PhD Position “Current deformation and groundwater reservoirs in the Jura mountains”

Job description

PhD thesis proposal (financed, start in September/October 2025):

“New insights into current deformation in the Jura and implications for groundwater reservoirs: seismological and geodetic measurements and use of accumulated databases”

Supervisors: Andrea Walpersdorf, Institute for Earth Sciences (ISTerre), Grenoble, and Julie Albaric, Chrono Environment, Besançon, France

The aim of this thesis project is to study active deformation in the Jura Arc (France-Switzerland border region), using recent geophysical data (GNSS and seismological data). One of the objectives is to distinguish between deformation of the sedimentary cover and that of the basement (‘thin skin’ or ‘thick skin’ deformation). The new data of the project will make it possible to estimate the slip rates of active faults, in particular the Vuache fault, in order to assess their contribution to the seismic hazard, particularly in sensitive areas such as the Bugey nuclear power plant. An exploratory part of the thesis examines the links between crustal deformation and groundwater reservoirs in the Jura massif, with a focus on the Fourbanne karstic aquifer, a multi-instrument site at the interface between several thematic Earth Science observatories. The aim is to study the link between hydrogeological variations, surface deformation and seismicity, thereby contributing to a better characterisation of water resources and seismic hazard in the region.

Candidates should ideally have an education in Earth Sciences or physics, and the capacity to interact efficiently with specialists of the different disciplines involved in this project. Autonomy and proactivity will be appreciated.
