THE VERIFICATION OF POWER SOILS WIND EROSION MODEL

Abstract

The results of experimental information analysis of soil blowing, published in monograph by V.M. Gendugov and G.P. Glazunov (2007), are presented in article. Calculations are realized with using introduced wind erosion “power” model. Three parameters, which possess clear physical interpretation - “threshold”, “initial quadratic” and “critical” air stream velocities, underlie in the introduced by us model instead of nondescript and unconnected empiric coefficients are ingressed in wind erosion “null-model” of V.M. Gendugov and G.P. Glazunov It is shown, that “power” model covers all area of wind erosion hazard velocities. Two dependences are proposed for wind erosion intensity calculation, one of which works in the range of wind velocities from threshold up to critical, other - in the range of wind velocities exceeded critical.
