Geomorphological Characterization, Monitoring and Modeling of the Monte Rotolon Complex Landslide (Recoaro Terme, Italy)

摘要: The Rotolon landslide, located in the upper Agno River valley (Vicenza, Italy), has threatened for centuries. During November 2010, after 637 mm of rainfall 12 days, a debris mass about 225,000 m3 collapsed from lowermost portion landslide and evolved into flow that channeled Creek riverbed, damaging villages Maltaure Parlati Recoaro Terme municipality. On December 8th, 2010 Department Earth Sciences University Firenze started real-time monitoring using GB-InSAR radar interferometer. data are elaborated to obtain weekly, monthly total cumulated 3D displacement maps time series ten control points selected on mass. Accurate field surveys were carried out analyze physiographic features validate ground deformation retrieved data. geomorphological features, supported by data, led an interpretation complex as Deep Seated Gravitational Slope Deformation, whose detrital cover is often affected detachments triggering flows. detachment area was modeled order to: (i) calculate main geotechnical properties material means back analysis; (ii) define residual risk; (iii) simulate new critical scenarios topographic slope surface.
