Found that gully erosion covers the entire area of the study land. On 68.3% of the area the dissection is 2.0...7.0 km/km2 and density of gullies in some places reaches up to 15.5 pieces/km2. The average annual growth of ravines in length is 0,34...7.48 m, a maximum width is 0.20...2.48 m, depth – 0,10...Of 1.16 m. The intensity of development of gullies is influenced by their catchment area. Of the 79 gully systems that have a small catchment area from 0.02 to 0.47 km2, only 4 has the degree of dissection is less than 1.0 km/km2 and in 36 gully systems – 5.0...7.5 km/km2, a 12-year – from 7.5 to 10.0 km/km2, 4 ravines – from 10.0 to 15.0, and the one ravine system has more than 15 km/km2. The degree of dismemberment of individual gully systems is dependent on their catchment area, which is associated with the conditions of their stay.
