| Research Abstract |
Real-time tsunami prediction methods by a neural network method and a inverse estimation method, which can be performed in several tens of minutes at most, were developed based on ocean-site-observed information after occurrence of an earthquake. The possibility of tsunami prediction for the Tohoku Earthquake was actually examined by the inversion method. In addition, computer fluid simulation techniques were developed and applied to analyses of interaction between tsunami fluid motion and tsunami barrier named as flap-gate. The possibility of the flap-gate to protect and reduce tsunami motion was verified from the numerical simulations and laboratory experiments.
