The occurrences of natural hazard is increasing in frequency and brings with it various impacts on coastal areas, such as coastal erosion along the shoreline of Malaysia. The study of National Coastal Erosion Study (NCES) on 2015 revealed that 8840 km of shoreline in Malaysia with 1,347.6 km were subjected to erosion. The present study selected seven locations in Kuala Terengganu since Terengganu is exposed to the northeast monsoon which could potentially cause coastal erosion. In order to identify the changes in the shoreline of the selected study areas, 2014SPOT-5 and 2016 WorldView-3 images were processed using ArcGIS software to determine the shoreline changes and to categorise the erosion which has occurred. Results show that the erosion in Zone B is more dynamic compared to that in Zone A, as shown by the highest rate8.04% of erosion from Pantai Rhu extending to Pantai Marang. Erosion in Pantai Batu Buruk and Kuala Ibai, respectively with Zone A dominated by the anthropogenic and natural factors, while Zone B dominantly by natural factor only. Therefore, finding an empirical study of analyse the shoreline erosion in Malaysian monsoon environment might provide valuable information for sustainability coastal management.
