| Abstract |
In 1990 the Dutch government decided that coastal erosion should be controlled using 'dynamic preservation' of the coastline. Five to seven million m3 of sand has been deposited along the Dutch coast as part of a beach nourishment programme. This adds a 'wearing layer' to absorb coastal energy so that the beach and dunes remain intact. The Netherlands now has over 20 years experience of sand replenishment. The management technique has many positive features and benefits. Sand replenishment may have ecological effects, however. This applies both to sand extraction sites at sea and to the nourishment site where the deposition of sand can have a direct effect on the benthos of the beach and the geomorphology of the beach and foredunes. In addition, anomalous wind-borne transport of replenishment sand can have an indirect effect on the geomorphology and vegetation of the outer dunes. |
