Abstract

The growing awareness of climate change asks for innovation in the methods of applying nourishments at the Dutch coastline. The concept Zandwindmolen has therefore been developed. Using wind mills at sea, sediment is dredged offshore and transported towards the shore, from where hydrodynamic and morphodynamic processes redistribute sediment alongshore. A continuous supply of sediment is assumed. The physical behavior of the disposed sediment is yet unknown. Research has been performed to study the behavior of sediment around the nourishment location, as well as the effects on the initial behavior of the coastline. The research has given insight in the optimal depth, discharge rate and spreading configuration of a continuous nourishment, for which the longshore redistribution of sediment was the major requirement. These three boundary conditions have formed a basis for further research into this topic. The concept itself is feasible, as it shows desirable predictions of nourishment formation and coastal strengthening.
