Average Lowest Groundwater Level 2050
Description
This map shows the GLG results for future climate; in full 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 finely visualised with the Current Height Stock Netherlands, version 2 (AHN2). The result is a visualisation of the groundwater levels (meters below ground level) at 0.25 m², in which local altitudes become visible.
Construction
Broadly speaking, the build-up of the cards 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 computational 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 provides a refined image with a resolution of 0.5 by 0.5 meters. However, the calculation result is still based on the National Water Model with resolution of 250 by 250 meters. The operation therefore does not produce any additional calculation results, but the operation provides a useful map for climate sessions, as it is easy to interpret up to the plot level. The province accepts no liability for incorrect interpretation of the map. Source data and additional information on the National Water Model can be found at www.klimaateffectatlas.nl.
