ABSTRACT
Evaluation of surface erosion risk according to be Masoudi and Pathwardhan method was carried out in the Mątny stream basin of area 1,47 km2, located in the Gorce Mountains. The method is based on nine parameters (soil erodibility factor, soil depth, slopes, rainfall intensity, yearly rainfall, ratio of uncovered soil, ratio of plant cover, state of water erosion, geological background), which were grouped in five classes, regarding boundary values, and then depending upon possibility of erosion occurrence in future. A model allows to determine areas maps presenting percentage risk of water erosion. Parameters for the model were fully identified based on methods and databases covering GIS techniques. In the analyzed basin on more than half of the area were below 50%. The used method of erosion risk evaluation may be supplementary for the known very well method elaborated by the Józefaciuk.
