SNO H+

Network of hydrogeological research sites

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:

  • Ploemeur (Ploemeur & Guidel)
  • Poitiers
  • Larzac
  • LSBB
  • AUVERWATCH (Val d’Allier & Port-Douvot)
  • Rouen

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 […]
