Figure 1: Elevation maps of the Perkpolder tidal basin, T-1 (December 2013), T0 (June 2015), and T4+stick (April 2016) (Boersema et al. 2016).
The maps in figure 1 show the surface levels at various moments in time, in December 2013 (T-1), June 2015 (T0), and April 2016 (T4 + stick). The last map is a composite of T4 multi-beam data, LiDAR measurements and the bamboo stick measurements. The hypsometric curves (figure 2) show the changes in the surface level. The differences between T-1 and T0 are due to excavation work of the contractor. The top layer of the surface was removed, a pond in the northern part was created including creeks in the south. After opening most of the changes are visible in the lower part of the hypsometric curves. This is caused by the large sedimentation in the pond and the sedimentation at the creek bedding around -1,0 m NAP .
Figure 2: Hypsometric curves of the Perkpolder tidal basin T-1 (Dec. 2013), T0 (June 2015), and T4+stick (April 2016). On the y-axis the surface elevation, on the horizontal axis the ratio a/A, where ‘a’ is the area below a given elevation contour, and ‘A’ is the total basin area (Boersema et al. 2016).
