Abstract

On average, five to six typhoons hit the Vietnamese coastline every year, often causing great destruction and many deaths as they move in over land. When a typhoon passes it brings high water levels, large waves, strong winds, and heavy rainfall. The high water levels, in combination with large waves, may induce overtopping and erosion of dikes and sand dunes. This can lead to flooding and saltwater intrusion to farmland, with water masses destroying crops, and in extreme cases can result in the loss of life and property. The main objectives of the present study were to quantify the impact of typhoons on the Vietnamese coastline with respect to overtopping and erosion, and to assess future effects for people living in these areas, especially in view of climate change. The study of the consequences of typhoon attacks was limited to two different but representative areas along the Vietnamese coastline: Hai Hau Beach in Nam Dinh Province and Ly Hoa Beach in Quang Binh Province. The former study area includes man-made dikes and the latter one natural sand dunes.
