Ravine denudation on hollow downslopes

Abstract

The purpose. To study state and dynamics of development of gullens upon hollow nets of slope lands in land-use of modern agricultural facilities. Methods. Geomorphologic analysis of maps and geodetic methods of erosion-hydrological researches on hollows. Results. Factors influencing the loss of land on thalweg of hollows are determined and mathematical-and-statistical model of gully erosion which determines a layer of ravine denudations is elaborated. Conclusions. They consider that the layer of ravine denudation most objectively characterizes parameters of ablation on the upper parts of hydrographic network.
