V. Marc et al., STUDY OF STREAMFLOW PROCESSES WITHIN A ME DITERRANEAN CATCHMENT - AN APPROACH BY STABLE ENVIRONMENTAL ISOTOPES AND WATER CHEMISTRY, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 323(1), 1996, pp. 57-64
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.
