Abstract: Every day Vinh Tan thermal power center needs millions of gallons of seawater to cool the machinery system and that volume of seawater will eventually return to the sea. This volume of seawater with a temperature ranging from 32-35 degree celsius pouring into the sea will spread heat to the surrounding environment in a large area, down to the deep layer of the sea. Quantifying the affected space and water temperature, I’m using the ROMS (Regional Ocean Modeling System) model to solve this process. The source of boundary condition data for ROMS is obtained from the databases of NOMADS, COADS, QuikSCAT, TPXO7.1 through OPenDAP data access protocol. Topographic data sources, factory discharge water, river water flow, sea water temperature, discharge water temperature were collected from field measurements. The study area is the coastal sea waters from Hon Dinh headland to Ne headland covered by a network of 80x110 points in the horizontal direction and 5 sigma layers in the vertical direction. The results show that a strip of water with high temperature appears from the outlet of the factory towards the south and parallel to the shoreline. Heat transfer in layers has a similar thing which is very limited to the north because the flow effect from north to south is dominant. A strip of high-temperature water spread to the sea, after 10 days hot water had spread near Ne headland and after 30 days in all three layers, there was a coastal strip of water with a high temperature of over 28°C appearing to spread and stretch. long to the south, in the large surface this strip of water is larger than the middle layer, while the bottom layer is pro
