In the experimental catchment area of the Fontaine de Vaucluse, a long term monitoring has been completed. It enables the study of the system functioning with variable hydrological conditions. Coupling flow rates and Mg2+ concentrations permits highlighting the particular contribution of water with great Mg2+ concentration during low water...

The study of karstic systems is mainly based on hydrodynamic and hydrochemical data collected at system inlets (rainfall) and outlets (springs). Indeed, some complementary data base coming from speleological and hydrogeological explorations of natural cavities exist. However, they are not completely representative of all the types of flows....

For about 10 years, environmental tracing development using dissolved organic matter (DOM) has been the subject of several studies. Particularly, the use of characterization techniques, like fluorescence emission-excitation matrices has enabled the identification of DOM sources and monitoring them within mainland or marine hydrosystems....

This review aims to give an overview of the potential hydrogeochemical information can have for landslide research and analyses the use of hydrogeochemical information to unravel the hydrological processes in landslide triggering. Landslides are well known for their data shortage; especially in case the hydrogeology is heterogeneous and...

Les systèmes karstiques renferment d'importantes ressources en eau. Du fait de leurs complexités, ils sont généralement sous exploités. Le fonctionnement hydrodynamique et hydrochimique de leur zone non saturée est particulièrement mal connu même si un rôle important lui est accordé. Il apparaît donc nécessaire de progresser dans la...

For about ten years, environmental tracing development using Dissolved Organic Matter (DOM) has been the subject of several studies. Particularly, the use of characterization techniques, like fluorescence Emission-Excitation Matrices (EEM), has enabled identification and monitoring of DOM sources within mainland or marine hydrosystems....

Karst systems contain important groundwater resources. Due to their complexity, they are generally under exploited. Particularly, the hydrodynamic functioning of the unsaturated zone is badly understood even if its important role is admitted Today, the hydrogeologists are agreeing with the important function(s) of the unsaturated zone in karst...

The karstic system of th e 'Fontaine de Vaucluse' has been investigated for many years to get a better understanding of its global functioning. Yet, until now, the Unsaturated Zone (UZ) of this aquifer has been studied indirectly. With the access to the UZ provided by the galleries of the Low-Noise Underground Laboratory of Rustrel in France...

Since the decommission of the underground launching control room of the ground-based component of the French nuclear missile system, the whole installation has been turned into a cross-disciplinary underground laboratory. The LSBB is a unique low-noise underground laboratory because of its initial military conception and its location in the...

Assessing the recharge of underground hydrosystems remains an obstacle to understand their hydrologeological functioning. During a rain event, which part of the rain is evapotranspired ? And how much is temporarily stored within the soil ? These questions are particularly relevant in heterogeneous media such as karst hydrosystems. Currently,...
