The subject of the study was the characteristic of the distribution and development of gullies under the influence of such an anthropogenic form of relief as a quarry. The aim of this research was to determine the ratio of linear forms of erosion of different lengths in the influence zone of the quarry. The morphometric method was used. When comparing the three sectors at the key site, it was found that the central sector, which is directly adjacent to the quarry, is characterized by a large number of gullies. It was revealed that in the central sector, gullies with a length of 40 to 50 meters account for 72.7% of the total number of linear erosion forms of this length in the entire key area. The activity of the quarry is accompanied by pruning of the slopes. The main factor forming the prerequisites for differences is the change in the local erosion base level. The results of the work can be used to assess the development of linear erosion in the area of influence of quarries.
