We analysed factors influencing the mass fluxes – influence of soil types, slope, profile, planform and total curvature in the Kamniška Bistrica and Sora river basins, The aim of this dissertation was to show the differences in influencing factors between areas of mass flow initiation and stopping in the two basins. Polygon capture, processing, statistical analysis and graphs of slope movements were carried out in ArcGIS Pro and R software environment. Orthophotos, laser scanning images (from years 2014, 2015 and 2023) and a 1 : 25,000 pedological map were used. 855 landslides were analysed in the Kamniškak Bistrica basin and 539 in the Sora basin. Paired t-tests showed statistical differences between the mass flow triggering and stopping zones for slope and curvature in both basins. Slope was expectedly higher in the triggering areas than in the stopping areas. Calculated values of total curvature data showed that positively curved surfaces are more susceptible to mass flows, whereas landslides are arrested on negatively curved slopes. Slope movements are generally more frequent on non-carbonate soil types and less frequent on carbonate soil types, but in our case they also occurred on otherwise unusual soil types due to large amounts of rainfall.
