Challenge Problems
Push your limits with challenges.
Question 1
A rectangular channel has a width of 5m and a depth of 1.2m with a discharge of 2m³/s. Calculate the normal depth using Manning's equation with n = 0.015.
💡 Hint: Remember that for a rectangular channel, A = b * y, and R can be related to A and wetted perimeter.
Question 2
Describe the physical significance of \( rac{dy}{dx}\) being much less than 1.
💡 Hint: Think about flow profiles and their relationship to water depth.
