Development of fully coupled 3D inversion for in-situ monitoring of salt-tracer tests with ERT and cross-hole GPR
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 transient hydraulic tomography or heat tracer testing . Other geophysical surveys may be used to obtain structural information.
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 the Lauswiesen site of the University of Tübingen and then applied at other ENIGMA sites.
Tasks and methodology
- Hydrological salt tracer tests combined with geophysical surveys such as electrical resistivity tomography and GPR at the local test site of Lauswiesen
- Development of an effective scheme for a fully-coupled inversion of geophysical and hydrological data
- Adapting Ensemble Kalman methods for data inversion techniques
Data & Datasets
Future datasets produced during the research project will be inserted in CAMPOS database.
