OPTIMUM FREQUENCY DISCRETIZATION AND ITS IMPLICATIONS ON EXTREME INFRA-GRAVITY WAVE RUNUP

Abstract

Throughout history “sneaker” waves or “king” waves (in Australia), also referred in this study as extreme infragravity (EIG) waves, have been responsible for killing several people throughout the world. Particularly on the coast of Oregon, more than 21 people have died since the year 1990 due to this phenomenon (http://www.oregonlive.com). People that are usually walking by the beach on a “nice” day are suddenly surprised and washed away by what appears to be a “tsunami-like” wave which in reality is an EIG wave.
