남강에 적용된 하천 수질모델의 비교 연구 = Comparison of two water models for the paalication to the Nam river.

다국어 초록 (Multilingual Abstract)

The water quality models were applied to the Nam river The Nam river is one of the major tributaries of the Nakdong river. The entire stretch of 60 ㎞ was divided into 16 reaches. The models were calibrated and verified to the field data. The predicted water qualify showed good agreements with the field measurements by two models. However, the STREAM(Segment Travel River Ecosystem Autograph Model) model was approved to be better· than QUAL 2E model for the Nam river. It may be due to that the dissolved oxygen changes in water bodies are better by STREAM than by QUAL 2E model. From the results, the water quality of the Nam river was affected by the input loadings from the Haman stream. The shortness of the distance from this point to the Nakdong river made the joining water quality to the Nakdong river limit the purification capacity.
