Abstract

The research grasps water quality contamination source by investigating the data that are superordinate laws and the related plans implemented for establishing water quality improvement measures of upper stream for Chung-Ju Dam, present conditions of the hydraulic and hydrology, the present conditions and plans of environment basic facilities, and present conditions of main contamination source's occurrence load and discharge load, etc. The research used the QUAL2E simulation which is being widely applied to simulation of river water quality because the QUAL2E has high credibility among water quality simulations known throughout the country. On basis of this research, regulations and politic alternatives are required in order to water quality improvement upper stream for the Chung-ju dam, especially establishing processing facilities in the region where loading amount is concentrated should be considered with the additional research regarding cost-efficient facility of pollution source.

본 연구는 충주댐 상류유역의 수질개선대책을 수립하기 위해 실시된 상위 및 관련계획, 수리 수문환경, 환경기초시설 현황 및 계획, 수질현황, 주요 오염원 발생 및 배출현황 등의 자료조사를 통하여 수질오염원을 파악하고 국내에 알려져 있는 수질모델 중 신뢰도가 인정되어 하천수질모의에 널리 적용되고 있는 QUAL2E 모형을 적용하였다. 연구 결과를 토대로 하여 충주댐 상류 유역의 수질개선을 위한 규제와 정책 방안들을 고려한 수질예측이 필요할 것으로 판단되며, 특히 충주댐 상류 유역의 오염원별 수질을 관리하는 방안과 더불어 오염원별 배출부하량이 높은 지역의 대형 환경기초시설에 의한 고도처리시설 도입 및 비점오염 저감시설에 의한 부분을 고려한 추가적인 연구가 필요할 것으로 판단된다.
