Due to these deformations and rock structures, many rock falls occur in the region. In this study, the volumes of fallen rock blocks were calculated by using the latest technological measurement technique, unmanned aerial vehicle (UAV), terrestrial laser scanner (YLT) and classical methods (photo scaling and tape measurement). Detailed 3D model of study area was created. The volumes of selected four different rock blocks were calculated by three different methods and the results were compared in this study. In addition, advantages and disadvantages of all methods are discussed. The form, volume and shape of the rock blocks play an important role in the calculation of fallen rock's jump and advance distance over the area. It will also determine the magnitude of the damage that will occur. Therefore, precise modeling and volume information are of great importance in such studies.trinfo:eu-repo/semantics/openAccessİnsansız Hava Aracı(İHA)Yersel LazerModellemeKaya BloklarıUnmanned Aerial Vehicle (UAV)Terrestrial Laser Scanning (TLS)3D ModellingRockmassArticle20346547110.35414/akufemubid.679005
