Stratégie d’observation pour la quantification des flux de contaminants particulaires dans le Rhône : l’Observatoire des Sédiments du Rhône (OSR)

Abstract

International audienceA long-term goal of the Rhône Sediment Observatory is to quantify suspended particles and associated contaminant fluxes along the Rhône River from Lake Geneva to the Mediterranean Sea, from hydrological event to annual scales. Facing the complexity to evaluate these fluxes, an original observation strategy was developed to produce dense datasets regarding liquid discharges, suspended particulate matterloads (from turbidity), particle-size, organic and inorganic contaminant concentrations from centrifuge or sediment trap samples. Eventually, continuous time-series and flux calculation were established and made available in an efficient database (BDOH/FluxOSR)
