In the reservoir of Shimaji Gawa Dam, heavy metals, such as iron and manganese, liquate from the bottom because of anoxic water. To improve the water quality the equipment to supply the high oxygen concentration water was introduced in the reservoir. To make a high accurate numerical model to simulate the behavior of iron and manganese the time lag between the oxidation of dissolved iron and dissolved manganese and the oxygen supplement have to be modeled.
In this study, we propose the vertical one dimensional water quality model considering the time lag of the oxidation for iron and manganese. We found that the time rag can be fairly modeled by using ORP as a parameter for the oxidation.
