Monitoring dedicated to the set up of an alert system for landslide triggered debris flows: the Valloire case study (Savoie, France)

Résumé

The Rieu Benoît is a debris-flow-prone catchment located in Valloire (Savoie, France). In 2011, a lateral landslide was detected about 600 m upstream of the fan apex where houses are present. This landslide has evolved slowly but is likely, in case of rapid collapse, to provide up to 200,000 m3 of material to the channel and generate intense debris flows thus threatening human settlements on the fan and in the Valloire ski resort. We present the definition of a protection strategy based on the principle that a catastrophic evolution of the landslide can be detected sufficiently in advance to set up an effective alert procedure.
