The region of the "Donauried" (Danube reed) is located at the southern edge of the Swabian-Franconian Alb, Germany's largest karst aquifer system. From a hydrogeological point of view, the region is characterized by complex interactions between the regional Upper Jurassic karst aquifer, the alluvial aquifer of the Danube Valley with its range of reeds, the Danube River and the low-permeability formations of the Molasse zone. Especially the groundwater resources of the karst aquifer are used by numerous regional water-supply companies, which causes conflicts of interest concerning the management of surface water, groundwater and ecosystems.
The aim of the project is to develop a hydrogeological conceptual model of the karst aquifer system and to establish a regional water balance to provide a defensible scientific basis for sustainable groundwater management of the Donauried region.
