dc.description.abstractRockfall is one of the most dangerous hazards in mountainous and hilly areas. In this study, rockfall characteristics of the KazıklıaliGorge (0.25 km2) in the lower Emli River Basin located in the SW part of the Aladağlar Mountains was investigated using unmannedair vehicle (UAV) technology and rockfall modeling. To determine rockfall properties, an orthophoto and digital surface modelwhich have a 3 cm resolution were created using UAV images. Then, whole fallen blocks more than 0.5 m in diameter were digitizedas polygons in GIS. As a result, 10,348 fallen rocks were determined in Kazıklıali Gorge. Via these polygons, density maps werecreated and frequency distributions were calculated. According to the spatial distribution of density, the geomorphologicalcharacteristics of the canyon affect the rockfall density. While the upper and middle parts of the canyon which are the narrowest havehigh density, the lower part of the valley which is the largest part has low density. The results of 3D rockfall analysis show that themaximum kinetic energy, maximum jump height and maximum velocity reaches 1400 kJ, 15 m and 32 m/s on the canyon walls,respectively. The upper and middle parts of the canyon walls which correspond to high rockfall density have maximum kineticenergy, rock jump height and rock velocity.en_US
