International audience; Karst systems, as well as springs, are vulnerable to water perturbation brought by infiltration. In this research, sources of water perturbations were examined. The first objective is to provide a method that can determine the

International audience; On the edge of sedimentary basins, burial of geological layers can involve the formation of confined karst aquifers. In some cases, relationships between confined and unconfined karst aquifers can exist and imply an increased

In parts of the Aquitaine sedimentary basin (France), groundwater resources management is hampered by the karstic nature of carbonate aquifers. This leads to temporal variability of flows and chemical signatures of springs and high groundwater vulner
