摘要

The large influence of the Wadden Sea on the sediment budget of the Dutch coast is well known and seen as one of the reasons behind its structural erosion. Between 1933 and 2015, 367 million m3 (mcm) of sediment was deposited in the Western Wadden Sea. Corrected for sand mining, dredging and dumping these volumes increase to 438 mcm. The largest changes occur in the basins of Texel Inlet and Vlie Inlet with increases in sediment volume of 272 mcm and 133 mcm respectively. Through the construction of a high-resolution sediment budget model we can estimate that the long-term accretional trend is 5.4 mcm/year. However, the present-day sediment import has reduced to 0.75 mcm/year. These significantly reduced import rates may have important implications for the future management of the Wadden Sea and its adjacent coastline.
