TXT-tool 1.386-2.1 Landslide susceptibility assessment method

Abstract

A method was developed for the susceptibility estimation of different landslide types, and tested in the Bovec municipality, NW Alpine Slovenia. The purpose of the susceptibility maps, at the 1:25,000 scale, is to be used in spatial planning by the local municipality to minimize potential landslide hazard. The requirements taken into account were the following: expert approach, GIS tools support, reasonable production time, and the product being simple to read and understand. The elaboration of the final products comprises four phases, the first three of which are desktop phases: (1) synthesis of archive data, (2) probabilistic model of landslide susceptibility, (3) compilation of phases 1 and 2 into the final map at the 1:25,000 scale. The fourth phase consists of field reconnaissance of areas considered most hazardous.
