Question 1
What is the formula for calculating discharge using Manning's equation?
- Q = (1/n) AR^(2/3) S0^(1/2)
- Q = nAR^(1/2) S0^(1/3)
- Q = n(A^2/P)^(1/3) S0^(1/2)
💡 Hint: Identify the variables: Q is discharge, n is roughness coefficient.
Question 2
The hydraulic radius is defined as?
- True
- False
💡 Hint: Think about the flow configuration.

Challenge Problems
Push your limits with challenges.
Question 1
A trapezoidal channel has a bottom width of 8 meters and depth of 2 meters, side slopes of 1:1. Calculate the discharge if n=0.013 and slope is known.
💡 Hint: Ensure you calculate the hydraulic radius correctly.
Question 2
Using the principles of a circular channel, derive the expression for the wetted perimeter given a half circle depth, and apply it to find discharge.
💡 Hint: Be careful with angle calculations to avoid errors with trigonometric functions.
