Abstract The instream flow of the Ara River is to be supplied from the Han River, and so an Environmental Fluid Dynamics Code (EFDC) model was applied to investigate the impact of water-intake to the Ara River on the total river flow and saline water intrusion. Through the numerical simulation of flow and saline water intrusion under different drainage conditions, it was found that the water intake for the Ara River has an impact not only on the hydraulic characteristics (water level and flow rate), but also on the extent of saline water intrusion in the Han River. It was also found that the change of discharge in the Han River, caused by the water supplying to the Ara River, can increase the salt concentration in the vicinity of the Singok Submerged Weir by 0.5 psu. As agricultural productivity can be affected by even this small amount of salt concentration change, much closer attention should be paid to the relation between water-intake condition and its effect on the Han River.
