Multi-date SfM (Structure from Motion) photogrammetry of the St Antoine torrent (Bourg d'Oisans, France). Sediment budget analysis of the 1998 rockslide and ...

SfM photogrammetry was applied on airphotos from 1971, 2011, and our 2016 gyrocopter flight. Sediment budgets could be made for the 328 000 m3 rockslide that occurred in 1998 with uncertainties using the M3C2 analysis. The 2016 survey highlighted the active rockfall areas that still exist and varify that the large storage still remains in the torrent over the town below.
