ИСТИНА

The construction of mountain sports resorts contributes to the activation of denudation processes due to the elimination of vegetation cover, cutting slopes and the movement of significant volumes of soil and bedrock on the slopes. The construction of a mountain cluster of infrastructure facilities for the 2014 Winter Olympics on the slopes of the Aigba Ridge began in the second half of the 2000s. This led to the intensification of various erosion and slope processes both directly on the construction sites and on the slopes of the catchments and in the watercourses within which the construction work was carried out. The task of the study was to assess changes in the areas of activation of slope processes within the 25 km2 polygon, within which the mountain cluster was created, their subsequent development after the completion of construction in 2014 and until 2022, as well as detailed monitoring of the relief transformation due to the active development of erosion-accumulative processes in two key areas
