Float method discharge measurement

WebThe discharge is derived from the sum of the product of mean velocity, depth and width between verticals. The discharge so obtained is normally used to establish a relation between water level (stage) and streamflow. Once established, this stage-discharge relation is used to derive discharge values from records of stage at the gauging station.
