Квалитативана и квантитативна процена губитака земљишта применом WaTEM/SEDEM модела

Abstract

The spatial-distributive WaTEM/SEDEM model is one of the erosion model based on the (R)USLE methodology. The use of the WaTEM/SEDEM model in estimating soil losses, sediment transport and distribution of some heavy metals and phosphorus is given through the example of one micro-catchment in the rive Rasina Basin in central Serbia. By analyzing the structure of the model, input parameters generating of the necessary layers and data require for the simulation of erosion processes are described in detail. Also, model reliability tests are explained (verification, calibration, validation, model efficiency ME). Taking into account the fact that the WaTEM/SEDEM model is underrepresented in science literature, the potential advantages and disadvantages of the model in the simulation and assessment of erosion processes are pointed out.
