One of the causes of the beach erosion is due to the disruption of continuous longshore sand transport by artificial structures. In developing countries including Vietnam with a rapid economic growth, beach erosion that was experienced in Japan in the 1960s‒1970 is now occurring. Various artificial facilities for the economic development have been rapidly constructed on a coast with insufficient adjustment of their plan, and once erosion occurs, the stop-gap measures against erosion have been widely taken, resulting in further downcoast erosion. In this study, these erosion problems were investigated by comparison of aerial photographs together with the field observations on October 23, 2016 and November 9, 2017, taking beach changes in Phan Thiet as an example.
