Abstract

On the basis of exponential Gamma distribution, this paper presents a model consisting of 11 kinds of distribution curves for the first time. The model contains several frequency curves used commonly in China and other countries, for example, Pearson type-3 distribution, Kritsky and Menkel (USSR) distribution, Logarithmic normal distribution, and so on. Through dealing with parameters, the model may be applicable to the hydrological extreme values of different climate regions, and has very strong flexibility. In this paper, a real case study using flood datum of 240 different hydrological stations in China is submitted and the calculating results are satisfactory.
