Outline of Final Research Achievements

In the reconstruction of the tsunami -stricken area of the Great East Japan Earthquake, there was a discrepancy between the government, which showed the seawall plan for disaster prevention, and the local residents who wanted to prioritize the landscape of the waterfront. As a result, there were areas where the consensus formation of the reconstruction plan was delayed.
In this study, the problem of the construction of seawalls is revealed. Next, we conducted an action research on the construction of landscape town development with seawall construction in a tsunami -affected area due to the Nankai Trough Earthquake. As a result, we proposed an urban design method that can balance "disaster prevention" and "waterfront landscape".

Academic Significance and Societal Importance of the Research Achievements

これまで、土木分野において防潮堤の研究が進められてきたが、本研究では、防潮堤に隣接する建築のデザインや、地区全体の土地利用及び災害危険区域の指定などの建築分野や都市計画分野の視点から、都市デザインの手法を開発した点が、学際的意義としてあげられる。
本研究で開発した都市デザインの手法は、切迫する南海トラフ大地震による津波被災想定地域における防潮堤整備の推進する際に、行政と地域住民の間で合意形成を図る上で有効であり、各自治体の景観まちづくりの推進に寄与するという点が社会的意義としてあげられる。
