Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the formula for calculating the velocity in Lacey's equation?

  • V = k * f^(1/2) * R^(2/3)
  • V = Q/A
  • V = P/Q

💡 Hint: Recall how velocity interrelates with silt and hydraulic conditions.

Question 2

True or False: The Silt Factor is related to channel design but not to sediment size.

  • True
  • False

💡 Hint: Think of the definition of the silt factor in context.

Challenge Problems

Push your limits with challenges.

Question 1

If you are designing a channel with a mean sediment size of 2mm, what is the silt factor? How would this affect the channel’s velocity?

💡 Hint: Use the silt factor equation to find your answer.

Question 2

A channel is found to have a discharge of 10 m³/s with a velocity of 2 m/s. Calculate the area and describe how changes in area affect the design.

💡 Hint: Identify what happens when the area is adjusted in channel properties.
