HSD-SGER: Understanding Critical Infrastructure in Crisis: Impacts, Linkages and Resiliency in Hurricane Katrina

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丢失的级联效应。这项工作将侧重于卡特里娜飓风的经验，以提供一个试验台，用于审查灾害造成的连锁故障的影响的关键因素和联系。研究设计将利用三个基本技术：关键线人访谈，案例研究和概率模型。 研究工作结束后，应能更清楚地了解危机事件期间主要城市基础设施系统的相互关联性，并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相互关联的脆弱性;（2）更清楚地了解主要基础设施系统中发生的“涟漪”效应;（3）更清楚地了解城市基础设施系统中的脆弱性。3）通过识别系统脆弱性曲线发展过程中的关键输入，提高我们对社区“弹性”建模的能力。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的复原力将有助于深入了解资源的最佳分配，以提高能力和备灾能力。

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.
