The thermal discharge from the Houshi power plant in China has been increased continuously with the increase in power supply. In order to understand the waste heat pollution conditions in the coastal areas of the Houshi power plant, we proposed a modified Princeton Ocean Model (POM) model to conduct three-dimensional numerical simulations for heat transport in the coastal areas of the plant. The proposed model has been verified to be valid in our previous study. This study employed the verified model to predict heat transport under the future operational conditions of the power plant with a thermal discharge of Q s=217.0m3/s. The prediction results indicate that a larger area of waters near the plant outfall will have a temperature rise larger than 4 °C, and this area of temperature rise is close to the water intake of the power plant. Besides, the heat accumulation phenomena will be serious in the depth direction and this will bring great influence to marine ecological environment, especially to benthic organisms. It is suggested that some measures are necessary to reduce temperature rise in the coastal areas of the Houshi power plant in the future. ? (2013) Trans Tech Publications, Switzerland.
