; González-Vida, José Manuel
[et al.] (Elsevier, 2013)
The numerical solutions of shallow water equations are useful for applications related to geophysical flows that usually take place in large computational domains and could require real time calculation. Therefore, parallel ... -
GPU computing for shallow water flow simulation based on finite volume schemes.
Castro-Díaz, Manuel Jesús; Ortega-Acosta, Sergio
; de la Asunción, Marc; Mantas, José M.; Gallardo-Molina, José María
; de la Asunción, Marc[et al.] (Elsevier, 2011)
This article is a review of the work that we are carrying out to efficiently simulate shallow water flows. In this paper, we focus on the efficient implementation of path-conservative Roe type high-order finite volume ... -
HySEA model verification for Tohoku 2011 Tsunami. Application for mitigation tsunami assessment
Macías-Sánchez, Jorge; González-Vida, José Manuel
; García, Javier; Castro-Díaz, Manuel Jesús
; Ortega, Sergio; De la Asunción, Marc[et al.] (European Geosciences Union, 2015-04)
In many aspects Tohoku-Oki 2011 mega tsunami has changed our perception of tsunami risk. The tsunami-HySEA model is used to numerically simulate this event and observed data will we used to verify the model results. Three ... -

Macías-Sánchez, Jorge; Castro-Díaz, Manuel Jesús
; González-Vida, José Manuel
; De la Asunción, Marc; Ortega, Sergio (EGU, 2014-04)
HySEA numerical model for the simulation of earthquake generated tsunamis is presented. The initial sea surface deformation is computed using Okada model. Wave propagation is computed using nonlinear shallow water equations ... -
Numerical simulation of tsunamis generated by landslides on multiple GPUs.
de la Asunción, Marc; Castro-Díaz, Manuel Jesús; Mantas, José M.; Ortega-Acosta, Sergio
(Elsevier, 2016)
We present a new kind of high-order reconstruction operator of polynomial type, which is used in combination with a high-order finite volume scheme for solving nonconservative hyperbolic systems. The implementation of ... -
