Research Vision

The Hydro-Geophysics Group (HGG) does research on the highest level with the overall aim to develop methods for knowledge-based mapping and modelling of water resources for the benefit of society.

HGG combines geophysical instrument development with advanced data processing and inversion algorithms and hydrological modelling. The key geophysical methods are airborne and ground-based transient electromagnetic (TEM), induced polarization and DC and nuclear magnetic resonance sounding. TEM systems like SkyTEM, tTEM and  WalkTEM and the Apsu NMR system are examples of system originating from the research carried out by the group. Also, software’s like Aarhus Workbench and AarhusInv are products of years of development.

The group works with projects in Denmark and worldwide which is expressed in a large number of publications on the applicability of the geophysical methods for groundwater resource mapping, geotechnical applications and geological mapping. The group is highly international with students and scientists from all over the world. In addition, the group often have one or more guest professors and guest students from various countries.

The group has fostered several spin-off companies from Aarhus University. The largest one is SkyTEM Surveys Aps which today is one of the major players within airborne electromagnetic. The latest company is Aarhus Geosoftware Aps who commercializes and further develop some of the software originating from HGG.
