Detection of shoreline changes: a geospatial data analysis in Vung Tau City, Southern Vietnam

Abstract

In recent years, beach and shoreline erosion has occurred increasingly around the world. Because of climate change and human activities, many beaches and shorelines have been eroded severely in Vietnam, especially in Vung Tau City. In order to understand and explain the reasons why Vung Tau beaches have been eroded, the author applied the Geographic Information System (GIS) and Remote Sensing (RS) to analyze the movement of beach in the past and present. The results showed that Vung Tau city has witnessed a massive shoreline replacement including severe erosion and gradual accretionsince 1989. CuaLap river mouth features all-time biggest changes with more than 800 meter of retreating shoreline.
