There are numerous reports of large-scale "whirlpools" being generated in the near-shore during tsunami events (Borrero et al., 2015). These features, termed tsunamiincluded turbulent coherent structures (TCS), form due to flow separation at sharp coastline features. During the 2011 Tohoku tsunami, the generation of a large-scale TCS was captured at port Oarai in a helicopter footage (Lynett et al., 2012). The TCS was spinning for tens of minutes, entraining boats in the high-speed rotational flow, until it was washed away by the next incoming wave. TCS generation can potentially control the hazard for small amplitude tsunami waves in ports and harbors (Borrero et al., 2015; Kalligeris et al., 2016).
