Abstrakt: The Panare River mouth in Pattani Province has become a serious issue. Longshore sediments are blocking the entrance, despite jetties designed to trap sediments and sand bypassing to open the river mouth. However, these measures were unable to effectively solve the problem, as local fishers struggled to navigate their boats through the waterway with ease. Therefore, to discuss this issue, it is necessary to study the shoreline change in this area, determine the net shoreline movement and endpoint rate of shoreline position, and analyze the relationship of sand bypassing over various periods. There needs to be analyzed by using the Digital Shoreline Analysis System (DSAS) tool within a Geographic Information System to identify the shoreline from satellite images from the years 2007, 2011, 2015, 2016, and 2020, with the shoreline adjusted to reference the mean sea level. The study found that the western side experiences a maximum accumulation rate of 17.19 meters per year and a maximum erosion rate. [ABSTRACT FROM AUTHOR]
