Geotechnics for Catastrophic Flooding Events presents the keynote lectures (book, 264 pages) and keynote lectures and general papers (CD-ROM, 608 pages) presented at the Fourth International ISSMGEConference on Geotechnical Engineering for Disaster Mitigation and Rehabilitation (4th GEDMAR, Kyoto, Japan, 16-18 September 2014). The contributions discuss hurricane, rainstorm and storm surge induced riverine and coastal flooding events, such as the 2004 Sumatra earthquake in Indonesia, the 2005 Hurricane Katrina disaster in New Orleans, USA, Typhoon Morakot, which devastated parts of Taiwan in 2009 and the 2011 earthquake and tsunami disaster in Eastern Japan, when combined failure mechanisms, multiple hazards, and rare events with huge consequences occurred. The book is divided into the following sections: - Keynote lectures - Liquefaction experiment and analysis project (LEAP) - Guidelines and recommendations for local governments to mitigate flooding disasters - Materials and modeling - Natural hazards - Disaster mitigation and rehabilitation Geotechnics for Catastrophic Flooding Events will be of interest to researchers, academics, industry practitioners and other professional involved in earthquake geotechnical engineering, foundation engineering, and earthquake engineering and structural dynamics.
