Application of GIS methods in soil erosion modelling
AbstractSoil erosion studies are of great importance, not only from a scientific, but also from a practical point of view. The most widely used assessment method is the application of the Universal Soil Loss Equation (USLE). Three calculation methods are shown in the paper. The first method is only based on the USLE, whereas the two other calculation methods represent different estimations of soil loss by the USLE. In each case, soil loss assessment was carried out by GIS methods. ARC-INFO is used for the storage of the data layers on each factor controlling soil erosion. The main advantage of the GIS methodology is in providing quick information on the estimated value of soil loss for any part of the investigated area. The results obtained by the different calculations are slightly different. An evaluation of the results and of the methods is given in the discussion.
