Technological advances in isotope measurement over the last few years [5][6][7] have paved the way for numerous applications of these tools in the water cycle [7][8] . New isotopic tools are increasingly being developed (Li, Cd, Zn... [7] ), as are new applications of "classic" tools, in particular the multi-isotopic approach. This multi-tool approach makes it possible to reduce assumptions about system functioning, and thus to better...
