Water Purification Mechanism of Artificial Lagoon in Rinku Park : 3rd Report : Numerical Simulation Using Uchiumi Model

Abstract

The purpose of this study is to clarify the water purification mechanism of artificial lagoon using an ecosystem modelling technique. In the third report, an ecosystem model for an artificial lagoon in Rinku Park was developed with reference to the results of field investigations. The results of the numerical simulation suggested that the nutrient fixing effect of seaweed is large, and water soil qualities significantly depend on the biological parameters about seaweed and sessile animals. Some numerical experiments using the developed ecosystem model were also performed.
