Abstract: In this thesis, numerical flow model and warm water transportation model based on triangular mesh and finite volume method are applied to simulate the tidal current field and temperature field, the model can simulate the project region with a good conservation property. After certifying the model with the measured data, the simulated results are in good agreement with the measured data. Through simulating the transportation and diffusion of the thermal water, the spatial and temporal distributions of the thermal water and the temperature process lines of water intake are given. They can provide scientific basis for the design of water intake and outlet, and environmental impact assessment invoked by the warm water.
