Question 1
Consider a channel with a discharge of 20 m³/s and sediment size of 1 mm. Calculate the silt factor and subsequent channel characteristics, including velocity, area, wetted perimeter, and slope.
💡 Hint: Break down each component step-wise to tackle the problem efficiently.
Question 2
Discuss how different sediment sizes can affect the slope estimation in Lacey’s design procedure, providing specific examples.
💡 Hint: Consider how the flow dynamics change with sediment size!
