Multiscale Geophysics of soil-plant systems
Group Leader: Prof. Dr. Anja Klotzsche
We develop and apply hydrogeophysical methods to enhance the characterization of the critical zone including aquifers, peatlands, permafrost soils and agricultural fields. One of our main foci is to enhance the resolution of small-scale heterogeneity related to the soil-plant system. This professorship is a joint appointment of the Forschungszentrum Jülich and the University of Cologne.
Key Research Areas and Methods:
- Hydrogeophysics, Hydrology and Permafrost Geophysics
- GPR, GPR Full-waveform Inversion
- Electromagnetic Wave Propagation
- Geophysical Modeling, Imaging and Inversion techniques
- Wetlands/Peatlands Geophysics, Environmental and Engineering Geophysics
News and Links:
- Mastertopic projects: High-frequency GPR full-waveform inversion to characterize soil structures inside a lysimeter
GPR Roundtable meeting:
Georadar Rundtisch Gespräch (GPR Roundtable meeting)The GPR roundtable meeting is aimed at scientists, engineers and georadar/GPR users with the aim of constructively discussing and analyzing new knowledge and insights. The goal of the workshop is to spread knowledge about GPR technology and its use, as well as, to provide a unique possibility to participants to exchange ideas about the advances in their work and discuss their results. Results are presented in German and English
