Abstract
Erosion and rising sea level represent important challenges to the Vietnamese society, especially around coastal areas in the middle of the country. A significant length of this coastline has been protected by coastal revetments against natural disasters. Further increases in sea levels will allow higher waves to reach the coastline and thus, will require coastal defenses and breakwaters to be reinforced and strengthened. In this paper, the authors attempt to describe the current erosion situation that has been observed and learned at Cua Dai Beach, which is located in Central Vietnam. The GIS application with satellite images is also used to estimate how coastlines suffer from erosion and other disasters. The effect that future sea level rise might have on coastal structures in Cua Dai Beach is investigated by calculating the expansion in cross section and armor units under several scenarios of sea level rise.
