ASSESSMENT OF EROSION HAZARD OF THE WATERSHED OF THE KARABULA RIVER IN THE KRASNOYARSK KRAI FOR CONSTRUCTION DEVELOPMENT
The relevance. The implementation of economic activities in the southern taiga regions of the Krasnoyarsk Krai faces serious difficulties in terms of almost complete lack of up-to-date, accurate geospatial information about hazardous processes and phenomena. Obtaining such information about the curr...

The main aim of the research is to outline zones with different degrees of susceptibility to water erosion. Methods. Firstly, we prepared the electronic vector map of the catchment boundaries. Secondly, we developed the list of geomorphological, hydrological, geological, and climatic factors determining the intensity of erosion processes. We compiled thematic maps according to these parameters. Thirdly, we carried out the assessment of the weight of each factor in the occurrence and development of erosion processes by the Analytical hierarchy process. Finally, as a result of the overlay of weighted thematic maps for each factor, we created the final forecast map with the allocation of zones with different degrees of susceptibility to erosion. Results. The upper reaches of the river, occupied mainly by deciduous forests, are the most prone to erosion, the territory of the left bank of the middle part of the river is characterized by moderate susceptibility, the lower reaches of the river, occupied mainly by larch-pine forests, are the least prone to erosion. The obtained data is recommended to be used in the design of anti-erosion measures. A digital relief model for engineering and geological zoning was created for the studied territory. The main parameters of the relief, geology, tectonics, vegetation, land cover, precipitation distribution that determine the development of erosion processes are selected, calculated and analyzed.
