Monitoring of a completed breakwater normally includes

  • A.bathymetric and above water survey of the armour profile
  • B.measurement of the salinity of the water surrounding the works
  • C.recording the number of vessels passing each day
  • D.sampling the sediment on the adjacent beach only

Answer: A

Correct answer: bathymetric and above water survey of the armour profile

Monitoring means measuring the shape of the structure and comparing it with the as-built and previous surveys, so that settlement, armour displacement and toe scour show as trends rather than as surprises. The underwater part matters as much as the visible - the toe is where damage usually begins - which is why bathymetric survey is included as a matter of course.
