This paper provides results of evaluating of potential and actual water erosion within area of Urpin and Laskomer in Banska Bystrica located in rugged terrain on limestone bedrock which are affected by wide range of water erosion. In order to determine the amount of taken soil two various methods was used and results of both was compared. The first is photogrammetric method, which determine potential water erosion in GIS environment. The second method applied in research was volumetric method, which uses clinometer wood planks sets with added informations about location of founded plots from GPS receiver. Measured values was graphically displayed in the form of cross sections in individual profiles and longitudinal sections showing the entire course of erosion score. Through mutual comparison of these methods and their achievements we want to highlight the risk of water erosion of recreational land use in the event of damage to vegetation cover, improper care, possibly inappropriately designed technology of access development of forest stands or intolerable load (anthropic pressure) caused by amount of visiting holidaymakers.
