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. WebIf my float measurements gave me an average surface velocity of 2.2 ft/s (feet per second), then I can calculate the CFS discharge by using the discharge formula below. CFS = Area x Velocity CFS = 4.86 x 2.2. Adjusted Velocity (see note below) = 2.2 ft/s x .85 = 1.87 … As the water level rises or lowers, the float goes up and down, thus turning the …
