Open-channel flow, or gravity flow, occurs when the water surface is at atmospheric pressure, which creates a free surface. ... Open-channel flow, however, is more complex than closed-conduit flow since the cross-sectional flow area is not constant. 1, record 1, English, - cross%2Dsectional%20flow%20area
