Question 1
What happens to wave speed when flow depth increases?
- It increases
- It decreases
- It stays the same
💡 Hint: Think about how gravity and depth interact.
Question 2
True or False: In subcritical flow, disturbances can propagate upstream.
- True
- False
💡 Hint: What does the Froude number indicate about these flows?

Challenge Problems
Push your limits with challenges.
Question 1
Consider a canal where the flow depth is 2 meters. Calculate the wave speed and explain how changes in flow depth would affect it.
💡 Hint: Think about how the value of y changes the wave speed.
Question 2
Design a scenario where the Froude number is equal to 1. What happens to disturbances in this flow state?
💡 Hint: Reference the balance of forces in critical flow.
