Estimation of Erosion Danger Lands of the Reclamation Fund in Georgia

Abstract

Erosion danger of lands of the reclamation fund in Georgia was studied by means of the Universal Soil Loss Equation (USLE) (Wischmeier and Smith, 1978), which was modified in the Problem Lab of Soil Erosion and River Bed Processes of Moscow State University (Anonymous, 1982). By the investigation was established that average annual potential soil loss, which was counted by means of USLE, is 10,5 % less than real loss of soil. If for the calculation of the potential soil loss we use only rains which provoke soil erosion, the difference between real and counted soil losses is only 1.77 % i.e. exactness of soil erosion forecast increases 5-6 times.
