Water, Resources and Fluid Interactions Department

The "Water, Resources and Fluid Interactions" department includes five research teams and a joint laboratory working on complementary issues and approaches related to the water and element cycle in natural environments.

The teams of the department study water resources, both from a qualitative and quantitative point of view (Water and Territories), the development of reservoirs and energy and/or mining resources, the action of water and hazards on the evolution of landforms and sediment transport (Rivers), the interactions between fluid dynamics, transport processes and reactive phenomena in porous underground media (TERA), fluid-rock-deformation interactions in orogenic systems (Frodo team) and finally the modeling of physical processes and couplings at the interfaces between tectonics, geomorphology and hydro(geo)logy (DEMODE). In addition to these five teams, there is Fractory, a joint laboratory (LabCom) between the CNRS, the University of Rennes 1 and the company Itasca Consultants on the modeling of environmental impacts and risks, particularly those related to the flow and transport of fluids, and the improvement of methods of exploitation of geological resources.

This department consists in 5 teams and a LabCom (Joint Laboratory)

Water and Territories

Coordinator Luc Aquilina

eaux et territoires

The Water and Territories team addresses the issue of water resources from the perspective of resource functioning, the impact of climate change and human activities, as well as the management of this resource.

River : Sediment Transfer and Extreme Events

 Coordinator Alain Crave

The Rivers team addresses questions related to (1) the geomorphology of rivers and sedimentary bodies, (2) the upstream/downstream evolution of transported sediments on a "Source to Sink" continuum, (3) the coupling between reservoir geometry, water flows and sediment transport.

TERA : Fluids, Transport et Reactions

 Responsable Yves Méheust

L'équipe TERA  étudie la dynamique des fluides et des phénomènes de transport, et leur couplage aux processus  réactifs géochimiques et microbiologiques. L’objectif est d’étudier les processus couplés d’écoulements complexes, de transport réactifs, et de processus microbiologiques se produisant à la micro-échellle, et de caractériser leur impact sur les dynamiques des systèmes environnementaux aux grandes  échelles d’espace et de temps

FRODO : Interactions between Fluids Rocks and Deformation

 Coordinator Philippe Boulvais

Analyse du contrôle tectonique de la mise en place de veines de magnésite dans les ophiolites de Serbie et ses conséquences sur le processus de carbonatation du manteau.

The FRODO team aims at studying and characterizing the interactions between geological fluids, rocks (basement, basin, magmatic) and their deformation, through the coupled use of field geology and numerical modeling of processes.

DEMODE: Modeling Challenges

 Coordinators Philippe Steer and Benjamin Guillaume

The "Modeling Challenges" team [Demo(de)] offers a space of scientific animation around the modeling of the physics of geological processes and the couplings in particular at the interfaces between tectonics, geomorphology and hydro(geo)logy.

FRACTORY

 Coordinator Philippe Davy

Fractory is a joint laboratory (LabCom) created on January 1, 2018 between CNRS, the University of Rennes 1 and the company Itasca Consultants (ICSAS). Its field of activity is the modeling of environmental impacts and risks, and the improvement of geological resources exploitation methods.
