The characteristics of critical flow are
(i) The specific energy and specific force are minimum for the given discharge.
(ii) The Froude number is equal to unity.
(iii) For a given specific energy the discharge is maximum at the critical flow.
(iv) The velocity head is equal to half the hydraulic depth in a channel of small slope.
(v) The velocity of flow in a channel of small slope with uniform velocity distribution, is
equal to the celerity of small gravity waves (C gh = ) is shallow water caused by local
disturbance.
(vi) Flow at the critical state is unstable.
Critical flow may occur at a particular section or in the entire channel, then the flow in the channel is called "Critical flow".
yc = f(A,D ) for a given discharge.
For a prismatic channel for a given discharge the critical depth is constant at all sections of a channel. The bed slope which sustains a given discharge at a uniform and critical depth is called "Critical slope Sc". A channel slope causing slower flow in sub critical state for a given discharge is called "sub critical slope or mild slope". A slope greater than the critical slope is called steep slope or super critical slope.

Critical depth is a term used in fluid mechanics to describe the depth of flow in an open channel at which the specific energy of the flow is at a minimum for a given discharge. This is an important concept in hydraulic engineering as it helps to determine the optimal flow conditions for a given channel.
Explanation:
Specific energy is the energy per unit weight of fluid and is given by the sum of the depth of flow and the velocity head. Specific force is the force per unit weight of fluid and is given by the product of the depth of flow and the specific weight of the fluid.
At critical depth, the specific energy of the flow is at a minimum for a given discharge. This means that the depth and velocity of the flow are at an optimal level for the given discharge. At this point, the flow is said to be in a state of critical flow.
The discharge is maximum for a given specific energy at critical depth because the flow is at an optimal state for the given discharge. This means that any increase or decrease in the discharge would result in a change in the depth and velocity of the flow, which would in turn change the specific energy of the flow.
On the other hand, the discharge is minimum for a given specific force at critical depth because the specific force is proportional to the depth of flow. This means that any decrease in the depth of flow would result in a decrease in the specific force and hence a decrease in the discharge.
Conclusion:
In conclusion, critical depth is an important concept in hydraulic engineering as it helps to determine the optimal flow conditions for a given channel. At critical depth, the flow is said to be in a state of critical flow, and the discharge is maximum for a given specific energy and minimum for a given specific force.
