Environmental Simulation of Osaka Bay-Ecosystem Model including Land Load

Abstract

In order to evaluate the environmental influence around coastal area, it is very important to develop the mathematical model for the environmental simulation. In the present paper, the ecosystem model in Yura area is developed with influence of river and underground water from woods and residential wastewater. The results of numerical simulation suggests that the load from woods affects very strong quickly to nutrium but not so strong to phytoplankton. It can not be ignored to increase production of the wastewater.
