Determination of Coastline Changes by Using Geospatial Technology Along the Pantai Kuala Nerus, Terengganu

Abstract

Abstract The phenomenon of coastal erosion is a natural disaster that often occurs every year on the East Coast of Peninsular Malaysia. Coastal erosion can be identified through changes in coastlines found in coastal areas. Beaches in the state of Terengganu often face the problem of big waves and strong winds during the monsoon season. Coastal erosion can be identified through changes in coastlines found in coastal areas. The Ruin Monsoon phenomenon which causes tides and violent waves as high as almost four meters has eroded the land little by little over the past few decades. This study aims to determine the coastline change from 2016 until 2020 by using geospatial technology at Pantai Kuala Nerus, Terengganu. Furthermore, this study has three objectives to achieve. The first objective is to identify the coastline by using multispectral satellite imagery. The second objective is to analyze the rate of erosion and accretion along Pantai Kuala Nerus. The third objective is to determine the category of Pantai Kuala Nerus coastline according to the Malaysia National Coast Erosion Study (NCES) guidelines. The study concludes almost all erosion area in Pantai Kuala Nerus is included in critical and high erosion rate.
