SUMMARY:Dispersive Tsunami-HySEA Model for Faster Than Real Time Tsunami S
 imulations
DESCRIPTION:Minisymposium\n\nDispersive Tsunami-HySEA Model for Faster Tha
 n Real Time Tsunami Simulations\n\nEscalante, Castro, Macías\n\nThis work 
 aims to develop and implement a numerical model, including dispersion suit
 able for tsunami simulations. Therefore, including more physics but still 
 computing much Faster than Real-time. The main problem is that state-of-th
 e-art dispersive models do not have a hyperbolic character, such as the st
 andard Shallow Water equations. In practice, that forces to solve a linear
  system at each time step of the simulation (see [2,3]), otherwise a restr
 ictive CFL condition must be considered, losing the computational efficien
 cy. We will present a latitude-longitude coordinate formulation to account
  for the effects of curvature, and we have proposed a dispersive model tha
 t is hyperbolic following ideas described in [1]. We will show some simula
 tions on real test cases and computational times using GPU architectures t
 hat show promising results with excellent computational efficiency.<br />[
