Estimating the dynamics of exogenous geological processes and understanding their controlling factors is an urgent task faced by many regions of the world. One of the methods of its solution is monitoring. The paper presents the UAV monitoring results for short-term dynamics of complex exogenous processes at five key sites in the coastal zone south of the Bratsk reservoir. The study area is a part of the platform structure in the south of the Irkutsk amphitheater, which is considered to be relatively stable in terms of geodynamics. There has been developed a methodical scheme for obtaining data series on the dynamics of complex exogenous geological processes in the coastal geosystem. A flight altitude of 50–60 m is optimal to obtain orthophotos with a resolution of 1.1–2.2 cm/px, sufficient to estimate the areal dynamics of the processes, and a DEM with a resolution of 2.6–5.4 cm/px to estimate the volumetric dynamics.The eroded coastal area at the Rassvet site was measured to be 6900 m2, which corresponds to an average erosion width of 3.45 m per linear meter of coastal length with maximum values of up to 6.51 m. A high rate of coastal erosion in the period 2021–2022 is related to the maximum water level in the Bratsk reservoir, close to the normal headwater level. The assessment of the volumetric dynamics of the coastal gullies yielded negative values, as most of the gully mouths were eroded. The secondary valley-bottom gullies (Mamontov and Barany sites) and coastal gullies (Khadakhan site) are characterized by positive dynamics both in area and volume growth (12–20 m2 and 1.3–35.0 m3, respectively). At the Khadakhan site, the volumetric growth of new and previously observed suffusion sinkholes was 0.45 m3.The obtained areal and volumetric rates of the exogenous processes can serve as a basis for their modern assessment and prediction of their development in order to prevent and reduce socio-economic risks.

The subject of the article is the development of a laboratory tester for the study of the effectiveness of propeller-engine groups (PEG) of electric unmanned aerial vehicles (UAV). The need to create such solutions is due to the fact that the development and testing of unmanned platforms in the format of prototypes and their flight tests are time-consuming and expensive processes, it is not possible to assess the limit parameters of motors and their electronic speed controllers (ESC). Hardware devices and software for testing PEG separately can reduce the cost and speed up this process, as well as make the result more optimal both in terms of technical parameters and in terms of economic efficiency. A solution has been developed that allows to measure the motor amperage, the generated thrust of PEG, the voltage on the battery, the temperature of the motor, and then calculate PEG effectiveness indicators on their basis, visualize them in graphs, and thus compare the thrust and energy efficiency of various engine-propeller groups with propellers up to 30” ‘in size’. It is shown how the test results allow you to choose the optimal solution for assembling propeller-motor groups for light and medium UAV, and optimally design unmanned platforms for airborne geophysical prospecting.

Abstract—The experience of scientific support of work on the rehabilitation of the gully on the Cape Burkhan on the Olkhon Island (south of Eastern Siberia, Lake Baikal) is considered in this article. Cape Burkhan is a unique natural monument with a recognizable landscape and a high-status tourist attraction, which is exposed to a high recreational impact. The processes of linear erosion develop in this area most intensively due to the characteristics of the lithological and geological structure and morphological parameters. The anthropogenic factor has the greatest influence on the activation of dangerous geomorphological processes, including erosional ones. As a result of the study, the comprehensive analysis of the territory was carried out: initial conditions, causes, and factors of vegetation and soils degradation, activation of erosion processes. Various approaches to the technological and biological stages of gully rehabilitation were analyzed. Detailed recommendations have been developed to reduce the recreational impact on the relief and carry out restoration work. The proposed approaches to rehabilitation can be used on other gullies on Olkhon Island and the Priolkhonskoe plateau.
