The National Centre for Scientific Research is the largest public transdisciplinary research organization in France. It manages 1029 joint research units with universities and industries. The main coordination team, Geosciences Rennes laboratory, is a JRU (CNRS + Rennes University) that covers a large range of disciplines in earth sciences. It has received an A+ research rating from the 2010 AERES international committee evaluation. The Rennes hydrogeology group, which is composed of about fifteen permanent staff, has an international expertise on i) modelling of multi-scale properties of fracture networks, ii) modelling of flow and transport processes in heterogeneous media and on iii) field investigations of flow structures and chemical processes.
- The CNRS is coordinator of the H+ network of hydrogeological sites (www.hplus.ore.fr), which regroups 6 highly instrumented field observatories for long term monitoring and experimentation. The Rennes team supervises the Ploemeur fractured rock observatory (http://hplus.ore.fr/en/ploemeur), which hosts each year numerous scientific campaigns for testing new instruments and methodologies. The hydrogeology group has equipment and facilities for achieving flow and transport experiments both in the lab and in the field.
- UMR 7619 “Milieux environnementaux, transferts et interactions dans
les hydrosystèmes et les sols” (METIS, CNRS – UPMC) is a multidisciplinary research unit specialized in water, element, and contaminant circulation. It is the largest group in France developing the use of geophysical methods to study and quantify hydrogeology processes in the near surface. The area of expertise of the research group involved in the project, Physical Hydro[geo]logy, include the use of electrical and electromagnetic methods at every scale (from laboratory samples to airborn survey) and every frequency (from DC resistivity to very high frequency ground penetrating radar).
