Challenge Problems
Push your limits with challenges.
Question 1
A river has varying widths and depths across sections, with flowing conditions listed below: 1st section (width 2m, depth 1m, n=0.035); 2nd section (width 3m, depth 2m, n=0.025). Calculate the total flow rate using Manning's equation.
💡 Hint: Ensure careful tracking of each section's flow.
Question 2
You have a square channel 5m by 5m, with a slope of 0.002 and a Manning's coefficient of 0.03. Determine the flow velocity and total discharge.
💡 Hint: Be systematic in your calculations.
