Tsunami Modelling using the Well-Balanced Scheme
نویسندگان
چکیده
A well balanced numerical scheme based on stationary waves for shallow water flows with arbitrary topography has been introduced by Thanh et al. [18]. The scheme was constructed so that it maintains equilibrium states and tests indicate that it is stable and fast. Applying the well-balanced scheme for the one-dimensional shallow water equations, we study the early shock waves propagation towards the Phuket coast in Southern Thailand during a hypothetical tsunami. The initial tsunami wave is generated in the deep ocean with the strength that of Indonesian tsunami of 2004. Keywords—Tsunami study, shallow water, conservation law, well-balanced scheme, topography. Subject classification: 86 A 05, 86 A 17.

Quadtree-adaptive tsunami modelling
The well-balanced, positivity-preserving scheme of Audusse et al, 2004, for the solution of the Saint-Venant equations with wetting and drying, is generalised to an adaptive quadtree spatial discretisation. The scheme is validated using an analytical solution for the oscillation of a fluid in a parabolic container, as well as the classic Monai tsunami laboratory benchmark. An efficient database...
متن کاملHigh Resolution Methods and Adaptive Refinement for Tsunami Propagation and Inundation
We describe the extension of high resolution finite volume methods and adaptive refinement for the shallow water equations in the context of tsunami modeling. Godunov-type methods have been used extensively for modeling the shallow water equations in many contexts, however, tsunami modeling presents some unique challenges that must be overcome. We describe some of the specific difficulties asso...
متن کاملA robust and well-balanced scheme for the 2D Saint-Venant system on unstructured meshes with friction source term
In the following lines we propose a numerical scheme for the shallow water system supplemented by topography and friction source terms, in a 2d unstructured context. This work proposes an improved version of the well-balanced and robust numerical model recently introduced in [J. Comp. Phys., 235, 565–586, 2013] for the pre-balanced Shallow Water Equations, accounting for varying topography. The...
متن کاملSwitching fuzzy modelling and control scheme using T-S fuzzy systems with nonlinear consequent parts
This paper extends the idea of switching T-S fuzzy systems with linear consequent parts to nonlinear ones. Each nonlinear subsystem is exactly represented by a T-S fuzzy system with Lure’ type consequent parts, which allows to model and control wider classes of switching systems and also reduce the computation burden of control synthesis. With the use of a switching fuzzy Lyapunov function, the...
متن کاملVulnerability assessment towards tsunami threats using multisensoral remote sensing data [7478-54]
The occurrence of a tsunami, a set of oceans waves caused by any large, abrupt disturbance of the sea surface, hitting a vulnerable system on land can cause massive loss of life, destruction of coastal infrastructure and disruption of economic activity. Vulnerability assessment and risk modelling are important components for an effective end-to-end hazard early warning system and therefore cont...
