| Zusammenfassung |
| On the 27 and 28 April 2009, the area of Oltrepo Pavese in
northern Italy was affected by a very intense rainfall event that caused a
great number of shallow landslides. These instabilities occurred on slopes
covered by vineyards or recently formed woodlands and caused damage to many
roads and one human loss. Based on aerial photographs taken immediately
after the event and field surveys, more than 1600 landslides were detected.
After acquiring topographical data, geotechnical properties of the soils
and land use, susceptibility analysis on a territorial scale was carried
out. In particular, different physically based models were applied to two
contiguous sites with the same geological context but different typologies
and sizes of shallow landslides. This paper presents the comparison between
the ex-post results obtained from the different approaches. On the basis of
the observed landslide localizations, the accuracy of the different models
was evaluated, and the significant results are highlighted. |
