Monitoring the Potoška planina landslide (NW Slovenia) using UAV photogrammetry and tachymetric measurements

摘要: This paper summarizes the observation of Potoska planina landslide, which is located in Karavanke mountain range NW Slovenia. The landslide lies at tectonic contact between Upper Carboniferous and Permian clastic rocks, Triassic to Lower Jurassic carbonate rocks. Due active tectonics, rocks are heavily deformed and, consequently, highly prone fast deep weathering. also fissured due disturbances, result large quantities talus scree material covering part below crown. A greater spatial density springs wetlands, supplied from infiltration, evident prevailing geological, hydrological conditions, area different slope mass movements. presents monitoring surface movement patterns toe landslide. sliding composed tectonically weathered covered with a amount material, unstable landslides. Additionally, Bela torrent causes significant erosion increases possibility mobilization downstream. Based on said conditions field survey work, considered be most In order estimate over period 22.5 months five reconnaissance campaigns, periodic was conducted using unmanned aerial vehicle (UAV)-based photogrammetry, provides high-resolution images tachymetric geodetic measurements that enable accurate control photogrammetric analysis displacements. Using results monitoring, analyses UAV-based displacement patterns, elevations volume changes were all modelled for four periods. According our results, pattern indicates steadily downslope entire localized surges superficial slips.
