Purpose. The study is aimed to analyze the evolution of the coastline of Padang Pariaman Regency, as well as some oceanographic and anthropogenic factors. Methods and Results. In this paper, the results of survey studies are quantified. The coastline evolution is observed using remote sensing techniques on Landsat image data collection and Geographic Information System (GIS) techniques. The coastline evolution is estimated using the overlay method. The evolution of the coastline of Padang Pariaman Regency is due to abrasion along the coast, especially in Katapiang village covering an area of 49.76 ha, where an increase of 27.63 ha from the previous period can be observed. The largest accretion occurred in the village of Malai V Suku with an additional 12.30 ha of land and the Pilubang village with an additional 4.84 ha of land. Such hydro-oceanographic factors as wave speed, high current velocity, and tides affect coastal abrasion in the Padang Pariaman District. Conclusions. The evolution of the coastline is influenced by oceanographic and anthropogenic factors. An oceanographic factor in the form of the highest tide can be observed in Ulakan and Tapakis villages. Anthropogenic factors and the largest land changes can be found in the village of Malai V Suku, amounting to 29.21 ha, and in Katapiang village with an increase of 27.63 ha from the previous period. © W.
