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

Year Of Curation: 2013

Description: 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.
