Applied hydrogeology and mountain catchment hydrology
The research activities focus on water cycle processes in catchments, in particular generation of surface and subsurface run-off, and on water management strategies for the sustainable utilisation of water resources. The basis for this is detailed knowledge of the spatial setting of the mountain and its hydrogeological characteristics, as it determines the sub-processes of water flow in catchment areas, karst and fracture systems.
Competences
Karst and fissure water – dynamics and protection
In Austria, a great deal of spring water from karst areas is used for drinking water supply. In order to optimise water management it is necessary to precisely quantify karst water recharge in its seasonal dynamics. Research work in this field results in interdisciplinary model studies providing the basis, among other things, for taking preventive action for karst water protection so as to avoid conflicts of use.
Another important area of work alongside karst waters deals with fissure waters that are found above all in the crystalline rock of the Central Alps and the Bohemian Massif; these waters are used primarily for local drinking water supply.

Catchment hydrology and sustainable water management
Surveying discharge components as a function of underground water storage and the relationship between surface water and groundwater is the basis for all water management activities in the catchment areas. In order to achieve sustainable management of resources, the Institute develops both regional water management concepts and scenarios for decision support systems (DSS), designed to provide a sound knowledge base for decision-makers in politics, administration and business.
