Abstract
As part of the development of improving methods for integrated monitoring of dangerous riverbed and slope processes, the authors worked out options for using an unmanned aerial vehicle (UAV) and specialized software in order to improve the quality of materials for field surveys of mudslide sites. The reliability of the quantitative determination of the parameters of mudflows is an urgent problem in assessing the spatial and temporal changes in the parameters of mudflow channels. The purpose of this work is to quantify the dynamics of changes in the landscape of residential areas exposed to negative impacts by determining the quantitative values of morphometric parameters of the mudflow channel and the adjacent territory before and after the passage of the mudflow. In particular, the volumes of soil carried away by the flow, as well as the volume of sediments in different sections of the mudflow transit, were determined. By comparative analysis of the results of software processing of materials from the removal of problem areas of the mudflow channel by a quadcopter, the values of the volumes of carried away soil (4376 m3, at the site of destruction by the flow of the highway) and mudflow deposits (above – 4623 m3, and below – 1788 m3 of the highway bridge) were obtained. Such an information base is indispensable in solving the problems of ensuring the safety of settlements and economic facilities from the negative impact of mudflows.
