Cross profiles of a river
WebCross-sectional area To calculate this you use the formula below: Cross sectional area (m2) = Width of river (m) x Mean depth of river (m) 4. Velocity To measure velocity we use a flow meter. Using the flow meter measure the speed of the river flow at 5 equally spaced points across the channel.
