Float method discharge measurement
http://www.mygeodesy.id.au/documents/Stream.pdf 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.
