Abstract

Geohazards represent a significant barrier for further utilization of environment. This article presents the use of statistical methods and analysis tools implemented in Geographical Information Systems (GIS) environment for geohazards assessment of small urbanization units. As a case study the Levoča region was selected, covering an area of 83.75 km² in total. The area is mostly affected by landsliding and flooding. The distribution of these geohazards is evaluated. The case study provides the prognosis of hazard spatial distribution, however not the time recurrence of their activation. The results of evaluation are prognostic maps of landslide hazard and flood hazard.

Key words: geohazards, landslide hazard, flood hazard, prognostic maps, Geographical Information Systems, Levoča case study
