Generalised hydrogeological map of Lower Saxony, 1 : 500 000 - Permeabilities of shallow rocks
(HUEK500DLOG)
The map shows the hydraulic conductivity of shallow rocks at a scale of 1 : 500 000.
The rock units in the 1 : 500 000 generalised geological map (GUEK500) are divided into three groups of hydraulic conductivity, delineated based on a rough estimate of the effective void space and adopting the information available from hydraulic investigations. This estimate is oriented around the rock mass hydraulic conductivity classifications as used by the state geological surveys' Arbeitsgruppe Hydrogeologie in their hydrogeological mapping guidelines (Hydrogeologische Kartieranleitung, Grimmelmann et al. 1997). The hydraulic conductivity coefficients are roughly allocated as follows:
- low hydraulic conductivity, corresponds to hydraulic conductivity coefficients kf < 1-10-5 [m/s];
- moderate hydraulic conductivity, corresponds to the range of hydraulic conductivity coefficients kf = 1-10-5 [m/s] to kf = 1-10-4 [m/s];
- high hydraulic conductivity, corresponds to hydraulic conductivity coefficients kf < 1-10-4 [m/s] and;
- highly variable hydraulic conductivity means that the respective rock complex has such variable properties that it cannot be clearly allocated to one group.
This map was created by re-attributing the contents of the 1 : 500 000 generalised geological map of Lower Saxony and therefore generally only covers a depth range down to approximately 2 m below grade.

- Information about data origin:
An Datengrundlagen sind eingegangen:
- Geologische Übersichtskarte 1:500 000
- Bohrungen der Bohrdatenbank Niedersachsen
- Bewertungsschema zur Durchlässigkeit von Gesteinen
Die hier vorliegende Karte entstand durch eine Umattributierung der Inhalte der Geologischen Übersichtskarte von Niedersachsen 1 : 500 000 und berücksichtigt somit in der Regel nur einen Tiefenbereich von ca. 2 m unter Geländeoberkante.
