1.5. Deep Water Conditions

Try these first

1. 1.

   What is velocity potential?

   Hint

   Relates to fluid speeds.

2. 2.

   Define horizontal displacement.

   Hint

   Think about how waves travel.

3. 3.

   What type of orbit do water particles follow in deep water?

   • Elliptical
   • Circular
   • Spiraled

   Hint

   Think about the analysis we led.

4. 4.

   True or False: Displacement in shallow water is typically less complex than in deep water.

   • True
   • False

   Hint

   Recall our discussion on water depth effects.

5. 5.

   If you were to design a coastal structure, how would the knowledge of circular particle motion in deep water influence your design?

   Hint

   Consider the interaction of waves and structures.

6. 6.

   Experimental waves show particle trajectories becoming elliptical when moved from deep to shallow water; derive the changes in displacement expressions.

   Hint

   Focus on parameters changing with water depth.
