| Abstract: | An ecosystem-based water quality model was designed to estimate the biochemical reaction of nutrient and dissolved oxygen in conjunction with a three-dimensional hydrodynamic and sediment model. As both phosphorus and nitrogen successively limit phytoplankton growth in many estuaries, the model simulates both there nutrient cycles each using five variables, namely, dissolved inorganic nutri- ent, detritic organic matter, benthic matter, phytoplankton and zooplankton. |
