The Center for Applied Geoscience at the University of Tübingen is offering a PhD scholarship on the topic “Fully coupled hydrogeophysical inversion of 3D tracer tomography using temporal moments and Ensemble Kalman Filtering” starting preferably before July 1, 2017.
The project is funded by the Marie-Sklodowska-Curie Innovative Training Network “ENIGMA – EU Training Network for In situ imaGing of dynaMic processes in heterogeneous subsurfAce environments” within the Horizon 2020 Programme of the European Commission.
ENIGMA is a consortium of high profile universities, research institutions and companies located in France, Spain, Germany, Switzerland, Belgium, Denmark, Sweden, USA and UK, and will train 15 PhD students in total (Early Stage Researcher, ESR). This particular PhD (ESR PhD 13) will be based at the Center for Applied Geoscience at the University of Tübingen with research stays at ULG Liège.
Project description
3-D time-lapse ERT will be used for monitoring of salt tracer experiments and will be combined with GPR imaging of salt-tracer tests (with a secondment to the University of Liège), transient hydraulic tomography, heat tracer testing (also using natural sources as input signal). Other geophysical surveys may be used to obtain structural information of the subsurface. Fully coupled inversion methods of the hydraulic-geoelectrical system will be developed. The innovation of the ESR project lies in the development of fully coupled 3D-inversion methods for the joint analysis of field-scale tomographic data sets from multiple investigation techniques. In this context, Ensemble-Kalman methods will be adapted as inversion techniques. Field testing requires the extension of experimental concepts for tomographic salt-tracer testing with ERT and GPR monitoring and will be validated at the Lauswiesen test site of the University of Tübingen and then applied at other ENIGMA sites (Krauthausen, Hermalle, Selke).
