Abstract

In contrast to many post-tsunami studies focusing on tsunami inundation heights, this study focuses mainly on tsunami flooding flow directions, which may have more direct impact on damages of structures. Based on tilted poles and trees in the inundated area, this study collected data of tsunami flow directions at Rikuzen-takata, Ootsuchi, and Naraha on the east coast of Japan. Numerical tsunami inundation model was then applied to each of these sites to investigate the relationship between simulated time-varying flow patterns and observed flow directions. Such link is essentially important to deepen our understandings on the dynamics of the inundation tsunami flow.
