Post Doctoral position in imaging karstic aquifer during flood events with passive seismics methods via EURAXESS

University Bourgogne Franche-Comté

Besançon, France 🇫🇷

OFFER DESCRIPTION

Context

Karst aquifers are critical groundwater resources impacted by land-use and global climate change.
These reservoirs are known for being complex mediums, generally not accessible, presenting a highly heterogeneous distribution of permeability (conduits, fractures, faults, rock matrix). For this reason, their functioning is still poorly understood.

This research is part of the interdisciplinary project SISMEAUCLIM (2020-2022), which aims at better characterizing the response of a karst aquifer in the Jura mountains, at the scale of a catchment basin (Fourbanne, Doubs), during extreme meteorological events (flash floods, drought).

The project involves three teams from the University of Bourgogne-Franche-Comte, specialized in Seismology, Hydrogeology and Climatology located in the Chrono-environnement (Besançon) and Biogéosciences institutes (Dijon). 
A PhD thesis linked to the project has started in October 2020, which focuses in jointly analyzing seismological, hydrogeological and atmospheric data recorded on the aquifer.

Work description

Hydrogeological and passive seismic monitoring of the Fourbanne aquifer have been carried out for several years by the SNO Karst observatory JURASSIC KARST and the JURAQUAKE seismological network (OSU THETA).

This dataset will be completed by a 4-monthacquisition campaign at the end of 2021, which will consist in the deployment and maintenance of 65 seismological sensors (SISMOB-RESIF) and 30 rain-gauge stations over the whole catchment basin.
A reconnaissance campaign is in progress and the rain-gauge stations will be installed by the end of summer 2021.

The post-doctoral position is dedicated to the data processing recorded by this dense seismological network. The main task is to apply seismic interferometry methods for monitoring velocity changes induced by water flow across the catchment basin.

The post-doc will take part to the field work together with researchers, students and technicians involved in the SISMEAUCLIM project and participate to the maintenance of the temporary seismological network.

Additional comments

This post-doctoral position is funded by the Région Bourgogne Franche-Comté, in the frame of the SISMEAUCLIM project.

The successful applicant will be based at Chrono-environnement (UMR 6249 CNRS, Besançon, France).

The position will start by the end of 2021 or in 2022 for 12-month duration.
