Numerical Simulation and Experimental Study on Tsunami Propagation and Run-up and the influence of Submerged Breakwater on Run-up

The southern coasts of Iran are exposed to tsunami waves due to Makran subduction. Therefore, understanding the propagation and run-up of tsunami waves through numerical simulation and experimental studies is vital. In this research, by applying OpenFOAM computational fluid dynamics open source Software, propagation and run-up of tsunami waves in different conditions are estimated and the results of numerical simulations are compared with experimental data. Solitary waves are considered as the model for tsunami waves. Initially, the propagation of non-breaking and then the breaking solitary wave as two-dimensional numerical simulation has been investigated. The effect of submerged obstacle on the decreasing run-up is studied numerically and experimentally. The results show that OpenFOAM software model the propagation precisely and predicts the wave run-up with acceptable level of accuracy in numerous wave conditions. Furthermore, results shows the submerged obstacle can reduce up to 19.7 percent of the tsunami run up.
