TL;DR: In this paper, the susceptibility conditions to gully erosion by means of GIS and multivariate statistical analysis was characterized by using field surveys and interpretation of aerial images of 260 gullies in a 9.5 km 2 river catchment in central-northern Sicily.

TL;DR: In this article, a 40m digital elevation model (DEM) was used to compute the values of nine topographic attributes (primary: slope, aspect, plan curvature, profile curvature; secondary: stream power index; topographic wetness index; LS-USLE factor); from available thematic maps and field checks three other physical attributes (lithology, soil texture, land use) were derived.

TL;DR: In this paper, a multivariate approach was applied to assess the landslide susceptibility on the basis of three selected conditioning factors (lithology, slope angle, and topographic wetness index), which were combined in a Unique Condition Unit (UCU) layer by intersecting the UCU layer with the vector layer of the diagnostic areas.

TL;DR: In this paper, a susceptibility map for an area, which is representative in terms of both geologic setting and slope instability phenomena of large sectors of the Sicilian Apennines, was produced using slope units and a multiparametric univariate model.
