Popis: Climate change poses a critical risk to the sustainable development of many regions in Vietnam, especially inthe Mekong River. In this paper, we show the specific extreme value distributions of rainfall, flow, and crest ofsalinity based on the hydrological data from 1975 to 2017 in An Giang and Ca Mau provinces in the MekongDelta. We also derive a theoretical model and validate its accuracy compared to the empirical data over theyears. The results demonstrate that the extremely high flows increase in both magnitude and frequency, whilethe extremely low ones are projected to occur less often under the climate change. The results can further help the local governments reduce the risk of lack water in dry season, control the salinization, and avoid the threat of flooding in the downstream of the Mekong Delta.
