宽滩河流的滩地流量在全断面中占较大比重,因此,滩地测流精度的高低对总流量有一定影响,不能忽视.目前在滩地测流中,由于测流条件差,设备又比较落后,测流操作比较困难,思想上又往往不够重视,因而测速垂线位置随意变动,主观测定死水范围以及漏测等现象经常发生,因此流量误差较大.本文介绍一种滩地流量资料的审查方法——“历年滩地流量对比图”.通过对历次大水测验成果的对比分析,找出滩地流量沿宽度的分配规律,以改正误差较大的 Therefore, the accuracy of beach flow measurement has a certain impact on the total flow, which can not be ignored.At present, in the beach flow measurement, because of the poor flow measurement conditions, the equipment is relatively backward , The flow measurement operation is more difficult, and often do not pay enough attention to the idea, so the velocity of the vertical discretional changes in the determination of the subjective determination of the scope of the backwash and leakage and other phenomena often occur, so the flow error is larger.This paper introduces a method of beach flow data review - “over the years the comparison of beach flow chart.” Through the comparative analysis of the results of the previous flood test, to find out the distribution of beach flow along the width of the law to correct the larger error
