Challenge Problems
Push your limits with advanced challenges
Calculate the flow profile through an uneven rectangular channel with varying slope. The channel's bottom width is 6m, discharge is 10m³/s, and Manning’s n is 0.020. How do these factors interact to determine flow type?
💡 Hint: Start by calculating the critical depth then apply Manning's equation to obtain normal depth.
Design a channel that maintains a steady flow of 5m³/s with minimal fluctuation in depth for a width of 3m. Propose an equation considering bed slope and roughness coefficient.
💡 Hint: Ensure your flow meets conditions for both slopes and depth.
