推理公式中汇流参数对洪水计算的影响分析

Analysis of the Influence of Confluence Parameter in Inference Formula on Flood Calculation

在我国小型水利水电工程设计的洪水计算中,水科院推理公式法使用最广,其汇流参数m值是推理公式计算洪峰流量的重要参数,本文用具体计算实例,通过对m取值对洪水计算结果影响的定量分析,说明该值在洪水计算中的重要性,并推荐一种检验m取值合理性的简单方法。

In the flood calculation of the design of small water conservancy and hydropower engineering in China, the inference formula method of IWHR is being widely used, in which the concentration parameter m value is an important parameter in rea- soning formula to calculate peak flow. With calculation instance in this paper, and through quantitative analysis of effect of the m values on flood calculation results, the paper indicates that the value is important in flood calculation, and recommends a sim- ple verification method of m value.
