Challenge Problems
Push your limits with challenges.
Question 1
A circular channel has a flow depth of 1.2 m. Calculate the hydraulic radius if the segment's angle is 60 degrees. Use geometric properties of circular segments in your calculations.
💡 Hint: Consider the radius of the circle and trigonometric relationships.
Question 2
A trapezoidal channel has a bottom width of 6 m, a depth of 2 m, and side slopes of 1:1. Calculate the hydraulic radius and discuss how this shape would influence flood control in a region.
💡 Hint: Look at both flooding dynamics and channel hydro-dynamics.
