| Zusammenfassung |
| The present paper investigated the extent of the flood propagation in the
Vietnamese Mekong Delta under different projected flood hydrographs,
considering the 2000 flood event (the 20-yr return period event, T. V. H. Le et
al., 2007) as the basis for computation. The analysis herein was done to
demonstrate the particular 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, the first one in a scenario of climate
change without considering developments in the Mekong Basin,and the
second one in a scenario of climate change taking into account future
development of the delta. Analyses were done to identify the areas sensitive
to floods, considering the uncertainty of the projection of both the upstream
and downstream boundary conditions. In addition, due to the rice-dominated
culture in the Vietnamese Mekong Delta, possible impacts of floods on the
rice-based farming systems were also analysed. |
