Article represents the calculation of the long-term average annual soil loss using the universal soil loss equation (USLE) in the model river basin. Soil loss will be assessed with respect to land use (in the categories: arable land, vineyard, garden, orchard and permanent grassland) and slope (in the categories: less than 12°, 12° ? 20° and more than 20°). There is a Slovak technical norm: Hydromelioration ? Erosion control protection of agricultural land. Based on this norm land users must comply with the delimitation criteria for the intervention of agricultural and forest land. It means that: A) slopes steeper than 12° shall not be used for growing crops and shall be grassed, B) slopes steeper than 20° shall not be used as grassland and must be afforested. Model river basin will be evaluated on the basis of these criteria. The current situation will be described. The new land use distribution will be modelled according to the results of the delimitation criteria. A detailed balance before and after will be processed. We try to deduce the consequences that may result from management in the model area due to non-compliance with the erosion control rules.
