According to Kennedy's theory, what is the critical velocity (V_c) for a canal primarily dependent upon?

Explanation:

Kennedy's theory of critical velocity:

• Kennedy's theory of critical velocity is a concept in sediment transport, proposing that a river's flow must reach a critical velocity to initiate erosion and transport sediment.
• Below this velocity, sediment settles; above it, erosion occurs.
• This theory helps predict the threshold for sediment movement in river channels.
• It is Nonsilting and Non-scouring Velocity.
• Kennedy did not mention anywhere that it's a maximum permissible or minimum permissible velocity.

The critical velocity suggested by Kennedy is

V0 = 0.55 m y0.64

Where,

m = critical velocity ratio

y = depth of water in the canal.
