LGRB-BW HÜK350: Yield of hydrogeological units

In order to technically develop and use a groundwater deposit, it must have sufficient yield. This refers, on the one hand, to the long-term yield, which corresponds to the groundwater supply in the catchment area of the version, on the other hand, the technical yield, which is, to a large extent, a characteristic of the hydrogeological unit. The latter was primarily taken into account in the preparation of the yield card.
