Abstract: The flood of Huihe reservoir is composed of the water discharge from upstream Xiaohekou reservoir and the sectional flood between Xiaohekou reservoir and Huihe reservoir. This paper analyzes the flood dominated by Xiaohekou reservoir and the flood dominated by sectional flood respectively. The analysis result shows the latter combination is more disadvantageous to the flood control of Huihe reservoir, thus it is used as the design flood of Huihe reservoir.

摘要： 浍河水库的洪水由上游小河口水库下泄水量及小河口水库至浍河水库区间形成的洪水组合而成。分析以小河口水库为主、区间相应的洪水组成和以区间为主、小河口水库相应的洪水组成，认为以区间为主、小河口水库相应的洪水组合对浍河水库防洪较为不利，故以此作为浍河水库设计洪水。
