Tsunamis are ocean waves generated by an impulsive geophysical event, such as an earthquake. Historically, Hawaii and Alaska have been the areas of the U.S. affected by tsunami impact. The objective of this research program is to study the runup of a tsunami onto a coastline, the overland flow of tsunamis, and their interaction with structures located in the nearshore regions. Specifically, it is investigating: (1) The shape, kinematic characteristics and shoreward limit of propagation of the overland flow of the surge which may develop at the shoreline due to the tsunami. (2) The determination of the forces and pressures imposed on two-dimensional and three-dimensional structures by an impinging surge. This investigation is directed toward the mitigation of tsunami hazards by contributing to the knowledge needed: to improve tsunami warning systems, to estimate the overland flow of a tsunami-induced surge, and to design structures located near the shoreline which could be impacted by such a surge.

海啸是由地球物理脉冲产生的海浪 事件，如地震。 历史上，夏威夷和阿拉斯加 是美国受海啸影响的地区。 的 这项研究计划的目的是研究一个 海啸冲击海岸线，海啸的陆上流动， 它们与近岸结构的相互作用 地区 具体而言，它正在调查： (1)形状、运动特征及向岸界限 的蔓延的陆上流动的激增， 可能会因为海啸而在海岸线上发展。 (2)确定施加于 二维和三维结构， 冲击波 这次调查是针对减轻海啸 通过提供所需知识来消除危害： 海啸预警系统，以估计陆地流量的一个 海啸引起的浪涌，并设计位于附近的结构 海岸线可能会受到这样的冲击。
