Shifting Trends of Estate Sand Dunes and Effects on Population Activities in The Cua Dai Area, Quang Nam Province Vietnam

Abstract

The movement of estuarine dunes is a complex process, attracting a lot of attention from scientists. Since its second visible appearance in 2018, many scientists with specialized methods have sought to understand the causes and mechanisms of dune formation in front of Cua Dai. Some studies have shown that the dunes in front of Cua Dai tend to move north and are associated with the dunes on the north bank of Cua Dai. However, these studies only evaluate based on natural laws and ignore the impact of people's development activities. Using general research methods of geographical science, the article has shown the current and future movement trends of dunes in front of Cua Dai: expanding to the west, moving inside Cua Dai, down south, and tending to connect with the sand bar on the southern shore of Cua Dai.
