Sažetak:
The aim of this paper is to present preliminary rockfall susceptibility assessment based on remote sensing and automated kinematic analysis for the steep slopes above the Town of Omiš. Collection of spatial data was performed by terrestrial laser scanning and unmanned aircraft vehicle to derivate high-resolution point cloud models. Split-FX and CloudCompare software were used to extract discontinuity surfaces and to determine their orientation. Automated spatial kinematic analysis was performed for each polygon of slope surface model in order to identify locations of possible instability mechanism. From the results of the spatial kinematic analysis and with the calculation of Kinematic Hazard Index, the most critical parts on the slopes for the occurrence of possible instability mechanisms were identified. Resulting rockfall susceptible areas, unstable blocks and probable instability mechanisms on the investigated slopes provide the input data that can be used to determine critical areas for further deterministic slope stability analysis, as well as for rockfall hazard and risk assessment.
