Determining the Added Hazard Potential of Tsunamis by Interaction with Ocean Swell and Wind Waves (NEES-2010-0954)

<p><strong>Title</strong>: Determining the Added Hazard Potential of Tsunamis by Interaction with Ocean Swell and Wind Waves (NEES-2010-0954)</p> <p><strong>Year Of Curation: </strong>2013</p> <p><strong>Description: </strong>The destructive power of a tsunami on the world's coastlines is unquestioned; ample evidence can be seen in photos of the aftermath of the 2004 Indian Ocean tsunami. The scale of destruction, however, has perhaps inadvertently justified the study of tsunamis in isolation from the other components of the ocean wave climate. The intellectual merit of the proposed work is the investigation of the tsunami phenomenon not as an isolated event, but as an inherent part of the world's ocean climate. For all their differences in destructive power, size, and generation, tsunamis and swell waves (which are always present on the ocean surface) are both gravity waves, and follow many of the same physical laws. Additionally, gravity waves of different frequencies exchange energy, which affects the shape of the front face of the wave and, in turn, the destructive power, travel time, and damage potential (structural damage and erosion) of the tsunami.</p> <p><strong>Award: </strong>http://www.nsf.gov/awardsearch/showAward?AWD_ID=0936579</p> <p><strong>PIs & CoPIs: </strong>James Kaihatu</p> <p><strong>Dates: </strong>October 01, 2009 - September 30, 2011</p> <p><strong>Organizations: </strong>Texas A & M University, TX, United States</p> <p><strong>Facilities: </strong>Oregon State University, OR, United States</p> <p><strong>Sponsor: </strong>NSF - 0936579 </p> <p><strong>Keywords: </strong>Random swell,monochromatic waves,tsunami,free surface measurements,near-bottom velocities,reflection</p> <p><strong>Publications:</strong> Hoda M.

<p><strong>标题</strong>: 通过与海洋涌浪及风浪相互作用确定海啸的附加灾害潜能（NEES-2010-0954）</p>
<p><strong>编目年份</strong>: 2013</p>
<p><strong>项目描述</strong>: 海啸对全球沿海地区的破坏力毋庸置疑，2004年印度洋海啸的灾后影像资料即可提供充分佐证。然而，其灾害规模之大或许让人们无意间倾向于将海啸研究与海洋波浪环境的其他组分割裂开来。本研究的学术价值在于，将海啸现象并非视作孤立事件，而是全球海洋波浪环境的固有组成部分。尽管海啸与始终存在于海洋表面的涌浪在破坏力、规模及生成机制上存在诸多差异，但二者均属于重力波，遵循诸多相同的物理规律。此外，不同频率的重力波会发生能量交换，这会改变波浪锋面的形态，进而影响海啸的破坏力、传播时间以及灾害潜能（包括结构破坏与海岸侵蚀）。</p>
