Teizan Canal

Abstract

Teizan Canal is a shore-parallel canal, 49 km long along Sendai Coast, Japan. Although the canal was seriously damaged during the 2011 Great East Japan Earthquake Tsunami, field observation results indicate that the canal contributed to tsunami disaster reduction, such as delayed tsunami arrival and effective drainage of tsunami return flow. In this study, after introducing the history of the canal, a series of numerical experiments will be shown for actual and hypothetical cross-sections of the canal to investigate the effectiveness of canal shape for reducing tsunami impact.
