[1] Modelling of winter erosion processes in the small cathment lubazhikha / V. Demidov, G. Ollesch, M. Volokitin et al. // Proceedings of the 10-th International symposium on river sedimentation. August 1-4, 2007, Moscow. Russia. — Vol. 1. — Moscow, 2007. — P. 174–182. Erosive processes on sloped grounds lead, on the one hand, to the infringement of the soil over, and on the other hand, to the contamination of other environmental with the products of surface runoff and the washout of soil. In is necessary to have reliable mathematical models for forecasting the processes of erosion at the catchment scale. From these positions the Russian-German project “Erosion” in the bilateral program “Volga-Rhine” has been developed and was realized. One of the results of joint German and Russian group of scientists was the modeling system IWAN (Integrated Winter Erosion and Nutrient Load Model). This model allows the prediction of soil erosion during spring snow melting which was identified by catchment monitoring to be the major trigger for erosion. Application and calibration of model was conducted with monitoring data from 2003 to 2005 for the catchment of the small river Lubazhikha (18.8 km2), located approximately 100 km south of Moscow. The dominant soil type is a gray forest soil. 53% of the area of the Lubazhikha catchment is used agriculturally.
