Tracing streamflow generation during rain-on-snow events using stable water isotopes

Séminaire de : Andrea Rücker, Doctorante au WSL et l’ETH (Institut fédéral de Recherche sur la forêt, la neige et les paysages et Ecole Polytechnique Fédérale, Zurich, Suisse)

Abstract :
To better understand how rain-on-snow (ROS) events affect snowpack outflow volumes and streamflow generation, we measured snowpack outflow volumes and isotopic composition during several ROS events with automated snowmelt lysimeters at three locations in a pre-Alpine catchment.
We quantified the spatiotemporal variability of snowpack outflow and its relative contribution to streamflow, and identified rainfall characteristics and initial snow depth as major controls on snow hydrological processes.
