Researches on combinion of hydrological and hydrodynamic models are very important when performing risk assessment and disaster management, including saline intrusion, which is especially important for watersheds, with limited measurement data. The objective of this study is linking two types of hydrological and hydrodynamic models to simulate the scope of salinity intrusion in the Ve estuary, Quang Ngai province. Firstly, SWAT/NAM is applied to calculate flow rate, and then MIKE 21/3 model is applied for hydraulic and salt intrusion simulation. The calibration and validation are also done to show that the acceptable reliability of simulation. Simulation result showed that salinity intrusion depends on water discharge, water level, tidal regime according to dry and wet seasons; the longest distance of saline intrusion from the rivermouth is 5.47 km, occurring in the dry season.
