Deeper, tertiary aquifers
The map shows the Tertiary aquifers found beneath the glacial sedimentary sequence with a main separating layer in between. In all cases, these are loose rocks. With the... -
Groundwater recharge during the dry period (1971-1973)
Groundwater recharge from precipitation is a residual component of the water balance. It is described as the proportion of precipitation total reduced by actual evaporation and... -
Hydrostratigraphy of the cohesive surface layers
The map shows the chronological classification of the cohesive layers of the covered, near-surface aquifer. Including slight sand deposits, the thickness range of at least 5 to... -
Protective effect of the top layers on the surface
The card contains an evaluation of the protective effect of the top layers, divided into the three categories "unfavourable", "medium" and "favourable". The decisive criterion... -
Hydrogeological profile types of the deeper Tertiary aquifers

Hydrostratigraphy of the covered, near-surface aquifer
The map shows the temporal grading of the sands of the shallow covered aquifer. These sands contain parts from all three known glaciation periods in Schleswig-Holstein -
Groundwater recharge during the wet period (1979-1981)
The groundwater recharge rates shown on the map are the result of modeling with qualitatively different input data. In each case, the best data basis available throughout... -
Mean groundwater recharge from precipitation (1971-2000)
