SIMULATION OF TSUNAMI-INDUCED FLOOD IN HINTERLAND OF SEAWALL BY USING PARTICLE METHOD

Complicated characteristics of tsunami induced flood at a vertical seawall, including overflowing jet and run-up over a hinterland are reproduced by the gridless Lagrangian flow model, or the particle method. Detailed behavior of flow, which is characterized by an overflowing jet, circulating flow cell and a hydraulic jump, is simulated on both of a uniform slope and a horizontal bed with bar-type roughness.
