| Abstract |
Beach erosion occurs along a large part of the Belgian coast but is often more intense at Knokke coastal zone. Artificial nourishment of the active beach system is one of the most applied and successful measures to prevent and to cope with erosion. After repeated beach nourishments over the past decades, a major scheme is now being implemented: a combined large beach and nearshore nourishment of a total of 3.4 million m3 of sand for the Knokke area in the period 2020 – 2024. The aim of this study is to understand the hydrodynamics and morphodynamics of the Knokke area and to evaluate the effect of the beach and nearshore nourishments. This 5th year and final report focuses on coastal morphological changes along the east Belgian coast from Zeebrugge to east of the Zwin between 2018 and 2024. The results clearly indicate the significant effect of the nourishments on the beach and shoreface morphology as well as the spatial spreading of sand over time driven by tidal and wave currents. The continued topo-bathymetric surveys in the coming years will allow to monitor the further evolution of the large nearshore nourishment. |
