Hydrogeology – A Consistent Basin-Wide Representation of the Major Aquifers in the Upper Danube Basin

• Modelling the changes of groundwater resources under conditions of global change is a crucial task in the UDC, where groundwater forms the main source of drinking water. The first step in the development of a numerical modelling of groundwater flow and storage changes is to develop a conceptual hydrogeological model that adequately represents the relevant geological and hydrological features of the model area. The large area of the UDC and the coarse resolution of the common DANUBIA model thereby demand strict simplification of the actual hydrogeological conditions. A central decision in this conceptualisation process is the definition of the major regional hydrogeological units to be considered by the model. This chapter describes the process of data collection, data homogenisation and aggregation into ten main hydrogeological units, called “base classes”. The properties and the relevance of these base classes for the numerical model are explained. The most important simplifications made are briefly discussed.
