Volume, Peak discharges and Froude Number of Debris-Flow Surges: 10 Years of Monitoring on the Réal Torrent (France)

This work presents a summary of data on debris-flow monitoring stations focusing the surge scale rather than full-scale event (several fronts and surges with intermediate diluted flows). Surge-scale are not easily accessible for modellers but would be very beneficial community. A processing protocol is offered, its application to station R?al Torrent described (drainage area: 2 km , SE France). Investigated bulk features volume, front height, peak discharge, Froude number. investigation leads statistical distributions these parameters 34 gathered from 2011 2020. Their volumes typically few thousand cubic metres, their flow height 1 m, discharge dozens metres per second number near critical. Results drawn this will great asset better feed numerical experiments realistic, field-driven features.
