Interactive Quizzes

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

Question 1

What equation represents the wave speed in open channels?

  • c = g/y
  • c = √(g * y)
  • c = g * y

💡 Hint: Remember how wave speed is defined based on depth and gravity.

Question 2

True or False: A Froude number greater than 1 is associated with subcritical flow.

  • True
  • False

💡 Hint: Reflect on the definition of subcritical vs supercritical flow.

Challenge Problems

Push your limits with challenges.

Question 1

A large water body experiences waves with speed 5 m/s in a depth of 3 m. Calculate gravity, and discuss how this gravity might affect aquatic life compared to Earth.

💡 Hint: Consider how gravity influences not just waves but overall ecosystem viability.

Question 2

For a river 2 m deep flowing with a wave speed of 6 m/s, compute the minimum current speed to maintain downstream flow of waves without upstream movement. Discuss implications for building fisheries.

💡 Hint: Use the relationship founded in our wave dynamics discussion to guide your estimation.
