Rapid flow

Rapid flow

Also refered to as supercritical flow, rapid flow is distinguished from tranquil flow by a dimensionless number called the Froude number. If the Froude number is less than one, the flow is tranquil. If the Froude number is greater than one, the flow is rapid. If the Froude number is equal to one, the flow is critical. Surface waves can propagate only in the downstream direction. Control of rapid flow depth is always at the upstream end of the rapid flow region.
