Description
Summary:This study was conducted to observe the dynamic of shoreline changes in Sangsit Region, Bali Province using multi-temporal remote sensing datasets. The remote sensing data were acquired from several Landsat images in the period of 2000-2019 (20 years) with 30-meter spatial resolution. Digital Shoreline Analysis System (DSAS) method was used to analyse data images to determine the shoreline changes. Prior to the analysis, the images were corrected by ground check data. It revealed that the shoreline changes has occur in Sangsit Region for period of 20 years (2000-2019). The results obtained indicate that there is a change in shoreline with mild accretion to less extreme abrasion categories which occurred in the Sangsit Region in that period. From 2000-2005 it shows an accretion of 221.03 m which is categorized as mild accretion and from 2005-2019 the shoreline changes that occur is only an abrasion its categorized as mild to less extreme abrasion. The highest abrasion occurred in the period of 2010-2015 which the abrasion is around 49.65 m.
