Abstract

Abstract

A dramatic increase in the sea reclamation works around the Bohai bay since 2000 has resulted in a change in the tidal field near the engineering area, which influenced both the spatial and temporal distribution of the high temperature concentrated salt water discharged in the sea. A three-dimensional mathematical model based on the different shoreline and topographic conditions in 2000 and 2015 was established to stimulate the high temperature concentrated salt water discharged in the sea by three power plants along the Bohai Bay. The results of stimulations show that great changes have taken place in the characteristics of both the tidal filed and the transport and diffusion of high temperature concentrated water in the Bohai Bay during the last ten years. With the completion of the project, the average salinity of the Bohai Bay increased by 0.203 and the average temperature increased by 0.105℃, in the meanwhile both the transport and diffusion rate of high concentrated salt water in the sea area near the Caofeidian increased significantly. Given the condition the flow of the drain increased to 12.7 m³/s, the highest temperature in the bay reached 26.46℃, which is 2.72℃ higher than that in 2015. This model can accurately simulate and predict the salinity and temperature distribution of the effluent and provide the theoretical basis for the locations of outlets of the power plants.
