| Abstract: | The statistical characteristics of exponential distribution of urban short-duration rainstorm are studied when the rainstorm series are chosen by annual multi-sampling method. The moment formulas of the distribution and frequency factor formula are derived respectively, the relations between moments and statistical parameters are analyzed, the parameter estimation methods are introduced, and the limits of variation coefficient are also discussed here. |
