Abstract

Increase of delivery effect of pollutant loads and surface runoff due to urbanization of catchment area results in serious environmental problems in receiving urban streams. This study aims to develop integrated stormwater management system to assist efficient urban stream flow and water quality control using information from the Storm Water Management Model (SWMM), real time water level and quality monitoring system and remote or automatic treatment facility control system. Based on field observations in the study site, most of the pollutant loads are flushed within 4 hours of the rainfall event. SWMM simulation results indicates that the treatment system can store up to 6 mm of cumulative rainfall in the study catchment area, and this means any type of normal rainfall situation can be treated using the system. Relationship between rainfall amount and fill time were developed for various rainfall duration for operation of stormwater treatment system in this study. This study can further provide inputs of river water quality model and thus can effectively assist integrated water resources management in urban catchment and streams.

도시지역의 소하천은 불투수 면적의 증가 및 우수관거의 발달로 인해 유역의 오염물질 및 강우 유출수의 유달률이 증가한 반면 비강우시에 현저하게 유량이 감소되어 하천환경에 심각한 문제를 나타내고 있다. 본 연구에서는 도시 하천의 유량과 수질 문제를 저감하기 위해 개발된 초기강우 저류 및 처리시설을 효율적으로 운영하기 위해 SWMM 도시유역모델 적용 결과와 자동모니터링 시스템을 이용하는 종합관리시스템을 개발하였다. 본 연구의 대상 지역인 관평천 유역의 대부분의 강우사상에서 오염물질은 초기 4시간의 강우 유출수에 집중되어 있는 것으로 관찰되었으며 이는 처리시설의 용량 결정에 있어 가장 중요한 인자로 작용한다. 본 시험 유역에서 유역모델인 SWMM을 이용하여 계산한 결과 처리시설에서 수용할 수 있는 초기우수 유출량은 약 6 mm의 누적강우량으로 산정되었으며 이는 대상지역에서 발생하는 대부분의 소규모 강우에 대해 처리가 가능하다는 것을 의미한다. 본 연구 결과는 강우-유출 모델과 연계한 초기우수 처리시설 운영을 위한 가이드라인을 제시하고 있으며, 하천 수질 모델과 연결할 경우 유입하천에 미치는 영향을 사전에 예측할 수 있으며, 유역의 조건과 연계하여 도시하천의 유역연계 종합 수질관리를 위한 중요한 자료를 제공할 수 있을 것이다.
