Abstract

Combined sewer solid deposition during dry weather periods and their resuspension during wet weather periods has long been recognized as a major contributor to the first-flush phenomenon. Also, these deposition of sewer solids results in a loss of flow capacity that may restrict flow and cause a local flooding at urban area. In order to solve these problems, measurement of solid deposition for a given sewer system for extended period is needed but this task is very difficult and extremely expensive. This paper presents the development and applicability of estimation equations for solid deposition in sewer systems based on the solid deposition estimated using MOUSE model. As results, the comparison between estimated and measured solid deposition is difficult due to the absent of measured data, but the estimated values using developed equations show applicability compared with the results of MOUSE model and the estimation equations developed by the EPA.

건기에 합류식 관거 내에 퇴적된 고형물은 우기에 재부상하여 초기부하(first-flush) 현상의 주된 원인이 되고 있으며, 이러한 고형물의 퇴적으로 인해 관거 내 통수능이 감소하여 도시지역의 국지적인 내수침수가 발생하고 있다. 이와 같은 문제를 해결하기 위해서는 장기간에 걸친 관거 내 고형물 퇴적량을 관측할 필요가 있으나 많은 비용과 노력이 수반되어야 한다. 본 논문에서는 MOUSE 모형에 의해 산정된 결과로부터 고형물 퇴적량을 산정하기 위한 회귀식의 개발 및 적용성을 검토하였다. 분석 결과 관거 내 퇴적고형물의 관측 자료가 구비되어 있지 않아 실질적으로 비교하기는 곤란하지만 MOUSE 모형이나 EPA(미환경보호청)에서 제시한 공식을 이용하여 산정한 결과와 비교해 볼 때 본 연구에서 개발된 산정식은 적용성이 있음을 보여주고 있다.
