Description :
The sand movement on and around two barrier islands flanking the tidal flat area north of The Netherlands is studied by means of size, shape and density sorting. The coastline of the islands is still retreating. The removal of sand mainly occurs during storm surges. The eroded material is redeposited in sorted zones parallel to the coast. The coarset, most spherical and densest grains remain closest to the beach and can re-enter the beach as prograding bars during more quiet conditions. This process gives rise rive to a stepwise diminishing grain-size from island to island towards the east.
