【 摘 要 】

There are several formulated methods for determining of calculative stormwater flow rates in the sewage system. Three basic characteristics can be attributed to rainfall, i.e. duration, intensity and frequency. The flow rate in storm drainage network is mainly dependent on the intensity of the rain. The main parameter in the IDF curves is rainfall intensity, which is a measure of rain falling in a given time. Extremeness of a rainfall event depends on the duration of rainfall. For this reason, Intensity-Duration-Frequency (IDF) curves are extensively used in water resources engineering. This paper is focused on developing new IDF curves using three models: Dub model, Blaszczyk model and Reinhold model in the Kosice region. From the calculated values of intensities, it is clear that the relations used in Slovakia and Germany have brought very similar results of intensities, but intensity calculated according to Blaszczyk model, used in Poland equals to quarter amount.
