Abstract

Soil erosion is a growing problem in South East Europe and is creating a hazard to soil quality, environment and biodiversity. It is well-known fact that runoff, soil erosion and as consequence sedimentation, are decreasing a reservoirs capacity and that is noticeable in the region of Polimlje, where the studied watershed belongs. This is causing the new expenses to the weak economies of the Countries of this underdeveloped area. Ecological factors, which are the basis for the calculation of soil erosion intensity, we included in the simulation model. At the level of the watershed, the use of computer-graphic methods allowed the quantification of the environmental effects of runoff and soil erosion. Maximal outflow (incidence of 100 years) from the studied watershed, Qmax, was predicted on 31 m3/s. The value of the Z coefficient was calculated on 0.271 and according to the result the watershed belongs in the destruction category IV. The strength of the erosion process is low, and mixed erosion dominates in the studied area. The calculated soil losses were 277 m³ per year for the watershed, specific 115.5 m³/km2 per year. We have not evaluated proposed anti-erosion measures in the area because they have not been put into practice. This study shown that IntErO model is a useful tool for researchers in calculation of runoff and sediment yield at the level of the river basins in the South East European region.
