Un modelo 1D NPZ de acoplamiento entre la hidrodinámica y los flujos biogeoquímicos en estrechos bicapa. Aplicación a la dinámica mareal en el Estrecho de Gibraltar
Macías-Sánchez, Jorge
; Castro-Díaz, Manuel Jesús; Fernández-Nieto, Enrique (CEDYA 2013/IMAC/Universitat Jaume I, 2013)
Los modelos NPZ (siglas para Nutrientes-Fitoplancton-Zooplancton en inglés) son comúnmente utilizados en estudios de biología marina. Este tipo de modelos utiliza un conjunto de ecuaciones diferenciales muy sencillo para ... -
Non-linear shallow water models for coastal run-up simulations
Macías-Sánchez, Jorge; González-Vida, José Manuel; Castro-Díaz, Manuel Jesús (European Geosciences Union, 2013)
Shallow water models are frequently used to simulate ocean or coastal circulation or tsunami wave propagation. But these models are seldom used to explicitely reproduce for example tsunami wave run-up into coast. In this ... -
Numerical analysis of some nonlinear hyperbolic systems of Partial Differential Equations arising from Fluid Mechanics
(UMA Editorial, 2021-11-10)En esta tesis se abordan cuatro problemas diferentes relacionados con el análisis numérico de sistemas de ecuaciones en derivadas parciales hiperbólicos no lineales. Estos problemas están relacionados con la resolución ... -
Numerical tool for tsunami risk assessment in the southern coast of Dominican Republic
Macías-Sánchez, Jorge; Llorente, Miguel; Ortega, Sergio; González-Vida, José Manuel; Castro-Díaz, Manuel Jesús (2017-02-06)
The southern coast of Dominican Republic is a very populated region, with several important cities including Santo Domingo, its capital. Important activities are rooted in the southern coast including tourism, industry, ... -
On the efficient implementation of PVM methods and simple Riemann solvers. Application to the Roe method for large hyperbolic systems
Pimentel García, Ernesto; Parés-Madroñal, Carlos María; Castro-Díaz, Manuel Jesús; Koellermeier, Julian (Elsevier, 2021-01-01)
Polynomial Viscosity Matrix (PVM) methods can be considered as approximations of the Roe method in which the absolute value of the Roe matrix appearing in the numerical viscosity is replaced by the evaluation of the Roe ... -
Semi-implicit well-balanced schemes for 1D shallow flows.
(UMA Editorial, 2024)En esta tesis se abordan algunos problemas relacionados con la resolución numérica de sistemas hiperbólicos de leyes de equilibrio. En particular, se tratan el sistema constituido por las ecuaciones de aguas someras o aguas ... -
Simulación numérica de tsunamis generados por avalanchas submarinas: aplicación al caso de Lituya-Bay
(2014-06-23)En este trabajo se aborda el diseño de esquemas numéricos para leyes de conservación con productos no conservativos y términos fuente basados en resolverdores de Riemann aproximados. Consideraremos el esquema de Roe y el ... -
Testing Tsunami Inundation Maps for Evacuation Planning in Italy
Tonini, Roberto; Di Manna, Pio; Lorito, Stefano; Selva, Jacopo; Volpe, Manuela; Romano, Fabrizio; Basili, Roberto; Brizuela, Beatriz; Castro-Díaz, Manuel Jesús; de la Asunción, Marc; Di Bucci, Daniela; Dolce, Mario; Garcia, Alexander; Gibbons, Steven; Glimsdal, Sylfest; González-Vida, José Manuel; Lovholt, Finn; Macías-Sánchez, Jorge; Piatanesi, Alessi; Pizzimenti, Luca; Sánchez-Linares, Carlos; Vittori, Eutizio[et al.] (Frontiers, 2021-03-11)
Inundation maps are a fundamental tool for coastal risk management and in particular for designing evacuation maps and evacuation planning. These in turn are a necessary component of the tsunami warning systems’ last-mile. ... -
The Lituya Bay landslide-generated mega-tsunami – numerical simulation and sensitivity analysis
González-Vida, José Manuel; Macías-Sánchez, Jorge; Castro-Díaz, Manuel Jesús; Sánchez-Linares, Carlos; de la Asunción, Marc; Ortega-Acosta, Sergio; Arcas, Diego[et al.] (Copernicus Publication, 2019-02-15)
The 1958 Lituya Bay landslide-generated mega- tsunami is simulated using the Landslide-HySEA model, a recently developed finite-volume Savage–Hutter shallow wa- ter coupled numerical model. Two factors are crucial if the ... -
Uncertainty quantification in tsunami modeling using multi-level Monte Carlo finite volume method
Sánchez-Linares, Carlos; De-la-Asunción-Hernández, Marc; Castro-Díaz, Manuel Jesús; González-Vida, José Manuel; Macías-Sánchez, Jorge; Mishra, Siddhartha[et al.] (SpringerOpen, 2016-06-08)
Shallow-water type models are commonly used in tsunami simulations. These models contain uncertain parameters like the ratio of densities of layers, friction coefficient, fault deformation, etc. These parameters are modeled ... -
Use of Neural Networks for Tsunami Maximum Height and Arrival Time Predictions
Rodríguez Gálvez, Juan Francisco; Macías-Sánchez, Jorge; Castro-Díaz, Manuel Jesús; De-la-Asunción-Hernández, Marc (IOAP-MPDI, 2022-06-13)
Operational TEWS play a key role in reducing tsunami impact on populated coastal areas around the world in the event of an earthquake-generated tsunami. Traditionally, these systems in the NEAM region have relied on the ... -
Well-balanced methods for compressible Euler equations with gravitational force that preserve transonic stationary solutions.
Gómez Bueno, Irene; Castro-Díaz, Manuel Jesús; Parés-Madroñal, Carlos María (Springer, 2024-06-06)
In some previous works, the authors introduced a general methodology to design high-order well-balanced finite-volume methods for one-dimensional systems of balance laws based on the use of well-balanced state reconstructions. ... -
