A lack of basic information system
Nowadays, the needed information for monitoring, examining, and evaluating the situation of coastal change in Thailand is still insufficient in terms of the continuity of data collection and the up-to-date storage system. The information related to the factors that can cause any coastal change should be available, especially, the wind and wave data. The wind data measured from the inshore station should be calibrated with the wind data from offshore station; then, the determination of wave height, period, and direction can be conducted using the wind data in order to run mathematical modeling for both short- and long-term monitoring of coastal change.
