Abstract

Along with effluence of non-point pollution source, continuous precipitation due to rainy season or localized heavy rain can also be a good reason for increase of flow rate. And if the water level is going up due to the increase, floating debris around rivers and streams will move because of increased flow velocity. However, currently, there are no studies which perform quantitative calculation on movement of floating debris by analyzing amount of rainfall and flow rate in both domestic and abroad. Thus, the present study calculated amount of movement of floating debris based on moving route monitoring results according to changes of effective rainfall and flow rate that are obtained by using SCS-CN method.

장마나 집중호우 등에 의한 지속적인 강우는 비점오염원의 유출과 더불어 유량을 증가시킨다. 그리고 유량의 증가로 수위가 상승하게 되면 하천 주변에 산재되어 있던 부유쓰레기는 빨라진 유속에 의해 이동하게 된다. 하지만 현재 국내외에서 강우량과 유량을 분석하여 부유쓰레기의 이동량을 정량적으로 산출한 연구 사례는 없었다. 이에 본 연구에서는 SCS-CN 방법을 이용하여 산출한 유효 강우량과 유량 변화에 따른 이동 경로 모니터링 결과를 토대로 부유쓰레기의 이동량을 산정하였다.
