Abstract: A circulation model of nutrients has been developed in order to investigate the qualitative changes of water in the flood regulation pond that is newly appeared at Isahaya Bay through constructing the sea dyke. In this model, the mass balances of phosphorus and nitrogen are designed regarding to the interaction between aquatic system and sedimentary system, and temporal changes of pollutant load from rivers are considered. Calculated results show that the phosphorus increases due to the pollutant loads from rivers after the enclosure of the bay, and inorganic one is significantly affected by the advection and the desorption caused by inflow of flood. Concentration of organic phosphorus changes through the biological production.
