Abstract: A 2D coupled hydrodynamic-biological model which included the effects of tide current, solar radiation, water temperature and inflow nutrients is applied to the simulation of the biological processes on the coastal areas near Tianjin. The hydrodynamic sub-model is 2D model. The biological sub-model described the nitrogen cycles through the food web with four state variables: phytoplankton, zooplankton, pelagic detritus, and inorganic nitrogen. The preparatory assessment of the effect of physical processes on the ecodynamics is analysed. In this paper, the results are described emphasizing the effects of the hydrodynamic constraints on the space-time distribution of the primary and secondary production.
