N/A This study is to decide water concentration of instream flow to upgrade water quality of Gwangju cheon improving one of instream flow in the upper Gwangju cheon. Present water quality of Gwangju cheon (Based on BOO) maintains 3rd-4th level but this study intends to decide water concentration of instream flow assuming that target water quality is 1st and 2nd level to improve water quality. For QUAL2E applies to estimation form of water quality that is using widely in rivers. And, HEC-RAS form is used to estimate mathematical input value that is using in QUAL2E. In the result of estimation of water quality, it is difficult to upgrade to 1st level because Gwangju cheon is lack of self-purification ability. However, it is possible to improve water quality to 2nd level. According to analyzing of the result of QUAL2E form by 0.5,0.8,1.0 of instream flow, it is decided 0.5㎝s to 2.15㎎/ℓ, 0.8㎝s to 2.70㎎/ℓ, 1.0cms to 2.88㎎/ℓl based on BOO.

광주광역시에서 진행중인 광주천에 대한 자연형 하천정화사업은 다소간 단기적인 방안에 편중되어 있는 것으로 보이며, 그 결과물들이 자연형 하천에 걸맞지 않는 인위적 시설물이 편중되어 있다. 이의 극복을 위해 보다 장기적이며 지속 가능한 대안도 준비되어야 할 것으로 판단된다.

Environmental pollution caused by population increase and industrial development influences river ecosystem. In order to conserve the water quality of the Tamjin river, it is necessary to estimate the BOD reduction rate. The BOD concentration is estimated by QUAL2E model applying in the target year 2007. The study basin of the Tamjin river is divided into 52 elements of 5 reaches. A target reduction rate of the BOD pollutant load which is satisfied mth target water quality in 2007 is predicted. A formula for calculating water quality management using regression analysis based on the various BOD reduction rates of the target basin is suggested.
