Deltares report. Annual sand nourishment operations maintain the coast line and supplement the coastal foundation so that it can match sea-level rise. In practice, the dunes are the least active part of the coastal foundation, mainly as a result of foredune management, which interferes with sand transport to the dunes in many locations. Allowing sand to drift into the foredune where possible will allow the dunes to re-acquire an active role in the coastal foundation and therefore match sea-level rise.
