SUMMARY:The statistics of extreme waves in the coastal zone - Ioannis Karm

DESCRIPTION:The design and operation of structures and vessels in the coas
 tal zone is largely dependent upon their ability to withstand large enviro
 nmental loads. In most cases\, critical environmental loading arises from 
 the largest waves that hit coastal assets. As such\, an accurate descripti
 on of the characteristics of these largest waves is a top priority for sci
 entists and engineers. This talk will address the statistical description 
 of large storm waves in the coastal zone by analysing extensive datasets o
 f (a) laboratory measurements conducted in the Hydrodynamics laboratory at
  Imperial College London and (b) field measurements from fixed offshore pl
 atforms in the North Sea. In doing so\, the key physical mechanisms that l
 ead to the formation of extreme waves will be identified. Specifically\, n
 ew findings about the competing effects that nonlinear wave-wave interacti
 ons and wave breaking have on the statistical distribution of waves will b
 e presented. These will be used to derive new statistical distributions fo
 r waves that are applicable to a wide range of water depths. Finally\, I w
 ill discuss the implications of using the new\, improved models instead of
  existing models in the engineering design and assessment of offshore and 
 coastal assets.
