Abstract

In the Netherlands much land was captured from the sea. At the same time however along the coast severe losses of land occurred. The main reasons were sea level rise and effects of decreasing tidal volumes of estuaries. Besides there were the local effects of shifting tidal channels and periodical movements of the coastline. Building of groynes, dune-foot revetments and dikes did not stop the loss of sand. On behalf of the increased interests in the coastal area the Dutch government decided in 1990 to stop the coastal erosion. The main measure to achieve this purpose will be artificial beach nourishment. This coastal defense method is in harmony with nature, flexible and cost-effective. This paper deals with the technical aspects of the new coastal policy.
