Abstract

This study shows the practical application of numerical techniques for tsunami simulation. Our techniques were tested against a model problem of flow with linear bottom friction over a parabolic bottom topography. A governing system of partial differential equations was spatially discretized over a triangular mesh. Standard ODE solvers were applied to the resultant system of ordinary differential equations for the horizontal fluxes and the wave height. At each time step, each node was tested to determine whether it was “wet” or “dry”, according to criteria on the total depth. An initial displacement was set according to source fault plane generated by other authors. Our techniques were applied to the Mentawai 2010 tsunami simulation and the Indian Ocean 2004 tsunami simulation. Keywords— Numerical techniques, parabolic bottom topography, standard ODE solver, tsunami simulation.
数值技术在海啸模拟中的应用
本研究显示了数值技术在海啸模拟中的实际应用。我们的技术在抛物线底部地形的线性底部摩擦流模型问题上进行了测试。在三角网格上对偏微分方程控制系统进行空间离散化。将标准ODE求解器应用于水平通量和波高的常微分方程组。在每个时间步,根据总深度的标准,对每个节点进行测试,以确定其是“湿”还是“干”。根据其他作者生成的震源断层面,设定了初始位移。我们的技术应用于2010年明打威海啸模拟和2004年印度洋海啸模拟。关键词:数值技术,抛物线底地形,标准ODE求解器,海啸模拟。
