In order to improve the river water environment, it is necessary to properly understand the mechanism on water quality changes. Hanzo River is one of tributaries of Honmyo River which is flowing into Isahaya regulation pond. Concentrations of nutrients of Hanzou River are 1.5 to 2 times higher than water at main river. Purification of water quality in this river is important issue for water environmental management. In this study, numerical simulation model composed by two sub-model, basin model and river model, was developed and applied to Hanzo River to predict the water quality changes under wet weather condition in this river.
