Popis: The aim of the research was the verification of Euler type II model rainfall used so far in modeling storm water drainage operation in Poland. Rainfall data from measurement stations in Wroclaw were used. For further analysis, rainfalls were selected on the basis of exceedance frequencies. Rainfalls were grouped with the use of cluster analysis: Ward and k-means methods. Especially the k-means method has proven to be useful for selecting precipitation in terms of hyetographs’ shapes. On the basis of clustering results, 51 precipitation were selected for verification of Euler type II standard. The statistical analysis of hyetographs shapes similarity was based on 6 parameters defined in the paper. The comparative analysis revealed that, despite some discrepancies, Euler type II model rainfall is suitable for the description of rainfall in tested station.
