In recent years, eutrophication and harmful algal bloom (also known as "red tide") have become major environmental concerns in Bohai Bay. In this paper, a coupled 2D eco-hydrodynamic model has been set up to simulate the dynamics of dissolved inorganic nitrogen (DIN), dissolved inorganic phosphorus (DIP), phytoplankton (PPT) and zooplankton (ZPT) in the red tide monitoring area of Bohai Bay under advection, dispersion and ecological forces. By using the eco-hydrodynamic model, nutrient cycles especially the dynamics of nutrient partitioned in different compartments considered in the model were analyzed based on real world simulations. The contribution of riverine and sediment nutrient load to the eco-dynamics of the system were also analyzed based on scenario model runs. The results showed that the growth of phytoplankton was limited by phosphorus rather than nitrogen which might be an indication of nitrogen pollution. The results also implied the importance of riverine nutrient load to the cycles of nitrogen and the importance of sediment exchange to the cycles of phosphorus and the plankton dynamics. The results revealed several important features of the eco-dynamics of the system.
