Coastal Effects of Tsunamis II

本行动是为了将NSF支持的一项研究项目（BCS-8715450）延长一年。该项目的目标是更好地了解海啸（地震海浪）在影响沿海地区时的破坏性作用。外延拓展了研究范围；它也提供了一个机会来重新分析在过去五年的研究中获得的大量实验室实验数据。这种扩展的动机来自于前面获得的结果。目的是全面了解破碎海啸（钻孔）在倾斜海滩上传播的基本行为；海啸对海岸的影响；以及随后的上升和下降过程。这些现象对于理解海啸到达沿海地区时的破坏性影响至关重要。

This action is for a one-year extension to a research program (BCS-8715450) supported by NSF: the goal of this project is to develop a better understanding of the destructive action of a tsunami (seismic sea wave) as it impacts a coastal zone. The extension expands the research scope; it also provides an opportunity to reanalyze the extensive quantity of laboratory experimental data obtained during the past five years of research. The motivation for this extension arises from the results obtained previously. The objective is to develop a thorough understanding of the fundamental behavior of broken tsunami (bore) propagation up a sloping beach; the tsunami actions at the shore; and the ensuing runup and drawdown processes. These phenomena are fundamental to an understanding of the destructive effect of a tsunami as it reaches a coastal zone.
