准确的洪水频率和量级估计在洪水风险管理和减少损失方面具有关键作用。在美国，对数皮尔逊Ⅲ型（LP-Ⅲ）分布的矩量法参数估计在设计洪水计算中得到了广泛的应用。自1967年第一版洪水频率准则（15号公报）发布以来，1982年至今一直采用17 B号公报修订版。一个新版本的洪水频率指南，公告17 C，正在编写，即将问世。在当前的研究中，我们分析了即将发布的Bulletin 17 C的新功能，并介绍了应用其新功能的案例研究。从所呈现的结果中，我们看到了我们可以学习的新设计洪水频率准则中的关键组成部分。
Accurate flood frequency and magnitude estimation has a critical role in flood risk management and damage reduction. In United States, Log Pearson Type-III (LP-III) distribution with method of moments for parameter estimation has been uniformly and consistently employed in estimating design floods. After the first version of flood frequency guidelines (Bulletin 15) was published in 1967, the revised version Bulletin 17B has been employed since 1982 up to now. A new version of flood frequency guidelines, Bulletin 17C, is prepared and about to come out soon. In the current study, we analyzed the new features of the upcoming Bulletin 17C and presented case studies applying its new features. From the presented results, we see what critical components in the new design flood frequency guideline we could learn.
