Groundwater exploration, sustainable groundwater management, as well as the protection of this resource characterize essential aspects of hydrogeology. Besides the hydrochemical composition (qualitative) of the groundwater, this field of expertise also accounts for its subsurface flow characteristics (quantitative). With respect to this, it is indispensable to have the best knowledge possible about the structural conditions of the hydrogeological system.

Classical methodologies for system characterization are the analysis and integration of geological borehole data, geophysical measurements, remote sensing, laboratory experiments on representative field samples and hydrogeological field methods (pumping or infiltration tests) for the in-situ determination of related parameters.

The evaluation of hydrogeological systems is linked to site-specific monitoring programs and/or the use of multidimensional numerical flow and transport models. Depending on the issue involved, the models can be hydraulic, hydrochemical, or also thermodynamic, while corresponding model couplings are generally possible.
