Abstract

The coastal area of Con Dao archipelago in Ba Ria - Vung Tau province is considered having an extremely important location in economic development and the national security. However, the islands locate in a zone where several geological, hydrometeorological and human activities could affect their borders. Coastal hazards such as landslides on islands and erosion at the shorelines are always at high risk. In addition, due to the impact of climate change and sea level rise, the risk of the above hazards will probably occur with increasing frequency and intensity. This research uses a combination of remote sensing image analysis to calculate shoreline evolution over time and a logistic regression model to evaluate the likelihood of the above hazards. The zonation of coastal hazards in the islands shows different erosion - deposition areas and the susceptibility of hazards from high to low. The final risk map provides information about natural hazard conditions for environmental management and protection works, contributing to the socio-economic development of the areas and maritime sovereignty of our nation
