未来洪水风险的一系列解决方案可供选择，从通常纳入可持续排水系统（SuDS）的蓝绿基础设施（BGI）到传统的灰色基础设施（例如管网，储罐，防洪墙）。每一种方法在成本、实施灵活性和提供防洪功能以外的一系列更广泛效益的能力方面都有不同的特点。在考虑这些方法时必须解决的一个重要问题是，在任何地点和任何未来时间，什么是最合适的灰色和蓝绿色解决方案组合？本文采用适应路径的方法来比较一系列的替代方案，以处理当前和预期的未来洪水风险的一部分，伦敦自治市。单独考虑和结合考虑的解决方案包括灰管扩张、生物滞留细胞、可渗透路面和储存池。一个方法框架将一系列现有工具结合起来，用于制定、评估和描述每一条路径，包括一个雨水管理模型、一个南方发展机会选择工具、一个适应路径生成器和CIRIA B£ST工具，用于将多种效益货币化。气候变化是由英国水工业研究方法为代表，建立未来的降雨强度下水道和BGI设计。结果表明，通过更广泛地考虑多种效益，扩大对适应途径进行比较和评估的方式，在推迟干预措施直到需要缓解洪水风险与提供与干预措施相关的多种效益之间存在权衡，以便在引入新的备选方案之前不需要达到绩效阈值。每一备选办法的资本费用和业务及维护费用的相对比例对该备选办法何时执行以及执行率都有影响。与每种途径相关的多种利益的货币化表明，它们的经济共同评价以及基础设施成本可以改变对一种途径的偏好。本文是“城市防洪”专题的一部分。
A range of solutions to future flood risk are available ranging from blue-green infrastructure (BGI) as commonly incorporated in sustainable drainage systems (SuDS) to traditional grey infrastructure (e.g. pipe networks, storage tanks, flood walls). Each offers a different profile with respect to costs, flexibility of implementation and the ability to deliver a range of wider benefits beyond their flood protection function. An important question that must be addressed when considering these approaches is what is the most suitable mix of grey and blue-green solutions to urban flooding at any location and at any future time? This paper uses an adaptation pathways approach to compare a range of alternative options to deal with current and expected future flood risk in part of a London borough. Solutions considered separately and in combination include grey pipe expansion, bioretention cells, permeable pavements and storage ponds. A methodological framework combines a range of existing tools to develop, assess and characterize each pathway, including a storm water management model (SWMM), a SuDs opportunity selection tool, an adaptation pathway generator and the CIRIA B£ST tool for monetizing multiple benefits. Climate change is represented by the UK Water Industry Research method for establishing future rainfall intensities for sewer and BGI design. The results showed that by extending the way in which adaptation pathways are compared and evaluated through the wider consideration of multiple benefits there is a trade-off between deferring interventions until they are needed for flood risk mitigation and delivering the multiple benefits associated with interventions so that performance thresholds do not need to be met before introducing new options. The relative contribution of each option's capital and operation and maintenance costs has implications on when the option is implemented as well as the rate of implementation. The monetization of the multiple benefits associated with each pathway shows that their economic co-evaluation alongside infrastructure costs can change the preference for one pathway over another. This article is part of the theme issue ‘Urban flood resilience’.
