Proposal for the creation of an environmental disaster-prevention coastal town through the effective use of sand dunes

Research grant

Project Description

The research quantitatively evaluates the disaster prevention and disaster reduction effect against tsunami, along with their limitations, through tsunami disaster surveys, tsunami experiments and numerical calculations. In order to improve the Erosion Resilience of sand dunes necessary as a storm surge barrier, investigations will be made through experiments and calculations of the introduction effect of reinforcement methods. The role of sand dunes in sand dune eco-system conservation will also be demonstrated, with the objective of proposing the creation of an environmental disaster-prevention coastal town through the effective use of sand dunes. Based on this result, in addition to making a proposal for reconstruction measures for the flat plain areas that were affected, various town planning guidelines will also be presented for coastal regions with sand dune coastlines.

Research record
The research representative is ingaged in hydraulic engineering research from both the environmental and disaster prevention aspects.
Environment
  • (1) Clarifying the state of environmental burdens, and surveying their impact on lakes and in-bay environments (Focusing on Tokyo Bay, Teganuma and the Inbanuma area)
  • (2) Development and verification tests of land burden reduction technology
  • (3) Development of land environment burden-related monitoring and modelling technology
Disaster prevention
  • (1) Storm disaster survey (2010) Amami storm disaster etc.)
  • (2) Tsunami survey (2011 Great East Japan Earthquake)
