Abstract: Soil erosion damages about 35 percent of the total land area in Lithuania. Soil losses range from 4-24 t/ha/yr. The USDA-Water Erosion Prediction Project (WEPP) Model has been adapted and verified to simulate storm runoff, soil erosion, and related processes in the eastern part of Lithuania. Three years of data from small agricultural plots under various cropping systems were compared to model outputs. The results of the simulation have shown that the WEPP Hillslope Model (Version 91.5) provided reasonable annual average estimates of erosion. As new releases of the model become available, additional testing and validating will be completed for agricultural and forestry practices at the plot and watershed scale.
