PhD Title:

GPU Based Hydrodynamic Modelling of Tsunami

 

PhD Project Details:

Tsunami's can be very destructive causing large loss of life.  The recent tsunami, which hit Japan in March 2011, was catastrophic in its effects.  More than 15,000 people were killed, and significant damages were caused to buildings and infrastructure including several power plants.  This project will provide a new practical tool for multi-scale tsunami modelling based on high performance computing.  The project will build upon existing schemes to develop a numerical model for tsunami propagation and inundation.  Tsunami simulations commonly cover large spatial domains.  Therefore, in order to substantially improve computational efficiency, the model is implemented for graphics processing units (GPU) using CUDA.

 

Possible applications include:

  • Evacuation planning

  • Real-time tsunami warning systems

  • Risk management

  • City planning

 

A numerical scheme, which solves the shallow water equations (SWE’s), is employed in this work.  This method is particularly suited to the nature of the tsunami propagation and inundation.  Tsunamis generated by earthquakes are commonly considered as long-waves and can be mathematically described by the non-linear shallow water equations.  This work presents a numerical model which solves the 2D SWE's using a finite volume (FVM) Godunov type scheme incorporating a HLLC approximate Riemann solver.  The scheme is shock capturing and so is applicable to the rapidly varying flows observed in tsunami events.
