It rises in Tibet, China, flows through five riparian countries over 4800 km, and draining a catchment area of 795,000 km2 [ MRC, 2005 ], before dividing into several branches in a delta and reaching the East Sea [ Figure 7.1 ].
With its flat and low-elevation delta plain [ Minderhoud et al., 2019 ], Viet Nam’s Mekong Delta (VMD) is highly sensitive to hydrological changes and global sea level rise, and therefore appears to be a “hotspot” of climate change impacts. It covers an area of about 4 million hectares, crossed by a complex network of rivers and canals [ Figure 7.2 ], and is currently home to 17 million inhabitants, i.e. about
