Address: INRAE Centre Bretagne-Normandie, UMR SAS, 65 rue de St-Brieuc, CS 84215, 35042 Rennes Cedex, France

Fields of expertise: hydrology and solute transport, surface water quality

Keywords: agricultural catchments, headwaters, nutrient, carbon, suspended solids, water and solute transit times, biogeochemistry



Current research topic

My research topics are hydrology and biogeochemistry. I am interested in understanding the processes that determine the water quality of streams and rivers, especially in the context of agricultural environments. I use diverse monitoring and modelling approaches to characterize the transfer, transit times and reaction processes of water and some major chemical elements, mainly nutrients (N, P) and C.

I focus on small headwater catchments (10 ha - 100 km2) to medium-scale catchments (ca. 1000 km2).

I am involved in several observation platforms for research. In particular, I am scientific coordinator of a research observatory on agricultural catchments: the AgrHyS Observatory.

Current projects
  • Ecological Restoration of the Sélune River: Dynamics of water, sediments and dissolved chemical elements in the Sélune River before, during and after dam removal (2014-2021)
  • Modelling coupled dynamics of carbon, nitrogen and phosphorus stream concentrations in rural headwater catchments and analysis of climate effects (2017-2020). Supervision of the Ph.D. thesis conducted by Laurent Strohmenger.
  • Planning and management of water resources and agricultural development in the Loukkos river catchment: adaptation strategies to climate change (2020-2023). Co-supervision of the Ph.D. thesis conducted by Youness Hrour.
  • eLTER PLUS: Advanced community project for long-term ecosystem research in Europe (2020-2025)
  • ATCHA: Accompanying The adaptation of irrigated agriculture to climate CHAnge in South India (2017-2020)
  • CRITEX: National intonative equipment infrastructure for spatial and temporal monitoring of the Critical Zone (2011-2021).
