Challenge Problems

Push your limits with challenges.

Question 1

Using the concepts discussed, calculate how wave motion changes if the seabed is no longer horizontal but has a slope determined by a function h(x). Provide the equation governing the new wave motion.

💡 Hint: Apply the same principles but consider gradients introduced by the sloping seabed.

Question 2

Discuss the effects of assuming that pressure at the free surface is not uniform. What complications might arise in the dynamic boundary conditions?

💡 Hint: Consider how stability and consistency in water surface pressure impacts flow.
