Streaming flow or tranquil flow is the flow when depth of flow in an open channel is greater than the critical depth.

Krunal said: (Feb 13, 2017)  
If the depth of water in an open channel is greater than the critical depth, the flow is also called subcritical flow (slow flow).

What is critical depth?

Avinash said: (Jan 12, 2018)  
When Froude no is less than 1 then the flow is said to be sub critical or Tranquil flow (both are same).

Siva said: (Jun 19, 2018)  
The critical depth is the depth at which Froude number =1,
F=v/√(gy) if depth is more than this it is subcritical flow or else supercritical flow.

What is the significance of critical depth?

Ali Rashad said: (Feb 7, 2020)  
The depth of water in a channel corresponding to the minimum specific energy is known as critical depth.

Rupesh said: (Apr 2, 2020)  
As of my knowledge, The flow is very slow,

Fr=1. Critical flow
Fr>1. Supercritical flow (rapid flow)
Fr<1. Subcritical flow (slow flow/Tranquil Flow)
Fr> 1.

If the depth of water in an open channel is less than the critical depth, the flow is called torrential.
