Three Dimensional Numerical Simulation of Tsunami Generation and Propagation Due to Makran Subduction and run-up on Chabahar Bay and Makran Coasts

Makran subduction located at the northwest of the Indian Ocean nearby the southern coast of Iran and Pakistan. Makran subduction is the source of tsunamis that threaten southern coast of Iran. In this article, generation and propagation of 1945’s tsunami initiated by Makran subduction is simulated. For the three dimensional generation of the wave, advanced algorithm of Okada is adopted. The CFD...

Numerical modeling of wave run-up along columns of semi-submersible platforms

Wave run-up is one of the most important and effective parameters in designing semi-submersible platforms. Besides unforeseen effects on the movements and response of the platform, wave run up can also cause slamming forces to be exerted on the lower deck of the platform. Therefore, at the first stages of this plan, before running tests on the model of the platform, numerical methods are usuall...

ISPH Numerical Modeling of Nonlinear Wave Run-up on Steep Slopes

Non-breaking tsunami waves run-up on steep slopes can cause severe damages to coastal structures. The estimation of the wave run-up rate caused by tsunami waves are important to understand the performance and safety issues of the breakwater in practice. In this paper, an Incompressible Smoothed Particle Hydrodynamics method (ISPH) method was utilized for the 2DV numerical modeling of nonli...

Numerical modeling of wave propagation, breaking and run-up on a beach

A numerical method for free-surface flow is presented at the aim of studying water waves in coastal areas. The method builds on the nonlinear shallow water equations and utilizes a non-hydrostatic pressure term to describe short waves. A vertical boundary-fitted grid is used with the water depth divided into a number of layers. A compact finite difference scheme is employed that takes into acco...
