남강댐 하류하천의 오염원별 기여도 및 낙동강 본류의 수질 영향 평가

Abstract

The Nam River basin is divided into the Nam river dam rage sphere and the Nam River rage sphere. The Nam River rage sphere`s length is 77.6 km from the dam of the Nam river. And many cities (Jinju, Haman, Uiryeong, Goseong-gun, etc.) and Jinju-Changping industrial complex is located in the rage sphere, so there is the high probability that contamination occurs. Nevertheless it also has a key point of the solution of the water supply in Western Gyeongnam there are few of the studies of the Nam River in term of the watershed management. This study estimates the pollutant load per the pollution source in the downstream watershed of the dam of the Nam River, and investigates and analyzes the point/non-point sources and the characteristics of the tributaries center. This research also estimates the effect of the water pollution in the dam of the Nam River to the main stream of the Nakdong River and to achieve a water quality improvement. Futhermore, the correlation analysis and exploratory factor analysis between the parameters are performed to identify the contamination contribution of the major turbidities in the Nam River watershed. This study is expected to present a customized plan to manage the Nam River Basin in the future through integrated watershed management techniques.
