Anthropogenic impact on exogenous processes in low mountains of semitropics

The paper represents the results of regular measurements of the main exogenous processes at three test sites in the low mountains of scmitropics (Central Apennines, Western Caucasus, and Tien-Shan). A set of methods included fids, benchmarks, traps, Yang method, etc. The strongest denudation (up to 2 cm/year in the West Caucasus and up to 6 cm/year in the Apennines) takes place at those parts of badlands, which were formed as a result of human activity. The total denudation is the sum of several processes, the set of which depends on lithology, relief, and climate. On the whole the denudation of the studied catchments raised 2-3 orders due to human impact in comparison with natural denudation rates.
