An estuary is very important that the seawater and the freshwater meet and they formed wide foreshore and estuarine which is used as the habitat of various living thing and spawning bed of fish. Masan bay is typical closing bay in Korea. It is located 9 km from the open sea and most inside of Jinhae bay. The width of bay entrance is less than 1 km, where the flow velocity is very low. The large scale industrial complex of Masan bay is located in near Masan and Changwon city whose population is about 100 million. Because of low tidal velocity, the pollutants from the land are accumulated, which makes the water quality worse in Masan bay. The purpose of this study is to analyze the various hydraulic characteristics using RMA-2 model. The advection and diffusion of pollutant is also simulated using RMA-4 model according to the inflow of Changwon-stream and Nam-stream. The hydraulic simulations include the effect of tide which can be characterized by the tide data of Masan bay tide observatory.
