Sediment Problem Related to the Expansion Project of Tianwan Nuclear Power Plant

The sediment problem related to the expansion project of Tianwan Nuclear Power Plant was studied. Firstly, the hydrology and sediment environments in the ocean area near the project are analyzed. Secondly, the equations and difference method of mathematical model are introduced. Thirdly, based on the observed data in 2010, two-dimensional model of wave, tidal current and sediment transport is used to study the tidal field and Terrain erosion and deposion field. The results show that, it is feasible to implement the expansion from the view of tidal current and sediment.
