Abstract
Instream flows are defined as the stream flows needed to protect and preserve instream resources and values. They are supplied by the essential discharge for maintaining the channel. However, due to the lack of precipitation during the dry season, which is usually between the months of January and April, natural flows are not enough for the instream flows, thus leaving the dams at a shortage. In this paper, the method which will be discussed will show a physical way to improve water quality by the dilution of water that is supplied from a reservoir or dam, and how it is analyzed at the Han River basin. For the sake of this analysis, the basin has been divided into 33 catchments. Each catchment's natural flow has been simulated by SWAT-K, and the future water demand has been estimated using statistical data. It has also been assumed that the Han River basin has two large reservoirs(Chung-ju dam, and So-yang dam). The supply of potential discharge has been calculated using a case of water separately from each dam, as well as supply water from both dams.
