Question 1.
What is the definition of deep water?
Show hintHide hint
Think about the ratio of depth to wavelength.
Question 2.
What is the relationship for shallow water wave speed?
Show hintHide hint
Recall how wave speed is affected by depth.
3Question 3.
What is the relationship between wave speed in deep water and water depth?
- C is depth-dependent
- C is independent of depth
- Both A and B
Show hintHide hint
Think back to how we classified deep water.
4Question 4.
True or False: In shallow water, wave speed is influenced solely by wave height.
- True
- False
Show hintHide hint
Recall the relationship C = √(gd).
Question 5.
Given a wave height of 4m and a water depth of 10m, calculate the horizontal particle velocity at the surface.
Show hintHide hint
Remember to find wave number k using the wavelength relation.
Question 6.
Discuss the role of wave depth in coastal erosion and design preventive measures using wave velocity calculations.
Show hintHide hint
Consider how higher waves translate to greater force on structures.
