2. Surface Solitary Waves

Try these first

1. 1.

   What is open channel flow?

   Hint

   Think about how rivers or streams behave.

2. 2.

   How can waves form in an open channel?

   Hint

   Consider physical movements in a body of water.

3. 3.

   What defines open channel flow?

   • Closed channel with pressure
   • Flow with a free surface
   • Flow in a pipe

   Hint

   Think about the characteristics of natural watercourses.

4. 4.

   True or False: Steady flow means the water depth changes over time.

   • True
   • False

   Hint

   Consider how constant conditions look in a flowing river.

5. 5.

   Consider a channel in which a moving wall creates a solitary wave. Calculate the wave speed if the depth of water is 2m and the wall moves at a speed of 0.5m/s.

   Hint

   Break down the relationship and evaluate your variables correctly.

6. 6.

   If static water creates solitary waves when disturbed, analyze how changing the depth of the water affects these waves' behavior.

   Hint

   Think about how waves behave in shallow versus deep bodies of water.
