Abstract


This study aims to study wave characteristics and shoreline changes during two seasons in Northeast monsoon (December 2015) and Southwest monsoon (June 2016), at Tumbon Kao Roop Chang, Songkhla Province. The results showed that the monsoonal wind played an important role on wave characteristics and shoreline changes. During Northeast Monsoon, the significant wave height was about 0.61 – 0.89 m (0.79 m in average) and the maximum wave height was 0.66 m with 5.13 – 6.00 seconds in period. While during Southwest Monsoon the significant wave height was about 0.034 – 0.182 m (0.074 m in average) and the maximum wave height was 0.11 m with 3.36 – 5.16 seconds in period. These results demonstrated that both waves were generated by local wind. For the shoreline changes, the Northeast monsoon had a greater impact than Southwest monsoon. During Northeast monsoon, the beaches were essentially erosional. In contrast, the beaches were accretion and also berms feature were found during the southwest monsoon.
