Geological and Geophysical Tests to Model a Small Landslide in the Langhe Hills

摘要: In April 2009, North-West Italy was interested by heavy rainfalls that triggered several landslides, especially of shallow type, and caused relevant rise water level in many rivers, some cases even beyond the alert level. Particularly hills near Alba (NW Italy), landslides occurred, most them belonging to debris flow or soil slip types. this area, a small but interesting landslide involved local road high quality, recently planted, vineyard. The present study shows use different disciplinary approaches focused understand behaviour landslide: particular, besides geological geomorphologic studies, detailed topographic geophysical surveys together with an situ geotechnical/geomechanic characterization were applied. combined interpretation techniques field observations allowed define technical model landslide, both surface than depth, clarified triggering mechanism perform back analysis on strength pore pressure parameters.
