... and the size of the sand. INTRODUCTION Tsunami when approaching the coast carries multiple sediments, stones and debris of different size. These debris often reinforce hazardous impact of tsunami waves on coast and coastal structures, therefore it is very important to know their dynamics. The propagation...

... ABSTRACT Increasing population density in coastal regions raises the risk of catastrophic tsunami damage. Traditional protection measures like seawalls are effective but costly and may create a false sense of security. However, strategically placed buffer blocks along the coastlines can...

... ABSTRACT This study investigated the energy attenuation by a vegetation patch against the extreme flow by considering two flow models (Solitary wave and dam-break generated flow) from the literature that represent the tsunami-like flow. The protection level provided by a vegetation belt...

... ABSTRACT This thesis investigates the collision force of driftwoods and small boats due to tsunamis. Even though there are some calculation formulas from past experiments, quantitative approaches for design criteria of tsunami protection structures are not established. Accordingly, to upgrade...

... successive solitary waves can be generated and superimposed on the surge wave, and the experimental data show good repeatability. A profile of the undular bores simulated by numerical computation is well reproduced in the basin. INTRODUCTION Tsunami is one of the devastating natural hazards, which may...

... ABSTRACT There has been an increasing number of studies on the tsunami hazards in the South China Sea region since the 2004 Sumatra earthquake. Many of them are carried out based on tsunami scenario simulations, which adopt seismic source models constructed from scaling relations between...

... Abstract The trapping effect of oceanic ridge plays an important role on the far-field tsunami propagation pattern though the trapping mechanism is still unknown. Based on the linear shallow water equations, the trapped modes over a symmetric parabolic-profile submerged ridge are obtained...

... ABSTRACT: At present no methodology exists to evaluate the failure mode of a caisson breakwater subjected to a tsunami attack. The present paper investigates the sliding and tilting failure of a caisson breakwater subjected to a solitary wave attack, and establishes a relationship between...

... the beginning of earthquake there is a deformation anomaly of the big size. The size of deformation anomaly registered by laser strainmeter is connected to size of mixture of a bottom in an epicenter of earthquake. The given displacement also results in formation of a tsunami. The deformation anomaly registered...
