Current Situation and Tendency of Coastal Change in Quangnam Province Under Impacts of Sea Level Rise

The coastal area located in Quangnam Province has been mainly formed by sandy sediments that are easily changed under the impacts of natural factors and human activities. The use of Landsat satellite images associated with the GIS manipulations will result in reliable identification for the trend of coastal changes. The results showed that the erosion and accretion were occurring in the period from 1990 – 2011. However, the erosion has dominated in many areas, particularly in Cua Dai Estuary and An Hoa Pool, which has had complicated tendencies of coastal change with erosion rates of 31.1 m/year and 7.3 m/year, respectively. The application of the Bruun Model indicated that Cua Dai Estuary and An Hoa Pool underwent the highest erosion levels by adopting the low and high scenarios suggested by Vietnamese Ministry of Natural Resources and Environment in 2100, with specific sea rise levels of 3 m and 5 m, respectively
