Etude de la relation pluie-débit sur bassin versant en climat méditerranéen par le traçage chimique et isotopique naturel de l'eau (Réal Collobrier, massif des Maures, Var)

Abstract: IntroductionLe bassin versant est devenu depuis une trentaine d'années un outil privilégié pour l'analyse hydrologique. Il représente, pour la plupart des milieux et des échelles d'étude l'unité fondamentale de référence dans Ig estion des ressources en eau [l, 2, 3, 4, 5]. Après une approche générale et descriptive du milieu, l'intérêt des hydrologues s'est porté sur la problématique des modalités de transfert de l'eau sur le bassin. Cependant, les conceptions du fonctionnement hydrologique du bassin restent … Show more

“…However, the vapour can often be considered at equilibrium with the rain, and the temporal variability of the 180 concentration in the incident rain should be kept in mind. On the R6al Collobrier catchment, this variability may reach more than 5 %0 [Marc, 1994]. As it is known on forested catchments, the canopy retains a certain amount of the rain, it is obvious this part of the incident isotopic signal cannot be found in throughfall or stemflow.…”

“…The annual rainfall averages 1000 min. Most of it is irregularly spread from fall to spring [Martin and Marc, 1993;Marc, 1994]. Many thunderstorms (I >70 mm/h) swoop down on the catchment in Oct. and Nov., while softer (I<10 ram/h) but more numerous rains water it during the winter and the spring.…”
