Abstract

The New Moscow territory has low gully network density: 0.045 km/km2, number of gullies per unit area – 0.09 gullies/km2. The local natural conditions – dominance of flat or gradually sloping surfaces, low topographic range, dominance of relatively resistant glacial boulder clays on the surface, large percentage of forested areas – are unfavorable for linear erosion activity. Schemes of gully network density and number of gullies per unit area based on detailed topographic maps and satellite images have shown that the northern part of the New Moscow area has largest degree of gully network development, due to a combination of factors including largest topographic ranges and steepest slopes of some river valleys (mainly along the middle reaches of the Pakhra and Desna Rivers). At present, the New Moscow area becomes intensively altered by growing human activities associated with its new development. There are already some examples of reactivation of the existing gullies and formation of new ones as a result of uncontrolled anthropogenic activities and unsustainable land use within the existing gully-balka systems in the study area.
