Dwelling times of leaching water in the unsaturated soil zone

The basis of this data set is the project on groundwater level 2013. The groundwater level was calculated in accordance with DIN 4049-3 from water levels of the active groundwater measuring points of the LfU as well as data from third parties from the cut-off date measurement of spring 2011. The dwell time of the leachate in the unsaturated soil zone according to DIN 19732 is based on the water content of the soil and is determined from the quotient of water content [mm] and leachate rate [mm/a]. For the point-wise calculations, approximately 50.000 holes were available, from which layer-related data were obtained. For the leachate rate, the rate of new groundwater from ArcEGMO for the period 1986-2005 has been taken as a basis. For the regionalisation, approximately 14.100 holes were used and these were carried out using Kriging Interpolation procedures. The resolution was carried out in a grid of 10x10 m. Calculated areas of < 25.000 m² have been entered into the enveloping area. Lakes with an area of < 25.000 m² have not been taken into account and have also been dissolved in the surrounding area. Open pits were cut out.
