Risk assessment of manifestation of geomorphological processes on the slopes of the Borzhava mountain range using GIS modeling methods for environmental needs determined from precise levelling

Geomorphological region Polonyna Borzhava (GRPB) is important from the point of view of environmental protection. Forestry and tourism-recreational nature management are actively developing and the construction of a large-scale wind farm project with 34 wind power plants (WPPs) with a total capacity of 120 MW is planned here. The mentioned anthropogenic activity contributes to the intensification of negative geomorphological processes and threatens the preservation of the existing sections of the Emerald network, which are of pan-European significance. The article, using GIS modeling methods, presents the results of the assessment of probable risks of the manifestation of adverse geomorphological processes within the slope geosystems of the GRPB. Based on the digital relief model created by us for the geomorphological region of Polonyna Borzhava, morphometric maps of slope steepness and exposure were compiled. A comprehensive analysis of these morphometric indicators made it possible to identify groups of slopes with varying degrees of risk of unfavourable geomorphological processes, provided that the integrity of the soil and vegetation cover is violated. The level of protection of slopes by nature reserved objects has been revealed. In order to establish environmental management and prevent the development of adverse processes within the framework of the GRBP, it was proposed to create a nature reserve institution here, introduce approaches in the forestry industry, limit the movement of tourist transport, and prevent the implementation of large-scale energy and recreational tourism projects.
