NUMERICAL SIMULATION OF TSUNAMI CURRENTS

Eizo Nakaza, Tsunakiyo Iribe, Muhammad Abdur Rouf

Abstract


The paper aims to simulate Tsunami currents around moving and fixed structures using the moving-particle semi-implicit method. An open channel with four different sets of structures is employed in the numerical model. The simulation results for the case with one structure indicate that the flow around the moving structure is faster than that around the fixed structure. The flow becomes more complex for cases with additional structures.
