摘要：

By using C-13 as a tracer in karstic aquifers, one can distinguish between water from the unsaturated and the saturated zones, because the system behaves as one open to the biogenic CO2 in the unsaturated zone. This method shows that a significant reserve remains in the unsaturated zone at the end of the minimal flow. It is therefore likely that the unsaturated zone contributes to the outflow during this period. (C) Academie des sciences/Elsevier, Paris.
