Challenge Problems
Push your limits with challenges.
Question 1
Calculate the discharge for a channel with a width of 5 meters, a depth of 3 meters, an n value of 0.035, and a slope of 0.001. Use Manning's equation.
💡 Hint: Break it into manageable steps and solve each part sequentially.
Question 2
For an irregular channel, determine an effective Manning's n if you have n values of 0.025, 0.030, and 0.050 for varying surfaces.
💡 Hint: Consider the proportion of each segment in the overall channel.
