Fully distributed physically based event orinted rainfall-runoff-soil erosion model Erosion-3D was developed at the Technical University in Freiberg (Saxony, Germany) by team of Jürgen Schmidt. One of the main advantages of this model is quite narrow set of input parameters that allows for easy set-up of the model. Most of the input parameters are soil and environment variables measurable by standard sciantific equipment. The two calibration input parameters that need to be found out through inverse modeling are "skin factor" (controling the infiltration rate and consequently the runoff rate) and "erodibility" (controling the soil surface resistance to provide siol particles to be transported with the downstream surface flow).
"The Catalogue of input parameters" (Michael, 2000) was created to provide access to calibration and other parameters needed for practical use of the model. The original german parameters catalogue was derived for saxony and it was recently validated and appended for use in czech conditions within project No. QK1810341 „Creating a national database of parameters for the mathematical simulation model EROSION-3D and its standardization for routine use in the Czech Republic“ of the National Agency of Agricultural Research of Czech Republic. The original catalogue does not provide parameter values for some conditions combinations common in Czech Republic. Especialy it lacks in the set of available agricultural crops and functional structures for generalization of the specified conditions. New catalogue structure was developed that allows for multi-level hierarchical agregation of the input conditions and the original data was transformed into it and supplied with czech nomenclature.
