Numerical Simulation of 2-D Model of Cooling Water Draining into the Bay with Waves and Tidal Currents

With the development of economy in coastal zones in China, the energy requirement is increasing greatly. Many large power plants have been built near bays in China recently, and function of power plant need drain large warm water into bays, which will change current field near outfall and have effect on seawater temperature going up in the bay. In this study, the combined actions of waves and tidal currents in estuarine and coastal areas are considered and a 2-d hydrodynamics and temperature transport model by waves and tidal currents has been established, in which. The wind action and the effect of radiation stress of waves on current and temperature transport are taken into account. It can simulate the distribution condition in current field and temperature field of cooling water correctly and provide credible technical data for ocean environmental impact assessment.
