1) division of flood stage
洪水分期
1.
The flood events have self-similarity and fractal characteristic for certain duration,the fractal theory can be used to determine the division of flood stage.
洪峰散点序列在一定尺度范围内表现出了自相似性和分形特征,可用分形理论划分洪水分期。
2) flood in different period
分期洪水
3) seasonal design flood
分期设计洪水
1.
The recent research advance of seasonal design flood methods and the technical problems of present practice were discussed and assessed.
采用分期设计洪水是实现洪水资源化的主要方式之一。
2.
This approach provides a new way to optimize the seasonal design floods and FCWLs.
在假定分期设计洪水值的联合重现期等于防洪标准T的前提下,推导基于Frank Copula函数的分期设计洪水频率和防洪标准的关系,解决了分期设计洪水达不到防洪标准和分期频率与年频率不一致的问题,为分期设计洪水、分期汛限水位优化设计提供了一条新思路。
3.
The present seasonal design flood method is under the assumption that the seasonal design frequencies equal to the reciprocal of the flood prevention standard, which causes the return period of the design values is less than the standard.
分期设计洪水既要满足防洪标准,又能反映洪水的季节性变化特征。
4) stage design flood
分期设计洪水
1.
Based on observation data in the basin,the stage design flood at the dam site is calculated by area interpolation method,compared with the maximal value of design flood,and the quantitative relations between them are also worked out by introducing the conception of combined frequency.
根据流域资料用流域面积内差计算出坝址分期设计洪水,并与全年最大值设计洪水进行对比分析,引进组合频率概念推导两者之间的量化关系。
2.
The author discussed the necessity of adopting stage design flood for Baise Multipurpose Dam Project.
论述了百色水利枢纽进行分期设计洪水的必要性,分析了坝址上游流域的暴雨和洪水特性。
5) stage boundary of flood
分期洪水时界
6) seasonal flood control
分期洪水调度
