根据长江、黄河、海河及淮河的部分河段上古洪水研究工作所取得的成果 ,按水利水电工程实际洪水计算的方法 ,将有古洪水资料的洪水频率计算成果与无古洪水资料的设计洪水成果相比较 ,从参数区域协调平衡、相同控制面积下设计洪水成果等的合理性检查方面论述加入古洪水资料后其设计洪水成果的合理性 According to the achievements made in the research of the ancient floods in the Yangtze River, the Yellow River, the Haihe River and the Huaihe River, according to the actual flood calculation method of the water conservancy and hydropower project, the calculation results of the flood frequency with the ancient flood data and the design flood results of the ancient flood data In comparison with the rationality of the design flood results under the same control area, this paper discusses the rationality of the design flood results after the addition of the ancient flood data
