Simulating tsunami propagation in fjords with long-wave models

Tsunamis induced by rock slides constitute a severe hazard towards coastal fjord communities. Fjords are narrow and rugged with steep slopes, and modeling the shortfrequency and high-amplitude tsunamis in this environment is demanding. In the present paper, our ability (and the lack thereof) to simulate tsunami propagation and run-up in fjords for typical wave characteristics of rock-slide-indu...

Tsunami Wave Propagation

Adaptive modelling of long-distance wave propagation and fine-scale flooding during the Tohoku tsunami

The 11th March 2011 Tohoku tsunami is simulated using the quadtree-adaptive SaintVenant solver implemented within the Gerris Flow Solver. The spatial resolution is adapted dynamically from 250 metres in flooded areas up to 250 km for the areas at rest. Wave fronts are tracked at a resolution of 1.8 km in deep water. The simulation domain extends over 73◦ of both latitude and longitude and cover...

A new numerical model for simulating the propagation of and inundation by tsunami waves A new numerical model for simulating the propagation of and inundation by tsunami waves

A new unstructured grid, finite volume ocean model is described, that is suitable for flooding and drying problems. Here we derive the finite volume analogue of the P 1 −P1 finite element, by interpreting the advective term in the continuity equation in a flux sense. A corresponding non-overlapping control volume is then selected for the momentum equation. The resulting model employs the median...

Wave Propagation in Sandwich Panel with Auxetic Core

Auxetic cellular solids in the forms of honeycombs and foams have great potential in a diverse range of applications, including as core material in curved sandwich panel composite components, radome applications, directional pass band filters, adaptive and deployable structures, filters and sieves, seat cushion material, energy absorption components, viscoelastic damping materials and fastening...
