SGER: GIS Applications in Tsunami Hazard Mitigation

摘要：CMS-9726240， Philip Liu, Cornell U.海啸的发生无法准确预测；相反，有必要通过建立海啸预警系统和实施健全的沿海地区管理政策等措施，集中精力减少损失。现代地理信息系统（GIS）技术为管理数据、与外部分析程序连接以及以对灾害规划、减灾和重建战略比较有用的方式呈现结果提供了强大的工具。这一研究项目的目标是开发一种初步工具，通过将地理信息系统与海啸传播和上升的数值模型结合起来，协助工程师和规划人员减轻海啸危害，从而使工程师和规划人员能够评价将用于数值模型的数据；将模拟练习的结果可视化；并确定潜在的洪水区域，疏散路线以及受影响地区对结构和公用设施的潜在破坏。该项目的重点是建立一个用于减轻海啸危害的地理信息系统框架，以夏威夷希洛作为初步开发的具体地点。+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+= + 诚如Clifford j·阿斯蒂尔所说,Ph值:703-306-1362传真:703-306-0291 castill@nsf.gov Nat威尔逊国际科学Fdn 4201大街。弗吉尼亚州阿灵顿545号邮编22230

ABSTRACT: CMS-9726240, Philip Liu, Cornell U. The occurrence of a tsunami cannot be accurately predicted; instead, it is necessary to focus on reducing the damage through such measures as establishing Tsunami Warning Systems, and by implementing sound coastal zone management policies. Modern geographical information system (GIS) technology provides a powerful tool for managing the data, for interfacing with external analysis programs, and for presenting the results in the manner useful for disaster planning, hazard mitigation, and rehabilitation strategy comparison. The objective of this research project is to develop a preliminary tool to assist engineers and planners in tsunami hazard mitigation by integrating GIS with the numerical models for tsunami propagation and runup, thereby permitting engineers and planners to evaluate the data to be used in the numerical model; to visualize the results from modeling exercises; and to determine potential flooding areas, evacuation routes and the potential damage to structures and utilities in the affected area. The project focuses on establishing the framework of a GIS for tsunami hazard mitigation, using Hilo, Hawaii as the specific site for the preliminary development. +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+= + Clifford J.
