Abstract
Kuala Terengganu is one of the areas which were subjected to critical erosion in Malaysia. It is believed that human activities became one of the causes of this incident. Kuala Terengganu is location of Sultan Mahmud Airport. In January 2008, the Malaysia government approved to upgrade the airport included improvement to the terminal and runway extension. The construction is located near the coast, therefore it is necessary to monitor the coast of Kuala Terengganu. This study focuses on the shoreline change detection along the Kuala Terengganu during ten years period between 2007 until 2017 using LANDSAT Images. Digital Shoreline Analysis System (DSAS) is an extension for the ArcGis was used to identify and measure erosion (shoreline retreat) and accretion (shoreline advance) along the coast. From the analysis, the action will take better information disclosure and state government can take action to reduce the erosion. Environmental impact assessment benefits occur in many guises such as improved project design and improved decision making.
