Abstract
Landslides in alpine environment are present as earthflows, rock falls, shallow debris flows, among others. The dynamics of the surface deformations are due either to the inner geomorphological processes, extreme weather events or human activities that aggravate and/or accelerate it.
In this work, we combine diverse technologies (sensors) at different spatial and temporal scales (platforms) to understand better the complexity of the gravitational mass movement in Corvara landslide located in the Italian Dolomites.
The setup consist of: (i) a monthly surveying GNSS for tracking artificial corner reflectors (reflecting objects) used in three different scales for determining velocity vectors: in-situ, proximal and remote sensing. (ii) two in-situ stations equipped with DSLR camera with an automatic time-lapse program based on a low-cost solution system acquiring two daily images covering active part of the landslide for tracking objects and doing photogrammetry analysis, (iii) an UAV platform with compact cameras flying on entire landslide (8 ha.) every semester for proximal sensing scale retrieving DEM, orthomosaics and cloud points determining 6-axis movement in objects and (iv) integration of Synthetic Aperture Interferometry (InSAR) analysis based on Sentinel-1 for remote sensing applications. The benefits and drawbacks of every approach will be presented.
