About the research centre or Inria department

The Inria Rennes - Bretagne Atlantique Centre is one of Inria's eight centres and has more than thirty research teams. The Inria Center is a major and recognized player in the field of digital sciences. It is at the heart of a rich R&D and innovation ecosystem: highly innovative PMEs, large industrial groups, competitiveness clusters, research and higher education players, laboratories of excellence, technological research institute, etc.

Context

The Aqui-Aqua project (SAD Région Bretagne) is part of a partnership between Inria and the lab Géosciences Rennes.

The goal of the project is to generalize shallow aquifer models designed for some identified and well-monitored sites, to a whole region. It will be done under the assumption that their hydraulic and geochemical properties are correlated to their fundamental geologic characteristics, and especially their lithology.

If necessary, the contract beginning can be postponed until the end of 2024.

Assignment

There are three parts in the project :

  1. Use of transfer models, to extract observable phenomena from representative hydraulic and chemical properties of the catchments, as flow or nitrogen concentration chronicles. Field expeditions on interest sites will be programmed, for the recruited person to get familiar with the local geologic and hydrogeologic specificities.
  2. Identification of correlations between hydraulic and chemical properties and major geologic characteristics (eg. lithologie, weathering depth)
  3. Chart of hydraulic properties at the regional scale, and generalization of transfer models to non-monitored sites.

For more information, feel free to contact the supervising team before your application.

Collaboration :
The postdoc is co-supervised by Jean-Raynald de Dreuzy (Hydrology/Hydrogeology. CNRS, Géosciences Rennes) and Hélène Hivert (Mathématics. Inria and Géosciences Rennes).
The recruited person will also interact with

Camille Bouchez, (CNAP, Géosciences Rennes), Philippe Boulvais (Géosciences Rennes), Jean de Bremond d’Ars (Géosciences Rennes), Nicolas Cornette (Cydre project, BRGM and Géosciences Rennes), Camille Vautier (ENS Rennes, Géosciences Rennes) and Philippe Yamato (Géosciences Rennes).

 

Main activities

Main activities :

  • Determination of equivalent hydrolic and chemical properties on each monitored catchment, using numerical simulations.
  • Solution of contrained optimisation problems, to identify correlations between hydro-chemical properties and geologic characteristics of the catchments.
