| 摘 要： | 传统的洪水频率分析都是假定洪水资料取自某一已知分布函数的总体。这样的假定并非总是正确和适用的。本文提出了在有历史洪水情况下洪水频率的非参数核估计方法,克服了现行方法假定分布型式的局限。实际洪水资料的计算和蒙特卡罗试验表明:新方法具有较好的精度。

| Abstract: | According to the traditional flood frequency analysis, flood data are assumed to have been taken from a known distribution function as a whole. However, such an assumption is not always correct. A nonparametric kernel estimation of the flood frequency with historic information is presented in this paper. The limitation in assuming a distribution type is overcome. The new method is more accurate as can be seen from actual calculation and Monte Carlo test on the flood data. |
