Abstract

In recent years, due to the impact of climate change and sea level rise, saline intrusion in Ho Chi Minh City has been acrimonious and tends to become more and more unusual, especially due to the influence of the El-NiNo phenomenon, the rainy season comes late but ends early with the total rainfall in 2015 and 2019 is very low, so salinity intrudes very deeply into the interior fields with very high salinity, causing a lot of damage for socio-economic.

Although the city government has built many irrigation systems and deployed many solutions to cope with saline intrusion, but still have not met the requirements due to unsynchronized measurement and calculation of salinity forecast and there are still many shortcomings, so in this paper presenting the assessment of the impacts of climate change, and sea level rise on the Dong Nai-SaiGon river system and propose a more effective response to the damage caused by saline intrusion
