The hydrogeology and environmental geology laboratory at University of Liège is offering a PhD scholarship on the topic “Joint heat and solute tracer test inversion for imaging preferential pathways” 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 11) will be based at the hydrogeology and environmental geology laboratory at University of Liège with research stays at BRGM Orléans, FZ Jülich.
Project description
The characterization of subsurface heat and solute transport is particularly challenging due to the existence of preferential transport paths at multiple scales. The ESR project aims at characterizing the role of preferential pathways (channeling) on transport based on dual-domain modelling approaches. The main innovation is to combine solute and heat tracer tests which have different sensitivities to preferential pathways and matrix diffusion processes. Field experiments will combine multiple wells injection and pumping experiments using solute and heat tracers complemented by DTS and geophysical imaging (GPR and ERT/SIP). Experimental campaigns on two different test sites (alluvial sediments in Hermalle hydrogeophysical site and fractured bedrock overlaid by weathered rocks in India (H+ Hyderabad site)) will be used to assess the added value of the proposed experiments to identify preferential flow paths and their influence on model predictions. Interactions with other early researchers (ESRs, see description at https://enigma-itn.eu) include fibre optic monitoring of temperature and flow (ESR6), model comparison for spreading and mixing (ESR9), GPR (ESR10) and SIP (ESR12).
