UNCERTAINTIES IN PREDICTION OF WAVE KINEMATICS IN IRREGULAR WAVES

Irregular water wave kinematics have recently been measured in the wave flume at Norwegian Hydrodynamics Laboratories (NHL) in Trondheim, using Laser Doppler Velocimetry (LDV) equipment (Skjelbreia et al., 1989 and 1991). The use of Wheeler stretching theory to estimate water wave kinematics in irregular waves is recommended to represent the best fit to the measurements. Reviewing available literature on water wave kinematics, Gudmestad (1992) arrives at the same conclusion.
