Lines of equal groundwater head in aquifer 1. Represented in meters in relation to NAP, 25 cm away. Average situation period 2009 - 2020.

The groundwater levels from the soil map of the Netherlands were updated in 2005. The new groundwater levels are divided into 11 classes. The map scale is 1 : 25 000.

Lines of equal groundwater head in aquifer 1B. Displayed in meters relative to NAP, 25 cm away. Dry situation period 2009 - 2020.

Average amount of vertical seepage of groundwater on 1 April at a depth of a few meters below ground level in millimeters per day. The seepage was calculated with the regional...

Locations of drillings where no boulder clay has been found in Drenthe.

Gives the locations of the measuring points of the primary measuring network for groundwater levels.

The map shows the average amount of vertical seepage of groundwater on 1 October at a depth of a few meters below ground level in millimeters per day. The seepage was calculated...

This file contains the calculated average seepage in mm/day over the period 2012 to 2019

The average groundwater level in spring. This is also referred to as Average Spring Groundwater Level (GVG). The value of the groundwater level is measured in the field in...

This file contains the calculated average groundwater level over model year 2012 up to and including 2019 compared to NAP.

Lowest sectoral desired groundwater level (current situation).

Lines of equal groundwater head in aquifer 1. Represented in meters in relation to NAP, 25 cm away. Dry situation period 2009 - 2020.

The file shows the groundwater level in the province of North Brabant, based on the median of the GHG and GLG.

This file contains the difference in calculated wet damage for agriculture per building block. The difference is calculated between a building block and the reference situation....

Lowest reference groundwater level derived on the basis of AHN and the Soil Map.

Thickness of the boulder clay package in Drenthe, in metres.

Hydraulic resistance (c-value), in days, of boulder clay in Drenthe. This is a measure of the resistance this layer offers to vertical groundwater flow.

Lowest sectoral desired groundwater level (EHS achieved).

Potential for wet nature. Low rewetting means that the GVG must be increased to 50 cm or the drought stress must be limited to 9 days. A lot of wetting means that the GVG must...

This file contains the calculated average seepage in mm/day over model year 2012 up to and including 2019, including the effects of the KNMI WH scenario up to 2050.
