According to estimates, 25% of the territory of the Republic of Serbia is affected by landslide processes. In the spring, when snowmelt is accompanied by the maximum amount of precipitation, a great number of landslides have been activated within the territory of Serbia. The year 2006 had a particularly large number of registered landslides accompanied by huge material damages. Because a landslide data base for the territory of Serbia does not exist, it is very difficult to carry out the regular assignment of land use and to make a spatial development strategy. This imposed a need for methodological development of landslide hazard zonation (LHZ) for the territory of Serbia. The Kolubara River Basin was selected as an area with a significant number of landslides occurence. The spatial distribution of landslides is a result of the interaction of many parameters. Landslide susceptibility zones in the Kolubara River basin were identified by heuristic analysis of landslide causal factors - local topography, morphological and geological setting, and the existing and past landslides identified the study area. Based on the results obtained in this study, it was found that 243.75 km² or 6.69% of the total area was prone to landsliding. The results can be implemented as a base for development of LHZ model for the overall territory of Serbia, and will represent the first step for compilation of a landslide data base.
