Discussion

Coastal squeeze is a management concern principally because

  • A.navigation channels become deeper than they need to be
  • B.the estuary behind the defence becomes noticeably deeper
  • C.designated intertidal habitat is lost between the sea and a defence
  • D.the defence itself becomes considerably cheaper to maintain over time

Answer: C

The habitat cannot migrate landward and narrows until it disappears. Its loss also removes the wave attenuation that the defence itself was relying on. Squeeze therefore harms the defence as well. Habitat and engineering interests coincide here.
