Abstract

The aim of the research was the verification ofEuler type II model rainfall used so far in modeling storm waterdrainage operation in Poland. Rainfall data from measurementstations in Wroclaw were used. For further analysis, rainfallswere selected on the basis of exceedance frequencies. Rainfallswere grouped with the use of cluster analysis: Ward andk-means methods. Especially the k-means method has proven tobe useful for selecting precipitation in terms of hyetographs’shapes. On the basis of clustering results, 51 precipitation wereselected for verification of Euler type II standard. Thestatistical analysis of hyetographs shapes similarity was basedon 6 parameters defined in the paper. The comparative analysisrevealed that, despite some discrepancies, Euler type II modelrainfall is suitable for the description of rainfall in testedstation.
