Probabilistic approach of the Upper and Middle Odra basin daily rainfall modeling

The aim of this study was to obtain the maximum daily rainfall descriptions based on 9 probability distributions in 12 meteorological stations located in Upper and Middle Odra river basin. Analysis included long-term period from 1961 to 2010. Regarding to AIC and BIC informational criterions Gamma distribution that appeared to be best fitted probability distribution to measurement rainfall data series. For several stations, Pareto, Weibull and generalized exponential distributions were also possible to use. For practical purposes it is necessary to carry out a similar analysis for much shorter rainfall intervals. The final evaluation of the suitability of individual probability distributions for constructing maximum rainfall probabilistic models requires further research.
