The Disaster Potential Study Laboratory identifies destructive mechanisms of disasters in coastal areas and rivers, such as tsunamis, storm surges, high waves, flood, droughts and environmental contaminations, in order to quantify disaster risks and develop efficient disaster prevention/mitigation measures. There are concerns about the increase of disasters caused by sea level rise, changes in annual rainfall and glacial melt due to climate change, and these factors are also important subjects of our studies.

Our main research projects are as follows:

  • Mechanisms of coastal levee destruction and coastal erosion due to the 2011 tsunami
  • Projection of beach disappearance due to sea-level rise and proposal of effective adaptation measures
  • Physically–based numerical modeling and action-oriented approach to mitigate typhoon- and flood-related disasters in Japan and Southeast Asia
  • Glacial melt and catchment modeling for various climate change scenarios
  • Changes in the water chemistry of coastal marine systems and the sustainable development of offshore aquaculture after the 2011 earthquake
(Please see our website [http://potential1.civil.tohoku.ac.jp/topEN.html] for more information) We have conducted field surveys for clarifying the mechanisms of coastal levee destruction and coastal erosion due to the 2011 tsunami and evaluating damage caused by Typhoon Haiyan in the Philippines in 2013 (Figure 1).
