A Overview map of the Illgraben, showing the location of the three observation stations. The distance between the three stations, from Gazoduc downwards, is 1250 m and 450 m. Image: © swisstopo. B Bouldery front arrival at the most upstream station, referred to herein as Gazoduc. C Surge wave at CD 27. D Surge wave propagating through initially stationary material at CD 29. E, F Surge wave shown on image (D) at two different times in the LiDAR data, with the white dots showing the pre-event scan of the channel bottom, and the orange dots showing the instantaneous flow surface. The frames are 0.7 s apart.
