[P01-28] Real-Time Tsunami Simulations with Surrogate Modeling
キーワード：Proper Orthogonal Decomposition, Surrogate Modeling, Tsunami
There have been many numerical models proposed for tsunami propagation simulations. They are all very numerically intensive, requiring days to complete the calculations. For probabilistic risk analysis, which requires many simulations, these methods are infeasible. Therefore, in this paper, we propose a framework of surrogate modeling, which introduces the potential of real-time risk assessment. To create the surrogate model, we calculated the prominent modes of the given data, after which we used RBF interpolation for mapping the input data points to their corresponding coefficients. The surrogate model this constructed is expected to be accurate, given the simulation cases used are sufficiently dense for the complexity of the results.
