Abstract
Streamflow mechanisms using stable environmental isotopes and water ch emistry have been studied in the Maurets catchment (Real Collobrier, m assif des Maures) over 2 years. In mediterranean climate and metamorph ic context, we identify, during flood events, an important contributio n of shallow pre-event water. Hydrographic separations using the natur al water borne tracers reveal the evolution with time of the different flow component proportions, in relation with saturation progression. A dynamic model of flow processes is proposed where the moisture condi tions before the flood play a key role.
