DESCRIPTION:The design and operation of structures and vessels
  in the coastal zone is largely dependent upon the
 ir ability to withstand large environmental loads.
  In most cases\, critical environmental loading ar
 ises from the largest waves that hit coastal asset
 s. As such\, an accurate description of the charac
 teristics of these largest waves is a top priority
  for scientists and engineers. This talk will addr
 ess the statistical description of large storm wav
 es in the coastal zone by analysing extensive data
 sets of (a) laboratory measurements conducted in t
 he Hydrodynamics laboratory at Imperial College Lo
 ndon and (b) field measurements from fixed offshor
 e platforms in the North Sea. In doing so\, the ke
 y physical mechanisms that lead to the formation o
 f extreme waves will be identified. Specifically\,
  new findings about the competing effects that non
 linear wave-wave interactions and wave breaking ha
 ve on the statistical distribution of waves will b
 e presented. These will be used to derive new stat
 istical distributions for waves that are applicabl
 e to a wide range of water depths. Finally\, I wil
 l discuss the implications of using the new\, impr
 oved models instead of existing models in the engi
 neering design and assessment of offshore and coas
 tal assets.
