Abstract

In this paper the A. tries to find quantitative similarities between the characteristics of an open system in the self-organized criticality (SOC) state and an active gully, and to find whether SOC criteria can show a transition from activity into stability. Three scenarios were used : gully evolution is controlled by initial topography and texture, when the discharge and base level are constant; discharge is constant and the base level lowers over time; the base level is constant and the discharge changes naturally. The results of numerical simulations of gully evolution are consistent with the expectations of the SOC theory
