LGRB-BW Potentially reduced protective function due to karting hazard

In areas with risk of karstisation, the protective function of groundwater cover may be significantly lower due to karst structures than determined by the Hölting method used. The present data set does not distinguish which rocks (sulfate and/or carbonate rocks) may have possible karst phenomena. In areas without a geological 3D model, roughly areas where karstisation is possible are additionally endured.
