管理当前和未来的城市洪水风险必须考虑现有（和新的）基础设施系统之间的连接（即互操作性），以管理雨水（洪积洪水）。然而，由于缺乏系统的办法来确定可互操作的洪水管理干预措施，错过了将现有基础设施（如排水、道路、土地使用和建筑物）投资与蓝绿色基础设施（如可持续城市排水系统、绿色屋顶、绿色空间）结合起来的联合收割机投资机会。在这项研究中，提出了一个空间分析框架相结合的水动力学模型与基础设施系统的空间信息，为系统级的城市洪水管理（UFM）提供战略方向。该框架以三类数据为基础：（一）洪水危险区（即确定洪水问题的空间特征）;（二）洪水来源区（即造成地表洪水最多的地区）;（三）不同系统的互操作潜力（即哪些基础设施系统可有助于水管理功能）。应用于纽卡斯尔泰恩河（英国）的城市集水区，该研究说明了新奇的空间数据源相结合，以系统的方式，并强调了空间（不）连接方面的洪水源区（其中大部分的洪水管理干预是必需的）和受益地区（其中大部分减少洪水发生）。该框架从可互操作的角度提供了一个管理雨水路径的战略工具，可以帮助考虑跨多个系统的UFM的城市规模基础设施开发。本文是主题问题“城市洪水防御”的一部分。
Managing current and future urban flood risks must consider the connection (i.e. interoperability) between existing (and new) infrastructure systems to manage stormwater (pluvial flooding). Yet, due to a lack of systematic approaches to identify interoperable flood management interventions, opportunities are missed to combine investments of existing infrastructure (e.g. drainage, roads, land use and buildings) with blue-green infrastructure (e.g. sustainable urban drainage systems, green roofs, green spaces). In this study, a spatial analysis framework is presented combining hydrodynamic modelling with spatial information on infrastructure systems to provide strategic direction for systems-level urban flood management (UFM). The framework is built upon three categories of data: (i) flood hazard areas (i.e. characterize the spatial flood problem); (ii) flood source areas (i.e. areas contributing the most to surface flooding); (iii) the interoperable potential of different systems (i.e. which infrastructure systems can contribute to water management functions). Applied to the urban catchment of Newcastle-Upon-Tyne (UK), the study illustrates the novelty of combining spatial data sources in a systematic way, and highlights the spatial (dis)connectivity in terms of flood source areas (where most of the flood management intervention is required) and the benefit areas (where most of the reduction in flooding occurs). The framework provides a strategic tool for managing stormwater pathways from an interoperable perspective that can help city-scale infrastructure development that considers UFM across multiple systems.This article is part of the theme issue ‘Urban flood resilience’.
