In recent years, i.e., in 2016 and 2020, large-scale saltwater intrusion has been causing shortage of freshwater for domestic and agricultural uses in the Vietnamese Mekong Delta. Therefore, sufficient understanding of the impact factors on saltwater intrusion in the delta is important for water resources management. This paper examines the effects of reduced water flow by upstream dams’ operation and river bed incision on saltwater intrusion in the Mekong Delta. In that regard, long-term water flow at two upstream hydrology stations from 1980 to 2020 and river bed incision from 2009 to 2017 were analyzed. Then, one-dimensional hydrodynamic and advection-dispersion model was used to c...
