This project will model the relationships of critical infrastructure in a community, and in particular the cascading effects of loss of key components in the system. The effort will focus on the Hurricane Katrina experience to provide a test bed for the examination of key factors and linkages in the effects of cascading failures as a result of a disaster. The research design will utilize three essential techniques: Key informant interviews, Case study, and Probabilistic modeling. Upon conclusion of the work, the research should provide a clearer understanding of the interrelatedness of key urban infrastructure systems during crisis events.The impact of the research will have a direct effect on three specific areas: 1) creating a better understanding of the interrelated vulnerability of infrastructure systems; 2) creating a more robust picture of the "ripple" effects that occurs in key infrastructure systems; and 3) increasing our ability to model "resiliency" in a community by identifying critical inputs in the development of fragility curves across systems.The results will have implications for hazards mitigation planning and research with respect to natural and technologically-induced disaster events, as well as direct implications for Homeland Security efforts. In both cases, a clearer understanding of the vulnerability and potential resiliency of a community's infrastructure will provide insight into the best allocation of resources to improve capacity and preparedness.

该项目将模拟社区中关键基础设施的关系，特别是系统中关键组件损失的级联效应。这项工作将集中在卡特里娜飓风的经验上，为检查灾难造成的级联失败的影响中的关键因素和联系提供一个试验台。研究设计将利用三种基本技术：关键线人访谈、案例研究和概率建模。在工作结束时，研究应提供对危机事件中关键城市基础设施系统相互关系的更清晰理解。该研究的影响将对三个具体领域产生直接影响：1)更好地了解基础设施系统的相互关联的脆弱性；2)对发生在关键基础设施系统中的“连锁反应”形成更清晰的认识；3)通过识别跨系统脆弱性曲线发展中的关键输入，提高我们在社区中建立“弹性”模型的能力。研究结果将对自然和技术引发的灾害事件的减灾规划和研究产生影响，并对国土安全工作产生直接影响。在这两种情况下，更清楚地了解社区基础设施的脆弱性和潜在弹性，将有助于深入了解如何最佳地分配资源，以提高能力和准备能力。
