摘要：A controlled rain experiment has been performed on the Super-Sauze mudslide (South French Alps) in order to better understand the hydrology and mechanics of such type of landslides. The rainfall experiment was conducted during several consecutive days on a plot of about 120 m 2 . The landslide displacements were monitored by Terrestrial Laser Scanning (TLS) during 5 days from July 10- 14, 2007 with one scan acquisition per day. The scans were fitted on a stable slope outside the rain area. Three techniques were used to characterize the displacements: the benchmark method, the cloud to cloud comparison method and the shaded relief image correlation method. All techniques indicate an average displacement rate of 3.2 cm.day -1 with a slight acceleration on day 3. The benchmark method allowed to identify the direction of sliding and thus to estimate the dip of the slip surface. Information on the velocity vertical profile can also be derived from the benchmark method
