Flow plot of arrows at t = 5.4 s of <strong>the</strong> <strong>2D</strong> model.The <strong>to</strong>tal computation time for this <strong>2D</strong> model hasbeen 7m 30s with a processor Intel Pentium 4 CPU2.53 GHz <strong>and</strong> 1 GB RAM.A similar model with flat bot<strong>to</strong>m bathymetry has beenimplemented as it was done for <strong>the</strong> <strong>1D</strong> model <strong>to</strong>demonstrate <strong>the</strong> big influence of <strong>the</strong> bathymetry in <strong>the</strong>results.Figure 35h.
