Wind Erosion in Russia: Spreading and Quantitative Assessment
Larionov G. A., E. L. Skidmore, and Z. P. Kiryukhina
Abstract
Wind erosion is a wide spread phenomenon on arable lands at some southern part of
Russia. Detailed description of wind erosion in the North Caucasus including synoptic
condition during dust storms, influence of relief on wind velocity, quantitative soil loss
assessment, eolian accumulative forms near the shelter belts are given. A semiempirical
wind erosion equation is also suggested. The erosion potential of winds equals the product
of cubed average wind velocity multiplied by the equation of logistic curve in order to
exclude those part of wind energy which instantaneous velocity is less than threshold
value. The methods of estimating of the main factors of erosion is described. |
