The geological subsurface is characterized by human interventions and exploitation of the available geo-resources, especially production of ground water for drinking water supply purposes. Examples of other types of subsurface use are near surface as well as deep geothermal energy, energy storage by e.g. gas storage, the disposal of hazardous waste and the use as construction site for buildings and infrastructure. Soil and ground water contamination from small scale industrial leakage or from large scale agricultural land use cause water quality problems. The characterization and quantification of the interactions between the protected resource ground water and the individual interference in the subsurface pose new challenges for scientific research. The working group Geohydromodelling therefore contributes by a quantitative description and prognosis of the governing processes in the subsurface through numerical process simulation to the protection and sustainable use of the subsurface resources.

Research of the working group Geohydromodelling concentrates on the development and implementation of numerical methods for the simulation of coupled subsurface flow and reactive transport processes in porous and fractured media. Of special interest are the induced hydraulic, mechanic, thermal and geochemical processes and their interactions. The software developed is applied for numerical simulations of scenarios as well as laboratory and field scale cases in the fields of hydrogeology, aquatic geochemistry, geotechnics and reservoir simulation. The focus of recent years was the program development for the simulation software OpenGeoSys with contributions to software structure and reactive transport processes in one- and multi-phase systems, and applications in the areas of ground water contamination, parameter identification from laboratory experiments, CO2 storage, geo-thermal use of the subsurface and geological energy storage.


These topics and methods are part of the curricula of the Bachelor and Master courses of the Institute of Geosciences in both lectures and exercises and are applied in Bachelor and Mater thesis works. The aim is to establish numerical process simulation as method for environmental assessment and prognosis tool in related applications.
