Groundwater exploration, a sustainable groundwater management as well as the protection of this resource characterize essential aspects in
the subject 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 indispensible 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.

An effective and sustainable groundwater management demands interdisciplinary approaches and specified solution strategies. In most cases, natural conditions interact with anthropological aspects such as drinking water production, agriculture, industry, mining aspects and contaminated site waste problems, which influence groundwater resources quantitatively and qualitatively in the long term.
Thus, a sustainable groundwater management demands structured recommendations for action. In the fields of groundwater exploration services and groundwater protection,

Geothermal potential denotes heat energy that is naturally occurring and which is stored in the subsurface. Geothermal studies are becoming more and more important as a result of a more critical resource and energy situation. In the context of renewable energy, the use of natural geothermal systems has an enormous potential for using geothermal energy in terms of electricity, heat energy, or for cooling processes. Independent of fossil and conventional combustible materials, geothermal studies makes a natural energy reservoir available that guarantees provision of energy over long periods of time.

Hydrometry is concerned with the quantitative determination potential for using geothermal energy in terms of electricity, heat energy, or for cooling processes. Data on surface water systems, groundwater and precipitation are collected spatio-temporally, evaluated and visualized. Collecting representative field data constitutes a key role in system analysis and presents the essential basis for corresponding solution concepts.

As a related section of hydrogeology, the subject hydrology includes the characterization, the conceptual linkage and the interactions between the various parts of the water circulation system. The quantification of corresponding process scales, the spatial variability as well as the effects of anthropogenic influences are indispensable for an overall system analysis.
Modern hydrology orients itself to the complexity of hydrological processes and therefore demands interdisciplinary approaches.
