Question

For a given discharge, the critical flow depth in an open channel depends on

• A. Channel geometry only
• B. Channel geometry and bed slope
• C. Channel geometry, bed slope and roughness
• D. Channel geometry, bed slope, roughness and Reynolds number

Hint:

Remember: \[ \boxed{\text{Critical Depth}} \] depends on \[ \boxed{\text{Discharge + Channel Geometry}} \] whereas \[ \boxed{\text{Normal Depth}} \] depends on discharge, bed slope, and roughness.

Answer 1

The Correct Option is A
