Float method discharge measurement
WebUse a marked rod, a yard or meter stick to measure the depth at regular intervals across the stream. Five depth measurements are typical but more is better, especially in larger streams. Average your cross-sectional areas (A): Using the average area and corrected velocity, you can now compute discharge, Q. See example below: Float-Area Method Web1.
