Climate Atlas — Theme Dry — Average Lowest Groundwater Level 2050 — Scenario Low

This map shows the GLG results for future climate; the Average Lowest Groundwater Levels (GLG) of the National Water Model (results September 2017) for future climate (KNMI climate scenario WH2050). The groundwater levels have been refinedly visualised with the Current Height File Netherlands, version 2 (AHN2). The result is a visualisation of groundwater levels (meters below ground level) at 0.25 m², in which local altitudes become visible. Build-up In general, the structure of the maps is as follows: » Use of grid with calculation result GLG for climate scenario WH2050 (National Water Model, resolution 250 by 250 meters); » Spatial interpolation of these results for the creation of smooth transitions between the calculation cells of the NWM; » Processing with the AHN2 (resolution 0.5 by 0.5 meters) to groundwater levels below ground level. Accountability In the maps, additional information is generated by interpolation and combination with the AHN2. This delivers a sophisticated image with a resolution of 0.5 by 0.5 meters. However, the calculation result is still based on the National Water Model with a resolution of 250 by 250 meters. The operation therefore does not provide any additional calculation results. However, the operation provides a usable map for climate sessions, as it is easy to interpret down to the plot level. The province accepts no liability for incorrect interpretation of the card.
