Building resilience of national infrastructure networks to flood and storm events remains a significant challenge in the UK. In recent years extreme flood and storm events across the UK have affected large numbers of infrastructure networks and their customers, resulting in economic damages and losses of the order of tens of millions of pounds. As extreme flood and storm events become more frequent due to climate change, understanding and modelling the impacts of shocks across multiple infrastructure networks to inform resilience planning is a topic of national importance. Government agencies and infrastructure operators have noted that the lack of coherent datasets of interconnected networks and cross-sectoral resilience metrics makes it challenging to plan for and respond to extreme large-scale weather events.This project aims to address the above challenges by delivering an open-source modelling framework on the DAFNI platform for stress-testing interdependent network resilience against flood and storm events. This framework will be demonstrated through a novel national-scale database of interdependent electricity, transport, water supply, and telecoms networks connected to buildings and population concentrations in the UK. The original research and data collection that created the network risk analysis methodologies was conducted as part of the EPSRC-funded Infrastructure Transitions Research Consortium Programme Grants and with the National Infrastructure Commission. This project will update that analysis and implement it in an accessible, reusable and scalable way on the DAFNI platform. The proposed outcomes of the project will include quantifying the impacts of shocks through damages to infrastructure assets and disruptions to people and the economy dependent on infrastructure services. Further outcomes will include assessing cross-sector resilience options for resisting, absorbing and recovering from shock events, by strengthening infrastructure assets, installing service backups and increasing redundancies across networks. Overall, the project will create novel models, datasets, and tools on infrastructure resilience that will be available to academic, government and industry stakeholders via the DAFNI platform.The project will contribute towards the 'Exploring Resilience Scenarios' theme to enhance the capabilities of the DAFNI Centre of Excellence for Infrastructure Resilience Analysis. Through the DAFNI platform it will: (1) develop collections of models and data; (2) provide tools for exploring and evaluating resilience scenarios across locations and multiple infrastructures; and (3) demonstrate the DAFNI platform to the wider stakeholder community within academia, government and industry.

在英国，国家基础设施网络对洪水和风暴事件的建立弹性仍然是一个重大挑战。近年来，英国的极端洪水和风暴事件影响了大量的基础设施网络及其客户，从而导致经济损失和数千万英镑的损失。由于气候变化，由于极端的洪水和风暴事件变得越来越频繁，因此了解和建模多个基础设施网络的冲击影响弹性计划是一个国家重要性的话题。政府机构和基础架构运营商指出，缺乏相互联系的网络和跨部门弹性指标的一致数据集使计划和应对极端大规模的天气事件的挑战。该项目旨在通过在Dafni平台上为压力范围内的不受压力的互联网互动互动互动互动，以应对上述挑战，以应对上述挑战。该框架将通过一个新型的国家规模数据库，即相互依存的电力，运输，供水和电信网络与英国建筑物和人口集中相关的网络。创建网络风险分析方法的原始研究和数据收集是作为EPSRC资助的基础设施过渡的一部分进行的，研究联盟计划赠款以及国家基础设施委员会。该项目将在DAFNI平台上以可访问，可重复使用和可扩展的方式更新该分析并实施。该项目的拟议结果将包括通过损害基础设施资产的损害以及对人民的中断以及依赖基础设施服务的经济造成的冲击影响。进一步的结果将包括评估跨部门的弹性选择，以抵抗，吸收和从冲击事件中恢复，通过加强基础设施资产，安装服务备份以及在整个网络之间增加冗余。总体而言，该项目将通过DAFNI平台创建有关基础设施弹性的新颖模型，数据集和工具，该项目将为学术，政府和行业利益相关者提供。该项目将有助于“探索弹性情景”主题，以增强DAFNI卓越基础结构弹性能力分析的能力。通过DAFNI平台，它将：（1）开发模型和数据的集合； （2）提供用于探索和评估跨地点和多个基础架构的弹性方案的工具； （3）向学术界，政府和工业范围内的更广泛的利益相关者社区展示了DAFNI平台。
