Normal depth in open channel flow is the depth of flow in the channel ____________________?
Correct answer: A. Corresponding to uniform flow
- A. Corresponding to uniform flow
- B. Measured normal to the channel bed
- C. Corresponding to steady flow
- D. None of these
Explanation
Normal depth is the depth corresponding to uniform open-channel flow, where the depth and velocity remain constant along the channel. Steady flow only means conditions do not change with time and need not be uniform spatially.
