Numerical Simulation of Tsunami Flooding Downstream a QuayWall

摘要

In this paper, the interaction of a tsunami and a quay wall is studiednumerically with focus on the water volume flooding the downstreampart of the quay. The model solves the Navier-Stokes equations usingthe VOF method. It is first validated on two cases close to the studyconfiguration. Then flooding discharge are calculated considering twowave inputs (solitary wave, break flow over wet bottom) and increasingamplitudes. The dierences are significant. The solitary wave give ashort duration flooding due to its dependency between amplitude andfrequency. The dam break flow produces flooding bursts followed by asteady residual flooding which may be the parameter of importance inthis problem.
