Rockfall Susceptibility Assessment at the Municipal Scale (Bovec Municipality, Slovenia)

A detailed rockfall susceptibility map of the Bovec municipality at 1:25,000 scale was produced by application of the methodology, developed at the Geological Survey of Slovenia. A Chi-square analysis with a linear weighted sum model approach was used on the basis of selected spatio-temporal factors (lithology, strata dipping, slope angle and distance to faults) for defining the rockfall areas and classifying them according to probability of rockfall occurrence. The final product is a rockfall susceptibility map (only for source areas in this phase), which serves as one of the bases in municipality spatial planning. It is also available through a web application for general public access. The purpose of the latter is in part also raising the public awareness.
