r6570 r6576 11 11 \title{Benchmarking an Inundation Model using the December 2004 Indian Ocean Tsunami Impact at Patong Beach} 12 12 13 -------authors-----------13 %-------authors----------- 14 14 % FIXME(Ole): The 'ands' appear in the text, they shouldn't 15 15 \author{J.D.~Jakeman$^1$~~and~~O.~Nielsen$^2$~~and~~R.~Mleczko$^2$~~and~~K.~VanPutten$^2$~~and~~S.G~Roberts$^1$} … … 142 142 143 143 The domain was discretised into approximately ...,000 triangles. The resolution of the grid was increased in certain regions to efficiently increase the accuracy of the simulation. The grid resolution ranged between a maximum triangle area of $...\times 10^5$ m$^2$ near the Western ocean boundary to $...$ m$^2$ in the small regions surrounding the inundation region in Patong Bay. Due to a lack of available data, friction was set to a constant througout the computational domain. A Manning's coefficient of 0.01 was chosen based upon previous numerical experiments conducted by the authors (FIXME: Citation Tom Baldock?? Or Duncan??). 144 145 The boundary condition at each side of the domain towards the south and the north where no data was available was chosen as a transmissive boundary condition effectively replicating the time dependent wave height present just inside the computational domain. Momentum was set to zero. Other choices include applying the mean tide value as a Dirichlet type boundary condition but experiments as well as the result of the verification reported here showed that this approach tends to under estimate the tsunami impact due to the tempering of the wave near the side boundaries. FIXME(OLE): Should we include Nick's test example? 144 146 145 147 %================Section====================== … … 176 178 \begin{figure}[ht] 177 179 \begin{center} 178 \includegraphics[width=8.0cm,keepaspectratio=true]{Patong_0_8lowres.jpg} 180 %\includegraphics[width=8.0cm,keepaspectratio=true]{Patong_0_8lowres.jpg} 181 \includegraphics[width=8.0cm,keepaspectratio=true]{Depth_small_transmissive_d0.jpg} 179 182 \caption{Simulated inundation versus observed inundation} 180 183 \label{fig:inundationcomparison1cm}
