This dataset was collected as part of the NWO-TTW project "Delta engineering - Drowning or Emerging (project no. 12431). This project and the fieldwork was facilitated by Staatsbosbeheer. For this project we take advantage of a recently opened tidal freshwater system to study the sediment deposition or erosion in newly created tidal wetlands. Therefore, we quantified both the magnitude and spatial patterns of sedimentation and erosion in the former polder area “Kleine Noordwaard”, a freshwater tidal wetland In the Rhine-Meuse delta, the Netherlands. Water and sediment have been reintroduced in this area since 2008. Based on terrestrial and bathymetric elevation data, supplemented with field observations of the location and height of cut banks and the thickness of the newly deposited layer of sediment, we determined the sediment budget of the study area for the period 2008–2015. For this, we used the data from this dataset, which comprises: 1) the difference in channel bed level for each monitoring period, 2) the initial digital elevation model of the study area, 3) the locations of the inlet, center, and outlet as used for the subdivision of the study area, 4) the location of the dredged area, 5) the total sedimentation as measured at the intertidal flats, and 6) the location and height of cut banks, observed in the study area. The initial digital elevation model of the study area comprises the digital height model of the Netherlands (Actueel Hoogtebestand Nederland), supplied with the Channel bed elevation of 2009. Channel bed elevation was measured by Rijkswaterstaat during consecutive bathymetric surveys for the years 2009-2015. Sedimentation on top of the former polder soil of the intertidal flats was measured using Transparent Perspex core samplers during field campaigns in July and October 2014. The former polder soil consists of a compact non-erodible layer of clay, which was used as marker horizon. Furthermore, we measured the height and position of cut banks using a ruler and a Trimble R8 RTK GPS during field campaigns in July and October 2014.
