黄河干流洪水特征值的沿程变化分析

Analysis of Variation of the Flood Characteristics along the Huanghe River

根据黄河干流十余个控制性水文站的系列资料所计算的洪水特征值,作者进行了沿程变化分析,结果表明:它们的变化规律与各河段的产汇流条件、暴雨特性密切相关。这一成果可作为黄河干流水利水电工程及其它国民经济部门设计洪水计算成果合理性检查的参考依据。

The flood characteristics are calculated on base of the serial records of ten odd gauging stations on the Huanghe River and their variation along the river is analysed. It is found that the variation obeys a certain regularity and is closely releted to the conditions of runoff yeild and influx as well as storm characteristics. This result can be used in checking calculation of design floods for engineering projects on the river.
