В статье рассмотрен опыт применения комплекса для аэрофотосъемки на базе мультироторного беспилотного летательного аппарата (БПЛА) при решении различных задач в области инженерной геодинамики, в частности, для получения количественных показателей исследуемых объектов с использованием фотограмметрического метода. Рассматривается опыт использования БПЛА при исследовании селевых процессов в предгорьях Тункинских гольцов (Россия) и эрозионных форм в пределах Улан‐Баторской агломерации (Монголия). Представлены первые результаты исследований конусов выноса селевых бассейнов и элементарных водосборных бассейнов эрозионных форм. Для изучения вышеперечисленных процессов была выполнена разномасштабная аэрофотосъемка – локальная и детальная, с использованием БПЛА. Локальная аэрофотосъемка, высота полета 100–150 м, применялась при изучении относительно крупных объектов – конусов выноса, локальных водосборных бассейнов. Детальная аэрофотосъемка, высота полета 1–30 м, использовалась как для получения данных гранулометрического состава селевых отложений, так и для построения поперечных профилей эрозионных форм. По результатам проведенной работы составлена схема рас‐ пределения аккумулятивных селевых отложений, определен гранулометрический состав крупной фракции селевых отложений. На основе созданных по результатам аэрофотосъемки трехмерных моделей фрагментов эрозионных форм построены поперечные профили этих форм.

The article reviews the experience of aerial surveys using a quadcopter DJI Inspire 1 PRO (unmanned aerial vehicle, UAV) for solving problems of engineering geodynamics. It describes the application of photogrammetry to estimate quantitative parameters of the studied objects, the experience of using UAVs to study flood processes in the Tunka valley (Russia) and erosion structures in the Ulaanbaatar agglomeration (Mongolia). The first UAV‐acquired data on debris flow alluvial fans and elementary drainage basins of erosion structures are presented. The ranges of UAV flight heights were 100–150 m and 1–30 m for local and detailed aerial photography surveys, respectively. Local surveys covered relatively large objects – debris flow alluvial fans and drainage basins. Detailed aerial photography aimed to investigate the granulometric compositions of debris flow deposits and to construct transverse profiles of erosion structures. Processed aerial photos provided a basis for a schematic map showing the distribution of accumu‐ lated debris flow deposits. The granulometric compositions of coarse fractions in the debris flow deposits were de‐ termined. Based on the survey results, 3D models of the fragments of the erosion structures and their cross‐sections were constructed.
