Kustgenese 2.0 : available measurements and bathymetric data at Ameland inlet, The Netherlands

This report provides an overview and analysis of available bathymetric and hydrodynamic data of Ameland inlet in the Netherlands. Twelve OEMs of the complete inlet system (ebbtidal delta, basin and inlet) and eight OEMs covering the ebb-tidal delta only were constructed based on data in Vaklodingen format (sources: regular Vaklodingen, SBW and Kustgenese 2.0). Additional yearly bathymetric maps of the nearshore (Jarkus), and high-resolution multibeam data in Borndiep, suitable for bedform analysis, are presented. Tides, wind and wave data are measured at various locations throughout the Wadden Sea and neighbouring North-sea. Most relevant for Ameland are water levels measurements at the stations Texel Noordzee, Wierumergronden, Nes arid Holwerd. The long-term records of the SON (Schiermonnikoog) wave buoy correlate best to the local (SBW) wave measurements at Ameland. SBW data at 12 stations in the inlet are measured during the stormy season (September - April). Only limited measurements of flow and discharges are obtained. Discharges were only found in reports that provide the cross-section averaged results. ADCP flow measurements were obtained for 3 locations on the ebb-tidal delta (2007-2008 time frame). Spatially coherent flow and wave data over the inlet domain can be retrieved by the XBand radar and XMFit software.
