(2011-01-01)
Article
Restricted access - publisher's policyThe performance and reliability of the CWM1-RETRASO model for simulating processes in horizontal subsurface flow constructed wetlands (HSSF CWs) and the relative contribution of different microbial reactions to organic ... -
Characterization of concrete by calibrating thermo-hydraulic multiphase flow models
(2015-08-01)
Article
Open AccessEvaporation tests in concrete columns have been analysed by numerical models to characterize the thermo-hydraulic properties and the processes in concrete. Two evaporation tests were performed: a column heated by a lamp ... -
Combining fiber optic DTS, cross-hole ERT and time-lapse induction logging to characterize and monitor a coastal aquifer
(Elsevier, 2020-09)
Article
Restricted access - publisher's policyThe 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
(Centro Internacional de Métodos Numéricos en Ingeniería (CIMNE), 2010)
Conference report
Open AccessIn 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 ... -
CWM1 implementation in RetrasoCodeBright: first results using horizontal subsurface flow constructed wetland data, Chemical Engineering Journal
(2011-01-01)
Article
Restricted access - publisher's policyConstructed Wetland Model No. 1 (CWM1) processes were implemented within RetrasoCodeBright (RCB) to simulate hydraulics and reactive transport as well as the main biodegradation and transformation processes in horizontal ... -
Dynamics of water vapor flux and water separation processes during evaporation from a salty dry soil
(Elsevier, 2011-01)
Article
Restricted access - publisher's policyEvaporation 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 ... -
Evaluation of self-combustion risk in tire derived aggregate fills
(2011-09)
Article
Restricted access - publisher's policyLightweight tire derived aggregate (TDA) fills are a proven recycling outlet for waste tires, requiring relatively low cost waste processing and being competitively priced against other lightweight fill alternatives. However ... -
Experimental and modeling investigation of multicomponent reactive transport in porous media
(2011-01-01)
Article
Restricted access - publisher's policyWe present an experimental and modeling study of solute transport in porous media in the presence of mixing-induced precipitation of a solid phase. Conservative and reactive transport experiments were performed in a ... -
