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....

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....
