Abstract

This paper sets forth key concepts and advances working definitions for sustainable and resilient infrastructures (S&R-Infra), specifically for water systems. Three water infrastructure scales, such as large, medium, and small scales are considered, each of which is represented by water resource system, regional water and wastewater infrastructure, and local water distribution system, respectively. All three scales are interconnected each other since water travels from sources to end users and returns the other way. This study is beneficial by suggesting indicators to evaluate system sustainability and resilience against outer disturbances. After S&R definitions and potential indicators are provided, application examples are examined to demonstrate the applications of the proposed indicators. Application results show that the proposed indices are useful for quantifying water system performance. While the approach is refined and applied to synthetic cases, it may be considered applicable to real-world systems as system performance indicators and/or system planning and design goals within an optimization framework.

본 연구에서는 예기치 않은 재해에 대비한 물 공급 수자원 시스템의 재해대비성에 대한 지표로서 시스템의 지속가능성(sustainability)과 복원성(resilience)을 (이후, S&R) 산정하는 방안을 제안하였다. 물 공급 시스템을 크게 세 가지 규모(scale)로 구분하였는데, 1) 대규모 시스템은 수계 단위의 수자원 시스템을 의미하며, 2) 중규모 시스템은 권역별 상 하수 및 송 회수 시스템을 나타내고, 마지막으로 3) 소규모 시스템은 지역별 물 배분 시스템을 의미한다. 제안된 정량화 지표를 간단한 수자원 시스템에 적용, 그 활용가능성을 살펴보았으며, 향후 대규모 실제 시스템에 적용하여 재해에 대비한 시스템의 기능 평가/검증 및 설계에 활용이 가능할 것으로 판단된다. 지금까지 개념적으로만 소개되었던 지속가능성과 복원성에 대한 정량화된 지표를 제시함으로써, 기존 물 공급 시스템의 장래 지속가능성 검증, 재해 및 사고에 대한 복원가능성을 판단하는 지표로 활용이 가능하며, 또한 새로 구축하고자 하는 시스템의 계획 및 설계에 있어서는 최적화기법등의 목적함수로 활용이 가능할 것이다.
