The groundwater contours of the main aquifer as well as the Panke Valley aquifer were calculated using an interpolation method (Point-Kriging). In order to gain information about the correlation of the spatial distribution and the groundwater level of the measurement points a variogram analysis was performed. For the groundwater level map of May 2018, for the first time, active wells of the Berliner Wasserbetriebe that pump from the main aquifer were taken into account. The status of the wells was set to active based on the recorded pumping volume. The water levels in the wells were derived from the surrounding observation wells.
The geostatistical parameters as a result of the variogram analysis for the main aquifer the Panke Valley aquifer are shown in Tab. 1.
