Study on Abrasion and Sediment in Angso Duo Island Pariaman City West Sumatera, Indonesia

Rahmat Azizul, Rifardi, Musrifin Galib

Abstract: The purpose of this study was to determine threshold of abrasion rate at coastal area of Angso Duo Island, Pariaman City, West Sumatera, using sediment analysis and image data processing in February 2017. The samples of coastal sediment was collected at four stations in the study area. The change of coastline was observed by using Landsat 5 TM (year 1996 and 2006) and Landsat 8 LDCM (year 2016). The Angso Duo Island is characterized by the fine-grain sediment (sand) and by the high rate of abrasion as shown by the image data interpretation for 20 years (1996-2016 reaches 17 meter which equal to 0.85 meter/year). The major contributing factor for the coastline changes in the study area is due to the wave and the current systems which flow from Indian Ocean through the study area.
