The H+ observation service was created in 2002 with following missions:
The first goal of the H+ observation service is to maintain and coordinate a network of experimental sites capable of providing data – including chronicles or data on long term experiments – for the characterisation, quantification and modelling of water, element and energy transfers in underground aquifers.
The coupling between measurements, theories, and models is a fundamental goal of the H+ observation service. The observatory aims to create a long-term relation between research teams interested in the theoretical, numerical or experimental aspects of transfers in heterogeneous media.
The H+ observation service also has the task of establishing a partnership between fundamental research, training and operational partners. Training activities are organised on the exploitation of the resource and the prevention of environmental risks.
The H+ database includes the data acquired on the sites of H+ National observation service:

Description Manager of the Auverwatch site: Hélène Celle-Jeanton The AUVERWATCH (AUVERgne WATer CHemistry) project aims at the quantitative and qualitative follow-up of characteristic water masses in Auvergne in order to observe the long-term evolution of these hydrosystems depending on anthropogenic modifications and climatic change. Four hydrogeological analogues have been selected, including rainfall, alluvial hydrosystem, volcanic […]
LARZAC
Description Manager of the Larzac site: Cédric Champollion The Durzon site is located on a karstic aquifer with an area of 100 km2 which supplies the Durzon Spring (average discharge 1.4 m3/s). This spring provides a natural supply of drinking water to the Aveyron portion of Larzac. The site is equipped to monitor the discharge […]
LSBB
Description Manager of the LSBB site: Naomi Mazzilli Scientific Goals In the heart of the karstic massif of Fontaine-de-Vaucluse, LSBB enables research to be undertaken at scales that are usually unobtainable, ranging from flowing fractures (61 currently) to a continuum of 14,000 m2 (beneath 30 to 519 m of cover rocks), with everything in between, […]
POITIERS
Description Manager of the Poitiers site: Gilles Porel The Poitiers Experimental Hydrogeological Site (SEH) was developed by the Hydrasa team (FRE 3114) as part of the Network of National Hydrogeological Sites (SNO H+), under the Poitou-Charentes Region’s “WATER” program (CPER 2002-2006). Located 2 km east of the Science Campus of the University of Poitiers, the […]
PlOEMEUR-GUIDEL
Description Scientific manager of the Ploemeur-Guidel site: Eliot Chatton Technical manager of the Ploemeur-Guidel site: Nicolas Lavenant The Ploemeur site (Morbihan) is located on an aquifer in fractured crystalline bedrock; since 1991 it has supplied one million m3 of drinking water annually to a town of 20,000 inhabitants. The chemical quality of the water extracted […]
H+ annual days 2024 (save the date)
The annual days of the H+ network will be held from 23 to 25 October 2024 in Poitiers. This meeting will provide an opportunity to present the state of progress of the H+ observatories. The program of H+ days is available here.
6th edition of the Colloquium of the Zones Ateliers Network (RZA)
The 6th colloquium of the Zones Ateliers Network (RZA) “Co-constructing research on socio-ecosystems” will take place from 17 to 19 September 2024 in Sainte-Menehould (Marne), in the territory of the Zone Atelier Argonne, which is one of the 16 Zones Ateliers of RZA. The call for abstracts closed on 21 June 2024.Registration is now open. […]
Continental Surface Modeling Days 2024
The 5th Continental Surface Modeling Days (JMSC) will be held in Strasbourg on 19 and 20 June 2024. The Continental Surface Modeling Days were set up to bring together and animate the relevant French-speaking community, through 2-day meetings every 2 years, with no registration fee, and by rotating regionally among the French sites involved in […]
