摘要
采用传统的同频率地区组成方法、基于copula函数的条件期望地区组成方法和最可能地区组成方法,对湘江流域洪水地区组成拟定多种设计洪水地区组成方案进行研究,经过各方案成果对比分析,推荐采用条件期望地区组成方案,为湘江流域水利水电工程和防洪系统工程的建设提供设计依据。
The research on the flood regional composition of the Xiangjiang River Basin was carried out with different methods, such as the equivalent frequency composition method, conditional expectation regional composition and most likely regional composition methods based on Copula function. Five flood regional composition schemes were worked out. After comparing the results, the conditional expectation regional composition scheme was recommended. The research contributed the basic for water conservancy and hydropower engineering and flood control system eonstruction of the Xiangjiang River Basin.
