标准范围

ISO 9123:2017规定了确定间歇或连续出现可变回水的河段水位-水位-流量关系的方法。测量仪表高度需要两个测量站，一个基准基准仪表和一个辅助仪表。为了将额定值校准到本文件要求的精度，需要进行多次放电测量。本文件未详细描述额定曲线的编制。注:有关准备额定曲线的更详细说明，请参见ISO 1100-2中描述的方法。

ISO 9123:2017 specifies methods for determining stage-fall-discharge relationships for a stream reach where variable backwater occurs either intermittently or continuously. Two gauging stations, a base reference gauge and an auxiliary gauge are required for gauge height measurements. A number of discharge measurements are required in order to calibrate the rating to the accuracy required by this document.The preparation of rating curves is not described in detail in this document.NOTE For a more detailed description of preparing rating curves, see the methods described in ISO 1100？2.
