ABSTRACT:
Cua Dai is one of the 21 estuaries in the Central region and is the first river mouth to the north of the South Central Coastal region. It is renowned for its beautiful beaches, which attract many tourists. Additionally, the Cua Dai River mouth area is a fishing ground for local fishermen due to its rich marine biodiversity. However, a serious issue has emerged in this area. Cua Dai Beach has been facing severe erosion for several years, threatening its natural beauty. This article employs an integrated geographical approach, utilizing two main methods: document collection (research on geology and hydrodynamics) to determine historical changes and on-site surveys (in point format) to assess the extent and current status of erosion. Information exchange with residents is also conducted to understand the situation and gather data identifying the causes of erosion and sedimentation in the Cua Dai area, part of the lower Thu Bon River system in south-central Vietnam. The results indicate that erosion and sedimentation in the research area are influenced by both natural and anthropogenic factors, with no single factor prevailing.
KEYWORDS:erosion, sedimentation, Cua Dai, Vietnam.
