Challenge Problems
Push your limits with advanced challenges
A rectangular open channel has a width of 5 m and a depth of 2 m. Calculate the flow velocity in the channel if the slope is 0.001 and the Manning’s roughness coefficient is 0.02. Use Manning's equation for your calculation.
💡 Hint: Remember to calculate area, wetted perimeter, and hydraulic radius first.
Consider a trapezoidal channel where the bottom is 4 m, side slopes are 1:2, and the depth is 3 m. Calculate the area and the flow rate given that the slope is 0.002 and n is 0.015.
💡 Hint: Focus first on determining area and wetted perimeter.
