Analysis of Impact Factors on Wave Deformation in Narrow Channel Seas

In this study, a wave numerical modeling was use to analysis impact factors in the wave transmission and deformation of the incident wave and topographic conditions in a narrow channel sea. Recently, although there have been many studies on the wave modeling, many numerical equations have been limited to the simulation of wave transformation effects. Despite this, the models have been used to design coastal structures in narrow channel sites. This study estimated a wave model (mild slope eq. model) by analyzing the wave energy transmission according to the changing of impact factors (width of channel, bottom slope in channel, incident wave angle, wave period). The results of the numerical experiments showed that the major impact factors influencing wave energy transmission are the width of channel and incident wave direction. Except when the width of channel was larger than 3L (L =Length of wave), the reduction of wave energy was small.
