There are many reservoirs that can no longer perform their design functions because much of their original active storage volume has been filled by sediment. Geographic information systems (GIS) offer a powerful tool for predicting future scenarios about reservoir siltation processes. The aim of this paper was to assess the erosion intensity in the Tisovec stream catchment (Slovakia) using the Universal Soil Loss Equation (USLE) in a raster geographic information system environment. Through GIS also the prediction of the Klusov reservoir silting with eroded soil particles in dependence on the crop rotation applied in the catchment was displayed graphically. Prediction of reservoir silting using GIS shows that this reservoir should became silted to 30 % in following 15 years when growing less suitable plants in the Tisovec stream catchment and to 16 % with growing plants with better erosion control effect.
