Rhône Sediment Observatory

Rhône Sediment Observatory (OSR) is an interdisciplinary research programme on the hydro-sedimentary processes in the Rhône River, from Lake Geneva to the Mediterranean Sea. OSR produces knowledge on the flows and stocks of sediments (pebbles, gravel, sand, silt, etc.) and on sediments contaminants.

This knowledge allows to address the management issues related to sedimentary processes in the Rhône River: flood risk, protection and restoration of biodiversity, flows and stocks of contaminants in sediments, and sediment supply to the sea and coastline.

The mission of the observatory is to support sediments management along the entire length of the Rhône River. It brings together the points of view of research teams and operational staff (public establishments, decentralized State services, local authorities, private companies, etc.) through exchange and co-construction between science and management.
