O článku:
The article is focused on mathematical modelling of the soil erosion processes on the selected areas within the Slovak Republic and Poland. The study includes the validation of the models used based on the actual measurements. The intensity of the soil erosion processes was calculated using the physically-based EROSION-3D model and the empirical USLE-SDR model. The simulations were done based on continuous rainfall events and a long-term simulation. The results modelled were confronted with the actual measurements in both areas investigated. Since a model’s validation and calibration as well as a relevant interpretation of the results obtained are the hardest and most challenging parts of any research, it is necessary to constantly enhance the techniques and methods of the calibration and validation of models, thereby deepening the knowledge of individual models. The results show the process has to be performed before the application of the models used together with the advantages and disadvantages of the physically-based and empirical models used, including a comparison and validation of the models applied.
