Short summary

This paper is devoted to the SCN-CN method. The aim of the study was to derive empirical regional runoff CNs based on rainfall and discharge measurements for selected region in Slovakia. The CNs were treated as a random variable and were divided into three classes (I,II and III) with percentiles limits (0.10 and 0.90) of their distribution. A regional relationship for estimating coefficient λ was proposed. Finally, empirical regional runof curves with coefficient λ were derived.
