Abstract

Waves are the main factor inducing coastal erosion. The main objectives of this study are to investigate coastal
erosion by using artificial winds which blow from the east. The wind speed increased from ascending starting from 5
m/s to 20 m/s. Wave spectrum is used for this purpose. Wave spectrum output was taken by different wind speeds.
The wave spectra refraction patterns are modeled from WAM-cycle4 model. The simulations of model were used
to model the wave spectrum along the shoreline. The results show that the wave spectra extracted from ocean
wave model which resolution is 0.017×0.017 degree latitude/longitude grid over the area of interest. The area that
we study is an embayment shoreline which the wave energy is dispersed along the lines of equivalent depth. That
means the coastal erosion in this area does not have much effect by the wave spectrum. Using WAM-cycle4 model
shows that there is no significant difference of the wave spectrum at the shoreline before and after adding the
constructions into grid experiment on domain of ocean wave model, so the constructions in distance of 20 km, from
shoreline of Songkhla should not cause more erosion to shoreline.
