An evaluation of the depth of similarity between linear and non-linear wave theories

An evaluation of the wave behavior and the effects of kinematics and dynamic properties of wave particles on the submerged members of a jacket platform have been accomplished. The Stokes fifthorder and Airy wave theories have been employed to evaluate the kinematics and dynamic properties of wave particles. SAP2000 software was used to determine and evaluate the wave properties. The aim of this study is to model both theories and determining a depth of water, in which both theories indicate the same behavior. The study has found that the non-linear fifth-order theory shows similar behavior with the linear Airy wave theory from 10 meters below the SWL toward the sea floor with 99% of similarity.
