period in the dune erosion model DUROSTA

The dune erosion prediction method presently used in the safety assessment of the Dutch dune coast was developed for situations with wave periods up to 12 seconds. New insights predict that situations with wave periods larger than 12 seconds can be expected. Preliminary analyses of the potential influence of larger wave periods on dune erosion...

The effect of wave period on dune erosion

Dune erosion is a relatively fast developing cross-shore transport process which occurs during severe wave attack combined with high water levels. Large quantities of sand coming from the dunes are transported seaward. If no seaward or lateral losses occur, the sand balance will be closed in cross-shore direction. The eroded sand will deposit on...
