Numerical simulation of tsunamis — Its present and near future

摘要: Hindcasting of a tsunami by numerical simulations is process lengthy and complicated deductions, knowing only the final results such as run-up heights tide records, both which are possibly biased due to an insufficient number records hydraulic mechanical limitation gauges. There many sources error. The initial profile, determined with seismic data, can even be different from actual profile. scheme introduces errors. Nonlinearity near on land requires appropriate selection equations. Taking these facts into account, it should noted that produce satisfactory information for practical use, because error usually within 15% far maximum height concerned.
