Challenge Problems
Push your limits with challenges.
Question 1
A trapezoidal channel has a bottom width of 5 m, side slopes of 1:2, and a depth of 2 m. The bottom slope is 0.0015, and n = 0.01. Calculate the flow rate Q.
💡 Hint: Break down the channel dimensions step by step during your calculations.
Question 2
For a channel with variable roughness (n1 = 0.02, n2 = 0.025), find the effective Manning parameter if the sections have areas of 4 m² and 6 m² respectively.
💡 Hint: Consider how each rough section contributes to the total resistance.
