High resolution LiDAR DEMs from regional or site specific surveys were used to map complex landslides such as deep-seated rockslides and earth slides-earth flows. Regional surveys DEMs were used to produce shaded relief maps that allowed delimiting rock slide units and sub-units at the slope scale. Multitemporal site-specific survey DEMs were used in eath slides-earth flows case studies to derive roughness maps that allowed defining the curvature fingerprint of the most active parts of earth flows, and to derive differential elevation maps that allowed assessing depletion and accumulation areas occurring in the slope as a consequence of post-failure dynamics.

Abstract

High resolution LiDAR DEMs from regional or site specific surveys were used to map complex landslides such as deep-seated rockslides and earth slides-earth flows. Regional surveys DEMs were used to produce shaded relief maps that allowed delimiting rock slide units and sub-units at the slope scale. Multitemporal site-specific survey DEMs were used in eath slides-earth flows case studies to derive roughness maps that allowed defining the curvature fingerprint of the most active parts of earth flows, and to derive differential elevation maps that allowed assessing depletion and accumulation areas occurring in the slope as a consequence of post-failure dynamics.
