Landslide Hazard Assessment Map as an Element Supporting Spatial Planning: the Flysch Carpathians Region Study

Landslides and rock falls are among the many phenomena that have an impact on sustainable construction infrastructure safety. The main causes of landslides natural meteorological hydrological phenomena. In building design construction, environmental monitoring by identifying geotechnical hazards must be taken into account, as appropriate hazard assessment contributes to ensuring future Carpathian region in southern Poland is particularly predisposed landslide formation. This may favored nature shapes associated with high steep slopes region’s valleys. Another reason for concern flysch geological structure, which characterized alternating layers water-permeable sandstones poorly permeable shales, clays, marls. Furthermore, presence a quaternary weathering cover makes structure more susceptible processes tectonic formations. paper presents results study whose aim was elaborate detailed map selected area Polish Carpathians, using statistical methods. approach based Hellwig method, seems useful susceptibility local scale relatively small area. A two-stage conducted. first stage research involved creation database parameters triggering factors, whereas second consisted adoption weights seven thematic sections their special features basis expert knowledge. developed result compared mapping made weight-of-evidence method. proposed data normalization method allows use analysis both qualitative quantitative collected from various sources. advantage this simple calculation procedure. large-scale (1:2000) might used assess specific cadastral units. Such becomes municipal spatial planning able influence investment decisions. Detailed maps crucial precise risk evaluation This, turn, one reduce serious economic social losses, landslides.
