Challenge Problems
Push your limits with challenges.
Question 1
A rigid boundary channel has a hydraulic radius of 0.4 m, a slope of 0.015, and a roughness coefficient of 0.05. Calculate the velocity using Manning’s formula.
💡 Hint: Break it down: first find R^(2/3) and S^(1/2), then divide by n.
Question 2
Discuss the consequences of allowing sediment transport in a rigid boundary channel. How would it affect design and water flow?
💡 Hint: Consider effects on channel shape and flow characteristics over time.
