Application Of The Intero Model For The Assesment Of The Soil Erosion Intensity And Runoff Of The River Basin Dragovo Vrelo, Montenegro

Abstract

This paper presents the use of IntErO model for prediction of runoff and soil loss in the river basin Dragovo Vrelo of Polimlje, Montenegro. Physical-geographical inputs, which are the basis for calculation of soil erosion intensity, we included in the IntErO model. This allowed the quantification of the environmental effects of soil erosion. Data concerning runoff and sediment yield from the Dragovo Vrelo watershed located in the North-East of Montenegro are reported. The value of the Z coefficient was calculated on 0.393, what categorises the studied river basin in the fourth destruction category out of five. Our results suggest that the calculated maximal outflow from the river basin was 174 m3s-1 for the incidence of 100 years and the net soil loss was 3857 m³ per year, specific 335 m³km-2 per year. The strength of the erosion process is low. Because of simple and reliable identification of critical areas of soil erosion the IntErO model may be applied for sediment modelling in other river basins of the Balkan Peninsula
