Réal Collobrier

The Réal Collobrier, the oldest French observatory on Mediterranean hydrology. The observatory of the Réal Collobrier basins was set up in 1967 to improve the knowledge of particular hydrological phenomena in the Mediterranean area. Located in forest and rural areas on metamorphic soils of the Massif des Maures in the Var, it is a landmark […]


OSR Toulouse

The Regional Spatial Observatory (OSR), labeled in 2007 by the National Institute of Sciences of the univers (INSU), is supported by the Center of Spatial Studies of the BIOSPHERE (CESBIO, OMP) The mission of the OSR aims at documenting on the long term the effects of the climate change and the increasing anthropogenic pressures on […]


The Earth surface evolves under the action of geological, chemical, physical, biological and anthropogenic processes involving a wide range of time and length scales (from the meter and the second up to the thousand of kilometers and the million years). These processes control the evolution of soils, the shape of landscapes and the coupling between […]

Jurassic Karst

Objective The Jurassic Karst (JK) scheme in place since 2009 aims to characterise the long-term evolution of the limestone aquifer system of the Jura mountains. Issues The karst’s low filtering capacity makes the water resources of the associated aquifer systems very vulnerable. The JK scheme is designed to study relations between the biogeochemical functioning of […]


FORKARST is an hydrogeological observatory coordinated by Avignon University (UMR 1114 EMMAH) as part of the Network of National Karst Sites (SNO KARST). It gathers two experimental sites at interlinked scales :  the fontaine de Vaucluse karst hydrosystem (basin scale) and the LSBB (Low-noise underground laboratory – local scale to mesoscale). Fontaine de Vaucluse is the […]


CRYOBS-CLIM ((The CRYosphère, a CLIMATE Observatory), is labeled in 2015 and is structured around the monitoring of the major components of the cryosphere: mountain glaciers / polar ice caps, snow cover and mountain permafrost. CRYOBS-CLIM is a SOERE grouping together 8 French laboratories and foreign partners, representing 53 actors in total. This new SOERE brings […]


AMMA-CATCH is a hydrological and meteorological observatory on West Africa. This national observation service (SNO) is dedicated to long-term monitoring of climatological, hydrological and ecological changes in West Africa. For this purpose, it gathers data from three mesoscale sites, which cover areas ranging between 10000 and 25000 km². The three sites are located at different […]



AgrHyS (response times in AgroHydroSystems), certified as Environment Research Observatory in 2002, is managed by INRA Rennes in collaboration with CNRS and Rennes Universities. It comprises two sites: Kervidy-Naizin in Morbihan, monitored by Cemagref since the establishment of Naizin BVRE (Bassin versant représentatif et expérimental) in 1970, in the Coët Dan watershed defined by the […]
