Subcritical flow is dominated by gravitational forces and behaves in a slow or stable way. It is defined as having a Froude number less than one. Supercritical flow is dominated by inertial forces and behaves as rapid or unstable flow.
Videolar A supercritical flow is a flow whose velocity is larger than the wave velocity. The analogous condition in gas dynamics is supersonic speed. |

If Fr is greater than 1.0, flow is supercritical; if it is under 1.0, flow is subcritical. Fr is 1.0 for critical flow conditions. 3. |

(c) subcritical flows are controlled from downstream (e.g. reservoir) while supercritical flows have upstream control (e.g. spillway and weir); (d) |
The smaller velocity is sub-critical (ie, $ {\rm Fr}<1$ ), whereas the larger velocity is super-critical (ie, $ {\rm Fr}>1$ ). |
