LGRB-BW HK50: Hydrogeological units without top layers

The distribution of hydrogeological units is shown without superimposing on top layers (lower permeable, cohesive, predominantly quaternary and holocene lockersedimene). In addition, pore aquifers in the valleys of larger rivers were also covered (cf. geola_hyd_pgwl). The cover usually took place except for the top hydrogeological solid rock unit. In the foothills of the Alps, the holocene cohesive layers were removed, the glacial sediments were not taken into account. In the Upper Rhine trench, the top layers were removed except for the mighty quaternary pore aquifer.
