EFFECT OF MACRO-ROUGHNESS ELEMENTS ON TSUNAMI INUNDATION: SINK TERM FORMULAE FOR DEPTH-AVERAGED NUMERICAL MODELS

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...

Numerical Flood Simulation by Depth Averaged Free Surface Flow Models

Numerical Investigation of Island Effects on Depth Averaged Fluctuating Flow in the Persian Gulf

In the present paper simulation of tidal currents on three-dimensional geometry of the Persian Gulf is performed by the solution of the depth averaged hydrodynamics equations. The numerical solution was applied on two types of discritized simulation domain (Persian Gulf); with and without major islands. The hydrodynamic model utilized in this work is formed by equations of continuity and motion...

Numerical simulation of lava flows based on depth-averaged equations

Risks and damages associated with lava flows propagation (for instance the most recent Etna eruptions) require a quantitative description of this phenomenon and a reliable forecasting of lava flow paths. Due to the high complexity of these processes, numerical solution of the complete conservation equations for real lava flows is often practically impossible. To overcome the computational diffi...

Tsunami Inundation Mapping for Alaska Communities

Alaska has the greatest tsunami potential in the entire United States. Historic tsunamis generated by earthquakes on the Alaska-Aleutian subduction zone have resulted in widespread damage and loss of life along the Alaskan Pacific coast and other places located at exposed locations around the Pacific Ocean. Large seismic events occurring in the vicinity of the Alaska Peninsula, Aleutian Islands...
