The 31st International Symposium on Shock Waves (ISSW31) will be held July 9-14, 2017, at Toyoda Auditorium, Nagoya University, Nagoya, Japan. This will be the third ISSW held in Japan, after 26 years...
Liquefaction potential of coastal slopes induced by solitary waves
Coastal slopes Liquefaction Tsunami Wave–seabed interaction
2015/7/1
Tsunami runup and drawdown can cause liquefaction failure of coastal fine sand slopes due to the generation of high excess pore pressure and the reduction of the effective over burden pressure during ...
