Data underlying a conceptual framework for the analysis of engineering and socio-ecological resilience of urban drainage systems

Although resilience contributes to improving the sustainability of urban drainage systems (UDSs), in general, it is not considered in UDS management; furthermore, when it is considered, usually it is considered either as engineering (ER) or as socio-ecological (SER) resilience. This article proposes and discusses a conceptual framework that can analyse ER and SER through a comprehensive resilience (CR) index in a UDS with a focus on floods, considering national and international experiences and methodologies related to resilience analyses and is applicable to UDSs. The framework was evaluated in the Southern Drainage System (SDS) of the city of Cali, Colombia, obtaining moderate values of ER and the CR index, and low values of SER. This conceptual framework can be useful for decision-makers in UDSs management and should be evaluated considering different threat scenarios and mitigation strategies.

尽管韧性有助于提升城市排水系统（Urban Drainage Systems, UDSs）的可持续性，但当前城市排水系统的管理工作普遍未纳入韧性考量；即便纳入韧性考量，通常也仅将其划分为工程韧性（Engineering Resilience, ER）或社会生态韧性（Socio-ecological Resilience, SER）两类。本文提出并论述了一套概念框架，该框架可依托综合韧性（Comprehensive Resilience, CR）指数，针对聚焦洪涝场景的城市排水系统开展工程韧性与社会生态韧性分析；框架整合了国内外韧性分析相关经验与方法体系，且可推广应用于各类城市排水系统。该框架已在哥伦比亚卡利市南部排水系统（Southern Drainage System, SDS）中完成实证验证，结果显示工程韧性与综合韧性指数得分处于中等水平，社会生态韧性得分偏低。这套概念框架可为城市排水系统的管理决策者提供有效决策支撑，后续可结合不同威胁场景与减灾策略开展进一步验证评估。
