Efficient algorithms for wave problems

Boris Bonev

Wave phenomena manifest in nature as electromagnetic waves, acoustic waves, and gravitational waves among others. Their descriptions as partial differential equations in electromagnetics, acoustics, and fluid dynamics are ubiquitous in science and engineer ...

A comparative study of earthquake source models in high- order accurate tsunami simulations

Jan Sickmann Hesthaven, Boris Bonev

The discontinuous Galerkin method is used to solve the non-linear spherical shallow water equations with Coriolis force. The numerical method is well-balanced and takes wetting/drying into account. The two fold goal of this work is a comparative study of d ...

Numerical approach in the study of tsunami-like waves and comparison with experimental data

Giovanni De Cesare, Michael Pfister, Davide Wüthrich

A comprehensive understanding of physical phenomena based on a hybrid experimental-numerical approach supports a safer design of critical infrastructures. However, for large-scale tsunami-like waves, the reliability of numerical models was insufficiently v ...

Discontinuous Galerkin scheme for the spherical shallow water equations with applications to tsunami modeling and prediction

Jan Sickmann Hesthaven, Boris Bonev

We present a novel high-order discontinuous Galerkin discretization for the spherical shallow water equations, able to handle wetting/drying and non-conforming, curved meshes in a well-balanced manner. This requires a well-balanced discretization, that can ...

Estimation of wave propagation velocity on a channel with smooth and rough bed

Anton Schleiss, Michael Pfister, Davide Wüthrich

Natural hazards such as tsunamis, impulse waves and dam-break waves are rare, but extremely destructive. In recent times, more importance was given to structures that could withstand such events, however, uncertainties still exist in the estimation of wave ...

Explaining the physics of tsunamis to undergraduate and non-physics students

Giorgio Margaritondo

After the recent devastating tsunami in southern Asia, I tried to find a simple way to present the physics of this phenomenon to students-in particular, the origin of the dispersion relation and the consequent wave properties. Being unable to locate a suit ...
