Abstract(s) :

(Anglais) Geophysical methods allow imaging the structure of the epikarst. However, studying groundwater transfer in a non-saturated zone is still a challenging task. Tracing is then used to remedy this problem and to relate water flow with geological structures. These studies are all the more important than the epikarst is a vulnerable area with important water reserve. In order to validate the hypotheses issued on the basis of the geophysical methods, a multi tracer experiment was realized on the St Ferron site (Larzac, France). The study showed the importance of using tracing in addition to geophysical methods to validate the hypotheses on the flows and thus better know the epikarst and its functioning.
