Abstract

Prediction of particle kinematics in extreme wave events generated by focusing is still difficult. The semi-theoretical method of Grue et al (2004) over-predicts velocities below MWL in extreme cases and a purely theoretical method is still lacking. Thus a theoretical method is presented based on higher order terms and a simplistic wave-wave interaction. Results of the new method are compared with those of Baldock et al(1996) and by extension, those of Grue et al(2004) whose results corroborate those of Baldock et al(1996). The comparison shows a surprisingly good agreement with measurements and very significant improvement over existing methods.
