Mapping of Coastline Changes in Mangrove Forest using Digital Shoreline Analyst System (DSAS).

Abstract Satellite images have been used for the last 35 years to monitor the erosion rates of the coastline, which has further altered the morphology of the coastline and its biodiversity. In order to make educated judgments about the protection of our coastline biodiversity, shoreline accretion trends over time are crucial for a wide range of coastal challenges and projects. As a result, the goal of this study was to use Landsat 8 OLI to monitor the coastline mangrove forest in Tanjung Piai to distinguish changes in the coastline, as well as to generate land use land cover in 2013 and 2020, detect changes in land use land cover in 2013 until 2020, and identify changes in the coastline mangrove forest in 2013 and 2020. The results showed that the shoreline of Tanjung Piai altered by an average value of accretion per year of 296.14 ha and an average value of reduction per year of 46.87 ha using the End Point Rate (EPR) and Shoreline Change Envelope (SCE) tools from the Digital Shoreline Analyst System (DSAS). The coastal zone must be safeguarded to ensure the safety of those who live close, as well as the ecosystem and habitat’s protection from the effects of rising sea levels.
