Manager of the Auverwatch site : Hélène Celle-Jeanton


The Auverwatch 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 aquifer and thermo-mineral circulations.
The project focuses especially on the alluvial aquifer of the Allier River, that plays both an important socio-economic role - drinking water supply and agricultural development – and an ecological role as a part of the Loire watershed.


 Scientific Goals

Two main axes are developed:

1) a long-term follow-up of the hydrodynamic and hydrochemical parameters with for objectives, the study of the evolution of the quality and quantity of water in relation with anthropic and climatic modifications and the production of tools for the water management by competent authorities;

2) the implementation of an experimental site on the Allier hydrosystem, dedicated to the implementation of collaborative and multidisciplinary projects, aiming at better constrain the alluvial aquifer and at improve the understanding of the relations between aquifer and river, with a focus on the reactivity of the alluvial deposits.
