ASSESSING THE IMPACTS OF SEA LEVEL RISE ON SAND EXPLOITATION IN THE CAN GIO COASTAL AREA (VIETNAM)

Abstract

In recent years, due to the demand for economic development in Ho Chi Minh as well as the Key Economic Zone of Southern Vietnam, the requirement for construction materials has increased rapidly. There are about 10 sand mines which are reserved and licensed in the Can Gio coastal area. The exploitation of these mines is affecting this area. According to the climate change scenario for 2011 prepared by the Ministry of Natural Resources and Environment (Vietnam) and tidal observation, sea level is rising up in Can Gio area. Sea level rise will enhance the potential of coastal erosion, flooding, saline intrusion and increase fishing activities, as well as other artificial beach projects in the Can Gio area. To assess the impacts of sea level rise and sand exploitation activities in the Can Gio coastal area as well as artificial beaches, this research carries out. Numerical modelling was carried out to assess the effects of sand exploitation coupled with sea level rise on the Can Gio coastal area. The research showed that sand exploitation activities have led to erosion in the study area.
