The characteristics of critical flow are:
(i) The specific energy and specific force is minimum for the given discharge.
(ii) The Froude number is equal to unity.
(iii) For 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 a small slope.
(v) Flow at the critical state is unstable.
