对实测的洪峰流量进行合理性分析是我们水文工作中经常遇到的问题。这种合理性分析常用的有两种方法:一是对构成洪峰流量的其它参数因子,如流速、面积等实测数据进行合理性分析,进而推断出实测流量是否合理,其二是通过对照上下游同次洪水过程的洪峰流量、洪水总量及径流系数等参数是否平衡合理来推断实测洪水资料的准确性及合理性。在对东洲河东洲水文站“95·7”特大洪水中实测的最大洪峰流量(4210 m~3/s)的合理性分析中,我们采用了多种方法进行分析和验证。
The reasonability analysis of the measured peak flow is a problem often encountered in our hydrological work. This rationality analysis commonly used in two ways: First, constitute the peak flow of other parameters, such as flow rate, area and other measured data to conduct a reasonable analysis, and then infer the measured flow is reasonable, and the second is by comparing the upstream and downstream The flood peak flow, flood volume and runoff coefficient of the same flood are balanced and reasonable to infer the accuracy and rationality of the measured flood data. In the reasonable analysis of the maximum peak flow (4210 m ~ 3 / s) measured at the Dongzhou River hydrological station “95.7 ” extra-large flood, we used a variety of methods to analyze and verify.
