Determine the best hydraulic cross-section for a proposed irrigation channel with a fixed discharge of 50 m³/s. Consider rectangular and trapezoidal shapes.
💡 Hint: Consider balance between width and height for rectangular shapes; for trapezoidal, focus on side slopes!
Analyze a situation where a hydraulic jump leads to significant energy loss in a channel transitioning from a flow depth of 3 m to 1.5 m. What are the key factors to assess?
💡 Hint: Remember to evaluate flow regimes and subsequent energy transformations!
