This action is to support a group research project focusing on specific aspects of tsunami coastal hazards mitigation. To mitigate tsunami coastal hazards, the first priority is to improve the identification of the tsunami-inundation zone. Recently, NOAA (National Oceanographic and Atmospheric Administration) has launched a comprehensive program to estimate potential inundation zones along the coastal areas of the Pacific States (California, Oregon, Washington, Alaska and Hawaii; http://www.pmel.noaa.gov/tsunami/time/). The next level of mitigation strategy is to reduce loss of life and property damage within the tsunami inundation zones by considering the runup process in detail: flow patterns, induced forces, the impact of debris and floating objects, and their implication for improved design of waterfront structures and decisions concerning land use.The five primary objectives are to:Understand the fundamental turbulence phenomena associated with tsunami runup and its effects on tsunami forces on structures and scouring;Improve the prediction capability of tsunami runup models, by more accurately including the effects of dispersion and wave breaking;Achieve a practical means of describing the complex runup flows within the context of their interactions with structures, trees and other typical complex coastal features (e.g. dunes, earthen dikes and river intlets);Develop benchmark problems and their solutions for validating numerical models and for determining the adequacy of different approximations for different applications in tsunami hazard reduction;Develop scenarios focusing on four interrelated issues: single and multiple structures (rectangular and cylindrical forms), porous media, missiles/debris impacts, and scouring.The project involves researchers from Cornell University, Southern Methodist University, the University of Washington, Urban Regional Research, and a Professor Emeritus from Harvard University. In addition, it includes collaboration on scouring during tsunami runup with researchers at Japan's Public Works Research Institute (PWRI), using PWRI's large and unique experimental facility.

该行动是为了支持一个小组研究项目，重点介绍了海啸危害缓解的特定方面。 为了减轻海啸危险，首要任务是改善海啸资源的识别。 最近，NOAA（国家海洋学和大气管理局）启动了一项综合计划，以估算太平洋州沿海地区（加利福尼亚，俄勒冈州，华盛顿，阿拉斯加和夏威夷； 下一个缓解策略的下一个水平是通过考虑详细的运行过程来减少海啸淹没区内的寿命和财产损失：流动模式，诱导力，碎屑和浮动物体的影响以及它们对滨水结构的改进设计的影响，与五个主要目标相关的效果。 tsunami forces on structures and scouring;Improve the prediction capability of tsunami runup models, by more accurately including the effects of dispersion and wave breaking;Achieve a practical means of describing the complex runup flows within the context of their interactions with structures, trees and other typical complex coastal features (e.g. dunes, earthen dikes and river intlets);Develop benchmark problems and their solutions for validating numerical models and for确定不同近似值在海啸危害中的不同应用的适当性；开发着专注于四个相互关联的问题：单个和多个结构（矩形和圆柱形形式），多孔媒体，导弹/碎片影响，搜索和搜索。 此外，它还包括使用PWRI的大型且独特的实验设施，在海啸中与日本公共工程研究所（PWRI）的研究人员进行搜查。
