This investigation has been carried out at Badinska River watershed - one of the most famous torrents in Bulgaria. The purpose of the survey is to analyse the main erosion factors and erosion potential of territories, with a view to assess soil erosion risk and opportunity of high water formation from watershed. A methodical approach for determination and mapping of the territories in terms of the class of erosion risk with the use of GIS is applied. Assessments are made according to the “Methodology for preparing the national long term programme for protection against erosion and flooding in forestlands”. The total assessment for Badinska river watershed is “low to moderate” potential risk and “very low to low” actual erosion risk. About of 5% of the forest stock territory is with “moderate” and “moderate to high” actual risk, and the biggest part of this territory (about 63%) is in the main stream watershed above the Yaloviko tributary
