Coastal Disaster Mitigation in Transdisciplinary Approach

Our research aims to develop novel disaster mitigation technologies, focusing on coastal disasters such as tsunamis, storm surges, and coastal erosion. Disaster prevention studies in the 20th century have been a straightforward discipline, purely oriented toward the goal of preventing disasters. However, as the mid-21st century approaches, we believe that the role of disaster research is to leverage the investment of disaster mitigation to create something new with socially and economically more benefit. For example, coastal vegetation such as mangroves can be actively utilized to improve natural environment, and it can enhance disaster prevention functions and even reduce maintenance of existing coastal infrastructure. Or, huge flood gates could be converted to generate tidal power to supply electricity to the local community. We are not bound by precedent, but fully utilize our experience and knowledge to achieve top-level novel research on the world stage.

Costal Disaster Research for Asian Countries

Coastal disasters such as tsunamis, storm surges, and high waves lead to considerable loss of human life and property. The vulnerability of coastal areas against natural disaster is expected to increase due to economic development and climate or environmental changes, especially for developing coasts such as found in many Asian countries, in which a large number of the population highly depends on low-lying vulnerable coastal areas. Our research team is pursuing to understand what are actually exacerbating the coastal disaster risks especially in developing countries by means of field surveys, numerical simulations, and physical experiments.
