The combination of geological, topographical and climatic conditions causes mass movements. Rockfall, which is a frequently seen disaster at mountainous regions, gives damage to residential areas and transportation corridors. Rockfall barriers are being designed to capture falling rocks worldwide. The classical method applied in rockfall analysis is 3D modelling of the study area to determine rockfall trajectory with the help of Digital surface model (DSM). 3D rockfall simulation is performed in order to determine bounce height, maximum run-out distance and kinetic energy of rocks. DSM of the study area needs to be accurately determined to properly design barrier system. Unmanned aerial vehicle (UAV) can be used to prepare actual DSM from inaccessible areas. In this study, we prepared the DSM of the area which was affected from rockfall due to high rainfall with using a UAV.
