Dong Nai basin, thereby to control salinity in the raw water pump station in Hoa Phu (belonging to Tan Hiep water plant) and to identify the level of salt reduction at the intake position with water discharge scenarios from Dau Tieng Lake To evaluate changes, the ability to push the salt of Dau Tieng Lake in the case of climate change taking into account sea level rise The results are: Saline control by discharging from Dau Tieng lake to push the salt With climate change scenarios and sea level rise of 0.5 m: It is effective to control saline water at the plant but it is more difficult, time consuming and discharge in comparison to sea level that does not rise With climate change scenarios and sea level rise of 1.0 meter: pushing salt for Tan Hiep water plant will no longer be effective, it is needed to research other solutions to reduce saltwater intrusion like tide sluices T 300.000 m3 T ng công trình , : tốn lan , Hịa Phú , : Telemac 2D Sài Gòn i vi -
