Summarizing: 1) 2006 vs. 2010 ALS comparison revealed that a small portion of the investigated landslide is more active than the remaining part. It seems that 42m3 were eroded and 38m3 deposited 2) interesting comparison between 2011 and 2013 TLS with the integration of SfM technique and survey. SfM is not so expensive, and it was possible to reach an accuracy of few cm respect to TLS. Interesting should be merging 1) and 2) project in order to have a wider time of observation 2006-to-2013 3) with automatic classification of LIDAR cloud points it was possible to distinguish, with a very detailed accuracy, different vegetation formation and types 4) 2 processes were observed for channel initiation: one related to erosion/landsliding, the other related to groundwater seeping upward (= springs). Classical methods for channel network extraction (At, ASt) are not useful since an unique treshold for channel network initiation, when processes are different, does not exist. This confirms previous work by Passalacqua et al. (2010) and Orlandini et al. (2011)
