Abstract

Coastal erosion is a problem affecting the stability and development of the coastal economic zone in general and the coast of Thua Thien Hue Province in particular. Changes along coastline of Thua Thien Hue have been analyzed using Digital Shoreline Analysis System (DSAS) version 4.3. Multi-temporal satellite images - Landsat is used to analyze coastal variation. This study identifies serious coastal erosion along Thua Thien Hue coastline such as Quang Cong, Quang Ngan (Quang Dien); Hai Duong (Huong Tra); Thuan An town, Phu Thuan (Phu Vang); Vinh Hai and Vinh Hien (Phu Loc) ...; Coastal erosion and sedimentation at Thuan An and Tu Hien inlets threaten natural stability in the Tam Giang - Cau Hai lagoon. The results of the research will help the prevention and mitigation of natural disasters in the coastal area be more effective.
