초록
도심재생하천 내부의 수리적 특성이 열환경 변화에 미치는 영향을 알아보고자 하천의 물리적 구조와 수리적 특성, 기상요소, 온열환경을 분석하였다. 연구 대상지는 복원된 도시하천으로서 큰 의의를 가지는 청계천을 선정하였다. 유형은 물리적 구조별 녹피율의 차이에 따라 유형 I(0.0%)과 유형 II(20.2%)로 구분하였다. 여울이 끝나는 Ba지점에서 수온은
Our goal is to verify how changes in water's hydraulic characteristics after urban regeneration stream can affect any possible transformation of its thermal environment. To that end, we analyzed changes in numerous physical characteristics the subject stream along with the meteorological factors and thermal environment affected by it. Cheonggyecheon was selected as our subject as it is a great example of successful urban regeneration stream. As for physical characteristics, we allocated Type I (0.0%) and Type II (20.2%), depending on the green coverage ratio. As for numerical characteristics, at the point of Ba in which the riffle ends, the water temperature fell by
