CRITEX facilitates the description of hydrological, hydrogeological and geochemical functioning of selected watersheds in terms of the various contexts (rocks, soil, vegetation, climate, human activities, etc.) in order to better understand the effects of climate change on the future of the planet. The project comprises 21 laboratories belonging to four national research agencies and more than twenty universities.

CRITEX: The national innovative technology park for the spatial and temporal study of critical watershed areas –will allow the implementation of measurements in increments of time adapted to the dynamics of the processes studied and over long periods of up to several years. The quality of surface water and groundwater can thus be studied in detail in relation to the characteristics of the natural environment and those of the surrounding human activities. This project will also contribute to original metrological developments.

CRITEX will allow us to better understand how human activities and climate change affect the characteristics of surface water and groundwater. This understanding will contribute to better management of water resources in a variety of contexts. The acquired data will be made available to the public.

CRITEX will contribute to the functioning of the national infrastructure for combined research of watersheds, some of which have been monitored for several decades. It will strengthen the interaction between the scientific community working in the field and European and international networks combining measurement devices similar to those monitored nationally. Finally, it will allow France to become one of the leaders in the field.

The purpose of CRITEX (spatial and temporal study of Critical Watershed Areas) is to contribute to the transfer of technology in the field of environmental instrumentation.

The CRITEX project comprises 21 laboratories belonging to more than 20 universities and four research organizations: CNRS/GET, LHyGeS, Ecolab, Bioemco, IMPMC, IPGP, SAS, Irstea/HBAN, LISAH, LTHE, HSM, Irstea/ETNA, EMMAH, Chrono-environnement, Géosciences Rennes, IPGS, LCA, LDO, Géosciences Montpellier, Sisyphus and BRGM.
