DISCUSSION The creation of an elevated artificial coastline with dredged seabed material has led to surface armoring which affects the total amount of wind-driven sand supply to the dunes [2]. The location of the lake and lagoon, combined with directional properties of the wind climate, steer an alongshore varying aeolian sediment supply towards the dunes. Potentially, the incipient hummocky dunes may also become a sediment sink area and as such modulate sand supply to the foredunes. The locations of new dune formation away from the primary dune foot are strongly tied to establishment of vegetation which is linked to the design property ‘elevation’as this influences frequency of flooding [3]. Also prevailing management practice regarding beach raking, allowed beach traffic, and fencing off of areas with incipient dune formation influenced vegetation establishment.
