- Abstract
- 논산시의 경우 지리적 특성으로 인해 도심 주변이 점점 광역화 되고 각종 개발이 진행중임에 따라, 본 연구에서는 논산권역 하천의 소유역별 오염물질 발생 및 배출 특성, 지역적 특성 및 유달률 분석에 의한 유역특성 평가를 통해 하천의 효율적인 수질관리 방안을 제시하고자 한다. 행정구역별 오염원관리의 한계를 벗어나기 위하여 강수의 합류지점을 경계로 논산유역 전 수계를 34개의 소유역으로 분류하고, 소유역별 수질오염물질 발생 및 배출부하량 조사를 통해 환경기초시설등을 통한 오염원의 삭감 가능량을 파악하여 소유역별 활용가능한 삭감대책을 제시하였다. 또한, 소유역 말단부 총30개 지점에 대한 수질오염도 측정을 자료를 통해 소유역 하천의 유량 및 수질변화를 조사하고, 소유역별 순유달률 산정과 하천 자정작용에 의한 삭감비율을 비교 분석하여 유달률에 미치는 영향인자인 유하거리, 유량, 유속 등과의 상관관계를 고찰함으로써 하천의 자정기능을 활용한 수질오염물질 저감방법을 모색하고자 했다.
- Alternative Abstract
- This study purposed to present plans for effective management of water quality in rivers through the assessment of basin parameters based on analyses on characteristics of pollutants occurrence and discharge, local characteristics, and runoff ratio by watershed in rivers in the region of Nonsan. Based on the boundary of the junction of rivers, the whole water systems in the region of Nonsan were divided into 34 watersheds, and an examination was made on pollutants occurrence and discharge load by watershed. Through this examination, the possible amount of reducing pollutants by environmental facilities and measures to reduce them were presented. In addition, pollution of water quality on 30 spots in total on the terminal part of watershed was measured, and flux and changes in water quality of watersheds were investigated. A net runoff ratio by watersheds was calculated and the net runoff ratio and a reduction ratio by self-purification of water were compared and analyzed. By considering correlation between flow distance, flux, and the drift of a current, which are influential factors on the runoff ratio, this study purposed to grope for methods of reducing pollutants using self-purification function of rivers.
