| Zusammenfassung |
| This paper deals with the use of time-series of High-Resolution Digital
Elevation Models (HR DEMs) obtained from photogrammetry and airborne LiDAR
coupled with aerial photos, to analyse the magnitude of recently reactivated
large scale earth slides – earth flows located in the northern Apennines of
Italy. The landslides underwent complete reactivation between 2001 and
2006, causing civil protection emergencies. With the final aim to support
hazard assessment and the planning of mitigation measures, high-resolution
DEMs are used to identify, quantify and visualize depletion and accumulation
in the slope resulting from the reactivation of the mass movements. This
information allows to quantify mass wasting, i.e. the amount of landslide
material that is wasted during reactivation events due to stream erosion
along the slope and at its bottom, resulting in sediment discharge into the
local fluvial system, and to assess the total volumetric magnitude of the
events. By quantifying and visualising elevation changes at the slope scale,
results are also a valuable support for the comprehension of
geomorphological processes acting behind the evolution of the analysed
landslides. |
