摘要：
The paper presents the method for model formation to describe the maximum rainfall depth in Wroclaw for practical applications. Two models have been formulated: a probabilistic model for rainfall frequency range from C = 1 year do C = 100 years, and a physical model for frequency range from C = 1 year do C = 0.1 year. The probabilistic model can be used for dimensioning and modeling effects of sewage or combined sewage systems, for the required EN 752 standard for drainage area. This model, due to the time range of rainfalls (up to 3 days) can be also suitable for determining the volume of the storage reservoirs. The physical model, in turn, allows determination of storm overflows number per year.
