Short summary
In this study, we examined regional differences in groundwater behavior in Berlin-Brandenburg. We have developed a novel approach, combining standard groundwater modelling tools such with special data analysis techniques. The presented methodology can help to separate areas with different groundwater behavior from each other, which could be used as a starting point for further analysis.
