適用范圍：This International Standard specifies methods for determining the velocity and cross-sectional area of waterflowing in open channels without ice cover, and for computing the discharge therefrom.It covers methods of employing current-meters or floats to measure the velocities. It should be noted thatalthough, in some cases, these measurements are intended to determine the stage-discharge relation of agauging station, this International Standard deals only with single measurements of the discharge; thecontinuous recording of discharges over a period of time is covered in ISO 1100-1 and ISO 1100-2.NOTE The methods for determining the velocity and cross-sectional area of water flowing in open channels with icecover are specified in ISO 9196.
