Abstract

Abstract

In order to ensure the stability of the beach and coast, three times of shoreface nourishments(1998, 2002 and 2006) have been launched in the Noordwijk, the Netherlands. There are double subtidal bars developed in the study area. For three times, sands are nourished on the seaward side of the outer bar, which is close to the local closure depth. The shoreface nourishment reduced seaward migration rates of the bar. Both the inner and outer bars show a trend of onshore migration and remain stable，which has a positive effect on the shoreline stability. Facts prove that shoreface nourishment may resist against coastal erosion and keep the beach stable by increasing wave dissipation and keeping the nourished sands moving onshore. At present, most of the beach protection projects in China are dominated by beach nourishment, which are economically expensive, environmentally destructive and ineffective, while the shoreface nourishment has the advantages of economy, small impact on the environment and flexibility. We should make full use of the successful experience of shoreface nourishment. In this paper the effects of shoreface nourishments of Noordwijk is studied and analyzed based on Argus video images and bathymetric data. And the significance of shoreface nourishment is summarized to enrich and promote the development of coastal management.
