PhD 15 : Integration of dynamical hydrogeophysical data in a multiple-point geostatistical framework

This position has been filled!

The Applied Geophysics Research Unit at University of Liège is offering a PhD scholarship on the topic “Integration of dynamical hydrogeophysical data in a multiple-point geostatistical framework” 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 15) will be based at the Applied Geophysics Research Unit at University of Liège with research stays at CSIC Barcelona, AQUA Montpellier.

Project description

4D spatially distributed geophysical data sets, at an hourly or daily temporal resolution, gives new insights on transport processes and hydrogeological parameters distribution in the subsurface. The novelty of this project lies in their integration into inverse modelling techniques, historically developed to deal with sparse well dynamical data (breakthrough curves) or few temporal geophysical data. Furthermore, we will consider, prior to inversion, the validation/falsification of several plausible geological scenarios obtained from aquifer analogs using dynamic hydrogeophysical data. 4D ERT and SIP data contains information on transport processes and preferential flow paths that can help discriminate between various scenarios better than static images. A combination of 3D image analysis on geophysical data, temporal information and multidimensional scaling approach will be integrated in a multi-point geostatistical framework to compare outcomes from proposed scenarios with the observed data to update their conditional probability. The methodology will be developed in collaboration with early researchers (ESR, see description at https://enigma-itn.eu) from other institutions, in particular ESRs 13 and 14. New datasets from technologies developed by ESR6 (DTS) and ESR10 (GPR) will be integrated.
