IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Three-dimensional numerical analysis of fluid flow and rigid body motion

ABSTRACT
Huge tsunamis damage infrastructure seriously and kills or injures many people. A flap gate breakwater is one of the
possible novel countermeasures against a tsunami attack. The performance in the event of a tsunami should be
validated. In this paper, the applicability of a three-dimensional numerical analysis model, which was developed in our
previous study and calculates fluid flow and rigid body motion simultaneously, to the wave response simulation of a flap
gate breakwater was studied. First, the model was applied to a hydraulic experiment with a flap gate breakwater and the
calculation accuracy was verified. Second, a real-size calculation with a virtual flap gate breakwater during a tsunami
attack was simulated and the possibility for the real-size performance validation by the model was indicated.
