EROSION PROBLEMS OF THE DUTCH ISLAND OF GOEREE

H.G.H. ten Hoopen Krueger, W.T. Bakker

Abstract


At many places along the Dutch coast especially at the West side of the islands, erosion occurs. One of the islands where the erosion is severe, is Goeree, situated in the Delta area in the South-West of the Netherlands. (see fig. 1). This isle is recently connected with other islands by dams, (see fig.2). These dams built within the scope of the Delt aproject plans closing the tidal estuaries and to shorten the length of the coastline thus reducing the wave attack. This paper examines how the influences of the closure of the estuaries affect on the erosion of the neighbouring coast. To this end, the changes in vertical and horizontal tide caused by the closure as well as the wave induced littoral drift and the sand transport caused by a combination of tidal currents and waves before and after the closure, are computed. On the basis of this computations, a few suitable solutions for the reduction of erosion are discussed.
