UAV based 3D modeling analysis in determining and preventing rockfall risks: A case study from Murtaza Village (Niğde, Turkey)

In this study, rockfall risks in Murtaza village, which is located within the central district of Niğde province and where active events are experienced, were evaluated using a high-resolution digital terrain model (DTM) created based on unmanned air vehicle (UAV) images, field measurement data, three dimensional (3D) models. During studies, 14 rock blocks that danger falling identified geometric measurements for each made. By measurements, modeled their properties RAMMS program total 1400 simulations, 100 from carried out DTM. Thus, kinetic energy, jump height, velocity, fall trajectories block determined. According to results, close settlements damped without being transported very long distances. These do not constitute significant since having values such as low speed, height. However, equant shape high volume, northwest slopes above settlements, risk. move distances depend geomorphological characteristics study area energy absorbed contact with houses, roads, etc., structures, or places slope decreases topography. To prevent area, retaining walls have 142 m 1.5 wide results these models, while 5 wall areas source blocks, 3 far stops progress blocks.
