Ravine denudation on hollow downslopes

Abstract

Ravine denudation on hollow downslopes V. Tarasov, leading researcher, National Scientific Center «Institute for Soil Science and Agrochemistry Research named after O.N. Sokolovsky» 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.
