Laboratory of HYdrology and GEochemistry of Strasbourg (LHyGes - UMR 7517), has been founded in January 2009. It belongs to CNRS and Strasbourg University (UdS) and is one of the research unit of the Earth Science Department called "l’Ecole et Observatoire des Sciences de la Terre (EOST)".

LHyGeS results from the merging of three former research units : the "Centre d’Ecologie Végétale et d’Hydrologie CEVH / UMR-MA106, the teams "Géoparticules", "Géochimie isotopique" and "Interactions Fluides-Roches" of the Centre de Géochimie de la Surface CGS - UMR7517 and the team "Hydrologie et Transferts en Milieux Poreux" of l’Institut de Mécanique des Fluides et des Solides (IMFS - UMR7507).

The research activities of LHyGeS are focused on flow and transport in hydrosystems. These activities associate geochemistry with hydrology in order to improve our understanding of the processes at different scales (laboratory, field) and to build reliable models. LHyGeS has a great experience in developing experimental setups at field scale and laboratory scale to study flow and transport water catchments, soils and aquifers. The researchers are also involved in developping alternative new numerical and inverse methods for surface and subsurface flow and transport.
LHyGeS is in charge of the "Observatoire HydroGéochimique de l’Environnement" OHGE.

The research at LHyGeS is organized into three teams : Reactive Transferts in the Hydrosystems (TreHa), Methods and Numerical Tools for the Continental Hydrosystems (MoNHyC) and the Isotopic and Geochimistry and Chemistry of the Environment (GiCe).

On January 1st, 2016, there are 11 researchers (CNRS), 20 Adjoint/Professors (Université de Strasbourg, Engees-Ministère de l’Agriculture, CNAP), 18 enginners and technicians (CNRS, UdS, Engees), 18 PhD and post-docs. working at LHyGeS.

The LHyGeS’ full description is also available under the pdf format.
