Aspects regarding soil erosion spatial modeling using the USLE / RUSLE within GIS

The present study refers to soil surface erosion and applies the Universal Soil Loss Equation within GIS in order to test certain methods of quantification for the control factors, as the USLE / RUSLE imply. The models’ testing implies the comparison of estimated values with the ones measured for 2 small hydrographic basins placed in the Curvature Sub-Carpathians, tributary to the Zăbala River. At the same time the scientific paper includes the application of USLE model for the sterile terrigenous masses situated in the former sulphur quarry up in the volcanic Mountains of Calimani.
