Shoreline Change Detection Using Dsas in Pariaman City, West Sumatera

Abstract

This study was conducted to determine the shoreline change that occurred in the coastal of Pariaman city due to accretion and erosion. The present study of the shoreline changes along Pariaman City was done using DSAS 5.0 vector analysis. Landsat 5 TM 1989, Landsat 7 ETM+1999 and 2011, and Landsat 8 OLI/TIRS 2020 images were interpreted first. The results indicate that during 1989 – 1999 there was abrasion with an average distance of change of 281,60 m. The period from 1999 to 2011 was characterized by accretion with an average distance of change of 15,98 m. The latter period 2011 – 2020 was dominated by accretion with an average distance of change of 53,68 m. The indicated fundamental output of the study is to provide useful scientific information and data for development planning and coastal areas, especially those managing the environment and their ecosystems, as well as for the government and related stakeholders and academics and scientists for the use of resources and space in coastal areas. Stakeholders include the city government office in Padang Pariaman, Ministry of Marine Affairs and Fisheries, Regional Disaster Management Agency and Ministry of Public Works and Public Housing of Republic of Indonesia.
