THE EFFECT OF COASTAL CHANGE BY PABUK STORM SURGE IN SUB-CELL E5-RYG

Abstract

The coastline of Thailand is approximately 3,151 kilometers in length. According to the 2017 Coastal Status Report from Department of Marine and Coastal Resources still has an area of erosion 145.73 kilometers. The problem of coastal erosion requires a clear database of coastal. This research therefore surveyed to create coastline and beach cross section to analyze coastal changes in each season by Real Time Kinematics (RTK) with Global Navigation Satellite System (GNSS). In the case study of Sub-Cell E5-RYG (MAPTAPHUT- MAERUMPUNG, KON AO) then export data to analyze and comparison the coastal change before and after the effect of Pabuk storm surge. From this study found that the coastal accretion 0.005 km² and erosion 0.048 km². The results of the study demonstrate that the area is risk for coastal erosion problems. There should be surveillance and monitoring coastal status in the long term in order to plan and mitigate future disasters.
