Hydrosphere Disaster Laboratory
Faculty of Societal Safety Sciences, Kansai University

About the laboratory

We investigate preparedness and mitigation measures for the hydrosphere disaster such as tsunami, storm surge and flooding. Furter, we engage in renewable energy and coral reaf restoration, because environmental problems are also long-term disasters.
