dc.description.abstractIn this study, rockfall hazards in Murtaza village, which is located within the central district of Niğde province and where active rockfall events are experienced, were evaluated using a high-resolution digital surface model (DSM) created based on unmanned air vehicle (UAV) images, field measurement data, and three dimensional (3D) rockfall models. During the field studies, 14 rock blocks with falling potential were identified and geometric measurements for each of the rock blocks were made. Depending on their geometric properties, the rock blocks are defined in the RAMMS software and a total of 1400 rockfall simulations, 100 from each of the modeled blocks were carried out on the high-resolution DSM. Thus, the kinetic energy, jump height, velocity, and fall trajectories of each rock block were determined. According to the results, the rock blocks close to the settlements are damped without being transported very long distances. These blocks do not constitute a significant hazard since having values such as low energy, speed, and jump height. However, the rock blocks of equant shape and high volume, located on the northwest slopes above the settlements, constitute a significant in terms of hazard. These rock blocks move for long distances depending on the geometric properties of the rocks and geomorphological characteristics of the study area and their energy is absorbed in contact with houses, roads, etc., structures, or in places where the slope decreases on the topography. To prevent the danger of rock blocks in this area, retaining walls 142 m long and 1.5 m wide was created as a draft model. According to the results of these models, it was determined that while a 5 m high retaining wall in areas close to the source of rock blocks, a 3 m high retaining wall far from the source areas stops the progress of the rock blocks. © 2022, Hacettepe Universitesi Yerbilmleri.
