Kustgenese-2 ‘diepe vooroever’ : a description of the multibeam surveys 2017 and 2018

This report is part of the Kustgenese-2 programme “Diepere Vooroever”, which focuses on understanding the morphodynamics and sedimentology of the Dutch lower shoreface in order to sustainably manage the Dutch coastal system and keeping the coast safe. The goal of this research is to gain insight into the sedimentary built-up of the coast and which processes determine the exchange of sediment over the lower shoreface. To this end two multibeam surveys have been carried out in 2017 and 2018 at the study sites: Noordwijk, Terschelling and Ameland. By analysing the morphological features of the seabed, it is possible to understand the dominant marine processes during deposition and reworking of the sediment. Furthermore, the backscatter data were tested to their applicability for the lower shoreface.
