Physical Modeling of Tsunami Waves Impact on Shore Structures

Kantardgi I. G., Akulinin A. N.

Tsunami research is a very complex applied problem. Even a partial solution of this problem will significantly mitigate catastrophic destruction and reduce the number of human casualties after this natural phenomenon. In the process of tsunami studying physical modeling often provides the additional information for numerical simulation. First of all, this is the information about the interaction of tsunamis with the complex design constructions and possible destruction of these constructions. Such information is, in principle, can be obtained using a CFD simulation method. However, CFD model also requires verification by the laboratory data. There are many ways to conduct tsunami simulation and many methods of tsunami wave generation. The most widespread and studied way of wave generation is moving block method. The method of wave generation using special wave paddles or shields is also used. In recent times, a fundamentally new way of tsunami simulating was developed. New pneumatic tsunami generator consists of a tank with water and vacuum pump. Each of the methods has its advantages and disadvantages.
