The coastline of Vietnam - annual dynamics derived from 35 years of Earth Observation data

Abstract

Understanding the intricate interplay between alterations in sedimentation patterns and the rising sea levels is of critical significance, particularly for coastal regions at large and, notably, for the vulnerable Mekong Delta. Among the myriad drivers of coastline changes, the repercussions of reservoirs, channel construction, and dredging remain inadequately explored. The construction of reservoirs upstream can drastically alter the sediment flow downstream, reducing the sediment load reaching the delta. Altering natural channels and extensive dredging for navigation and industrial purposes can disrupt sedimentation patterns. Moreover, while the impact of coastal erosion on flooding has been established, it also represents an area of research that remains underexplored. Therefore, the monitoring the coastline of the Mekong Delta is of paramount importance.
