Groundwater equal plan

The groundwater equal plan describes the large-scale flow directions and gradient conditions of the groundwater by means of the representation of the groundwater pressure area in lines of the same height (isohyps in [m ü NN]). Essentially, the groundwater isohyps for the upper main aquifer are provided here. In addition, the map provides indications of smear areas of the main aquifer, geological disturbances, stream dips, groundwater sheds, and artesian groundwater conditions.
