APPLICABILITY OF A SINGLE-COMPONENT WAVE APPROXIMATION FOR ESTIMATING VERTICAL DISTRIBUTION OF HORIZONTAL VELOCITIES

Abstract

 In the official explanation of technological standards for offshore wind power facilities in Japan, it is mentioned that the numerical wave tank “CADMAS-SURF” is one of the method for generating time series profiles of nonlinear irregular wave and its computing loads can be reduced by using a coupling method, which is proposed by Hirayama and Nakamura (2015), with one of the Boussinesq-type wave equation model “NOWT-PARI”. In this study, the coupling method named “Single component wave approximation” is modified and its applicability to calculation of wave shoaling on slopping bathymetry is discussed.
