umerical Study of Regular and Irregular Wave Overtopping Including the Effect of Sea Level Rise

摘要

Wave overtopping is one of the most important processes for the designof seawalls. During the past few decades methods for predicting waveovertopping of coastal structures have continuously been developed. Inthis study, a numerical wave flume based on two-dimensionalReynolds-averaged Navier-Stokes equations with a VOF (Volume OfFluid) method (Hirt and Nichols, 1981) is described. We are concernedwith increasing wave overtopping volume by the sea level rise due toglobal warming, and numerical simulations are carried out to estimatewave overtopping quantity using the two-dimensional numerical waveflume under regular and irregular wave conditions. The influence ofhow the water level, wave height and wave period affect theovertopping quantity has been investigated.
