Abstract
Various environmental issues in this area, including land conversion, uncontrolled mining exploitation in watersheds, damage to coastal ecosystems. There are 11 watersheds and 2 of them are large rivers, namely Batang Anai and Batang Mangau, one of the major rivers is located in Nagari Katapiang. The purpose of this study is to analyze the spatial and temporal dynamics of shoreline changes in Nagari Kataping and the factors that cause line changes. The method used in this study is to analyze changes in the coastline area with overlays on the map and produce a combined map that has an attribute information from each map, analyzing it with Landsat 8 OLI/TIRS Imagery for 2003-2018. The results obtained from the change in the area of the Kataping beach from 1988-2018 reached 58.18 ha. From statistical data processing, the most dominant factor influencing it is the decreasing vegetation on the Kataping coast by 13.56 in 1988-2018. There is an effect of land cover change on the level of shoreline change in the Batang Anai watershed of <50% and the remaining percentage is affected.
