Barrier effect of underground structures on aquifers
Pujades Garnes, Estanislao; López, Ander; Carrera Ramírez, Jesús; Vázquez Suñé, Enric; Jurado Elices, Anna (2012)
Article
Accés restringit per política de l'editorialImpervious structures below the water table modify the natural groundwater flow in aquifers. They act as barriers, causing heads to rise upgradient and to fall downgradient. We define the barrier effect as the increase in ... -
Changes in hydrodynamic, structural and geochemical properties in carbonate rock samples due to reactive transport
Martínez Pérez, Laura; Luquot, Linda; Carrera Ramírez, Jesús (Elsevier, 2017-01)
Article
Accés obertReactive transport plays an important role in the development of a wide range of both anthropic and natural processes affecting geological media. To predict the consequences of reactive transport processes on structural ... -

Luquot, Linda; Roetting, Tobias Stefan; Carrera Ramírez, Jesús (2014-08-01)

Article
Accés obertThe characterization of saline water intrusion (SWI) and its hydrodynamics is a key issue to understand submarine groundwater discharge (SGD) and manage groundwater resources in coastal areas. To test and compare different ... -
Compositional formulation for multi phase flow reactive transport in porous media: an approach that simplifies coupling between phenomena
Gamazo Rusnac, Pablo Andres; Saaltink, Maarten Willem; Carrera Ramírez, Jesús (Centro Internacional de Métodos Numéricos en Ingeniería (CIMNE), 2010)
Text en actes de congrés
Accés obertIn this work we discuss coupling difficulties that arises when solving phase and species conservation equations. We present a compositional formulation that avoids these difficulties, and allows solving multiphase reactive ... -
Coupling of mass transfer and reactive transport for nonlinear reactions in heterogeneous media
Willmann, Mathias; Carrera Ramírez, Jesús; Sánchez Vila, Francisco Javier; Silva Rojas, Orlando Enrique; Dentz, Marco (2010-07-01)
Article
Accés obertFast chemical reactions are driven by mixing‐induced chemical disequilibrium. Mixing is poorly represented by the advection‐dispersion equation. Instead, effective dynamics models, such as multirate mass transfer (MRMT), ... -
Deep enclosures versus pumping to reduce settlements during shaft excavations
Pujades Garnes, Estanislao; Vázquez Suñé, Enric; Carrera Ramírez, Jesús; Vilarrasa Riaño, Víctor; De Simone, Silvia; Jurado Elices, Anna; Ledesma Villalba, Alberto; Ramos Schneider, Gonzalo; Lloret Morancho, Antonio (2014-02-04)
Article
Accés restringit per política de l'editorialDeep excavations in aquifers may be constructed by combining pumping with the cut and cover method. The enclosures are often deepened more than structurally needed, in order to diminish the risk of heave or fluidisation ... -
Dewatering of a deep excavation undertaken in a layered soil
Pujades Garnes, Estanislao; Vázquez Suñé, Enric; Carrera Ramírez, Jesús; Jurado Elices, Anna (2014-08-21)
Article
Accés restringit per política de l'editorialIn order to carry out deep excavations under the water table in urban environments, the safety of the work site and of the adjacent buildings is a major cause for concern. One of the most common and effective methods of ... -
Dissolution patterns and mixing dynamics in unstable reactive flow
Hidalgo, Juan J.; Dentz, Marco; Cabeza Diaz de Ceiro, Yoar; Carrera Ramírez, Jesús (2015-08-16)
Article
Accés obertWe study the fundamental problem of mixing and chemical reactions under a Rayleigh-Taylor-type hydrodynamic instability in a miscible two-fluid system. The dense fluid mixture, which is generated at the fluid-fluid interface, ... -
Dynamics of water vapor flux and water separation processes during evaporation from a salty dry soil
Gran Esforzado, Meritxell; Massana, Jordi; Carrera Ramírez, Jesús; Saaltink, Maarten Willem; Olivella Pastallé, Sebastià; Ayora Ibáñez, Carlos; Lloret Morancho, Antonio (Elsevier, 2011-01)
Article
Accés restringit per política de l'editorialEvaporation from a salty soil generates salt accumulation near the surface with the subsequent deterioration of the soil quality. Salinization mechanisms are poorly understood despite their global impact. Vapor flux and ... -
