1. Two-Way Multiscale Coupling for Tsunami Modeling: Application to the Kamaishi Offshore Breakwater
Numerical modeling of potential tsunami hazards allows for customized information on the estimated impacts for individual coastal communities and harbors. In order to capture the full desired local effects, e.g. around coastal structures, a three-dimensional Navier-Stokes model may be adopted in the region of interest. To facilitate this the Navier-Stokes model can be coupled with a shallow water model so that the entire evolution of the tsunami is simulated. In this talk, such a coupled model is presented and applied to model flow near the large-scale offshore tsunami breakwater in Kamaishi during the 2011 Tohoku-oki Earthquake Tsunami, Japan. Analysis of the effects on inundation, flow at the breakwater, and the pressure forces on the caissons are discussed.

William Pringle is currently a postdoc in the Computational Hydraulics Laboratory, Notre Dame working under Joannes Westerink on the application and development of wave and circulation models applied to the coastal ocean. He got his Bachelor or Engineering at the University of Canterbury, Christchurch, New Zealand, before moving to Kyoto, Japan for his graduate studies. He recently obtained his PhD from the Graduate School of Engineering, Kyoto University in March, William’s thesis focussed on facilitating three-dimensional simulations of tsunamis and other waves through coupling with a two-dimensional model
