Presentation

Zahra Thomas is professor at Institut Agro Rennes Angers, UMR SAS. She is working on catchment hydrology and groundwater modelling. Her mains skills are in numerical models, informatic, hydraulics and hydrology. She is involved in modelling and dating groundwater transit time and groundwater-river exchanges. She is also deeply involved in the deployment of field instruments for the monitoring of water fluxes and solute concentrations, in connection with land use and catchment/aquifer characteristics. She is teaching hydraulics, soil physics and numerical modelling.
