A useful method to evaluate the effectiveness of soil-erosion models is to compare the models' soil-loss and runoff calculations with measured data from experimental plots subjected to artificial rainfall. This study was conducted to develop a set of statistics to compare the performance of the soil-erosion models EUROSEM, WEPP, and MEDRUSH. Rainfall (six rainfall intensities, two replicates), runoff, and soil-loss data from artificial plots at two locations in Hungary were used to assess the accuracy of the different models. The soil types within the plots represented a wide range of soil properties and are soil types that are commonly used for agriculture. The results showed that the three soil-erosion models performed with varying effectiveness dependent on basic soil properties. However, statistical analysis showed the EUROSEM model to be the best for estimating soil loss in Hungary.
