홈페이지논문 초록 (Abstract)
In the present study, it is examined the tsunami modelling sensitivity to the various input factors based on the simulation results of 2004 Indian Ocean Tsunami. The numerical tests were implemented using coupled shallow water equation model, COMCOT(Liu et al., 1998) a nd Boussinesq model(Son et al., 2011) on the multi-grid system. Fou r different configurations(CASE 1 through 4) where three factors w ere controlled independently had been set up and simulated. From the numericalresults, it was examined that some of defined factors may have control over the level of prediction accuracy in tsunami i mpacts on the nearshore area. It was shown that hydrodynamic performan ces calculated by Boussinesq model(Son et al., 2011) were very dist inct from those by COMCOT-only. Most importantly, this study also su ggests that more thorough and dedicated investigations on the diffusiv e errors embedded inherently in numerical models are required for the fu ture study.
