State whether the following is true or false.
A doubling of breaking wave height roughly quintuples the longshore transport rate.

  • A.True only at large scales
  • B.False only at small scales
  • C.True
  • D.False

Answer: C

With transport varying as height to the power of two and a half, doubling gives a factor near five and a half. This steep dependence means a few storms can dominate the annual total. Design must consider the distribution, not just the mean.
