Landslide Wave and Tsunami Eddy
Coherent structures are known to form in many types of shallow geophysical flows, where the horizonal length scale of the flow feature is much larger than the vertical flow confinement. In this work, we study the generation and evolution of wave-induced shallow turbulent coherent structures (TCS) through a series of large-scale experiments in a wave basin. This research is motivated by numerous reports on the formation of large-scale eddies in ports and harbors during tsunamis. We present our findings on the scaling of TCS growth, the TCS kinetic energy decay timescale, and the scaling of the three-dimensional TCS flow components.
