Tsunami Wave Propagation

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...

The VOLNA code for the numerical modelling of tsunami waves: generation, propagation and inundation

A novel tool for tsunami wave modelling is presented. This tool has the potential of being used for operational purposes: indeed, the numerical code VOLNA is able to handle the complete life-cycle of a tsunami (generation, propagation and run-up along the coast). The algorithm works on unstructured triangular meshes and thus can be run in arbitrary complex domains. This paper contains the detai...

Depth-integrated, non-hydrostatic model with grid nesting for tsunami generation, propagation, and run-up

Tsunamis generated by earthquakes involve physical processes of different temporal and spatial scales that extend across the ocean to the shore. This paper presents a shock-capturing dispersive wave model in the spherical coordinate system for basin-wide evolution and coastal run-up of tsunamis and discusses the implementation of a two-way grid-nesting scheme to describe the wave dynamics at re...

Tsunami propagation modelling – a sensitivity study

Indian Ocean (2004) Tsunami and following tragic consequences demonstrated lack of relevant experience and preparedness among involved coastal nations. After the event, scientific and forecasting circles of affected countries have started a capacity building to tackle similar problems in the future. Different approaches have been used for tsunami propagation, such as Boussinesq and Nonlinear Sh...
