Challenge Problems
Push your limits with advanced challenges
You are designing a new irrigation channel in variable sediment conditions. Explain step-by-step how you would approach the design, including discharge estimation and adjustments.
💡 Hint: Start from discharge and think about its effects on each subsequent design step.
Given a silt factor of 1.5 and an estimated discharge of 20 cumecs, calculate the channel's velocity, area, perimeter, and slope using Lacey’s equations. Show step-by-step workings.
💡 Hint: Break down each calculation to avoid confusion and remember the units!
