This paper investigated the extent of the flood propagation in the Vietnamese Mekong Delta under different projected flood hydrographs, considering the 2000 flood event as the basis for computation. The research was conducted to demonstrate the complexity of the flood dynamics, which was simulated by the 1-D modelling system ISIS used by the Mekong River Commission. The floods of the year 2050 are simulated using a projected sea level rise of +30 cm. The future flood hydrograph changes at Kratie, Cambodia, were also applied for the upstream boundary condition by using an adjusted regional climate model. Two future flood hydrographs were applied at the upstream part of the delta. Analyses identified the areas sensitive to floods, considering the uncertainty of the projection of both the upstream and downstream boundary conditions. Possible impacts of floods on the rice-based farming systems were also analysed.
