MAPA PODATNOŚCI OSUWISKOWEJ W SKALI REGIONALNEJ - PRZYKŁAD Z DOLINY SANU NA POGÓRZU DYNOWSKIM

Abstract

LANDSLIDE SUSCEPTIBILITY MAP IN A REGIONAL SCALE - EXAMPLE FROM OF SAN VALLEY IN THE DYNÓW FOOTHILLSAbstract. Dynów Foothills is an area Carpathians where mass movements, in particular landslides are phenomena commonly occurring. They affect the evolution of the slopes in both the long (thousands of years) as well as shorter (up to several years) intervals. Therefore, the effects of landslide movements should be an important consideration when planning. The objective was to develop a numerical GIS landslide susceptibility maps in scale 1:25 000 for the selected area of the San river valley in the Dynów foothill. These maps are important for spatial planning in communities and counties, and landslide risk assessment. GIS was used to model passive five factors: flysch lithology, tectonic, slope, exposure and altitude. Susceptibility was calculated of the Weights of Evidence method.
