Practice Questions

Question 1

Given significant wave height $H_s=2\,\mathrm{m}$ and period $T=8\,\mathrm{s}$ in deep water, calculate the wave energy flux per meter of crest using $P=\frac{\rho g^2 H_s^2 T}{64\pi}$, where $\rho=1025\,\mathrm{kg/m^3}$ and $g=9.81\,\mathrm{m/s^2}$. Show calculation.

Question 2

A storm event erodes a 150\,m long section of dune by an average height loss of 0.6\,m across a 4\,m width. What is the total volume of sand eroded? Show calculation.

Question 3

What is the primary meteorological driver of storm surges during tropical cyclones?

Question 4

Which coastal feature consists of rhythmic, arc-shaped shoreline indentations formed by self-organization of swash flows?

Question 5

After removal of an offshore breakwater that previously blocked waves, what immediate morphological change is expected in the littoral zone?
