Hydrometry - Measurement of liquid flow in open channels - Part 2: Determination of the stage-discharge relationship
|Publication Date:||1 December 2010|
|ICS Code (Flow in open channels):||17.120.20|
This part of ISO 1100 specifies methods of determining the stage-discharge relationship for a gauging station. A sufficient number of discharge measurements, complete with corresponding stage measurements, are required to define a stage-discharge relationship to the accuracy required by this part of ISO 1100.
Stable and unstable channels are considered, including brief
descriptions of the effects on the stage-discharge relationship of
shifting controls, variable backwater and hysteresis. Methods of
determining discharge for twin-gauge stations, ultrasonic
