Numerical Study on Tsunami Hazard Mitigation Using a Submerged Breakwater
Most coastal structures have been built in surf zones to protect coastal areas. In general, the transformation of waves in the surf zone is quite complicated and numerous hazards to coastal communities may be associated with such phenomena. Therefore, the behavior of waves in the surf zone should be carefully analyzed and predicted. Furthermore, an accurate analysis of deformed waves around coa...
متن کاملAnalytical and numerical study of nonlinear effects at tsunami modeling
The giant tsunami occurred in the Indian Ocean on 26th December 2004 pays attention to this natural phenomenon and the possibility to use the analytical methods. The given paper demonstrates the role of nonlinear effects in the computed dynamics of the tsunami waves in shallow seas and the applicability of the rigorous and approximated solutions of the nonlinear theory of water waves to explain...
متن کاملObject-based image analysis to support numerical tsunami modeling
In response to tsunami disaster at the early stage, integrating remote sensing products with numerical modeling proved to be useful to enhance the capability of early damage estimation. The information derived from high-resolution satellite images would well represent the current status of the surface roughness and the land use conditions that would be used in the numerical modeling of tsunami ...
متن کاملFault parameters of the 1896 Sanriku Tsunami Earthquake estimated from Tsunami Numerical Modeling
The June 15, 1896 Sanriku earthquake generated devastating tsunamis with the maximum run-up of 25 m and caused the worst tsunami disaster in the history of Japan, despite its moderate surface wave magnitude (Ms=7.2) and weak seismic intensity. This is a typical tsunami earthquake, which generates anomalously larger tsunamis than expected from its seismic waves. Previously proposed mechanisms of...
متن کاملCharacteristics of the 2011 Tohoku Tsunami and introduction of two level tsunamis for tsunami disaster mitigation
Characteristics of the 2011 Tohoku Tsunami have been revealed by collaborative tsunami surveys extensively performed under the coordination of the Joint Tsunami Survey Group. The complex behaviors of the mega-tsunami were characterized by the unprecedented scale and the low occurrence frequency. The limitation and the performance of tsunami countermeasures were described on the basis of tsunami...
