Analysis of water vapor adsorption in soils by means of a lysimeter and numerical modeling
(2020-04)
Article
Open AccessDaily temperature oscillations can cause adsorption (and desorption) of atmospheric water vapor by soils. The resulting daily fluctuations in the amount of liquid water in the soil can be measured by high-precision weighing ... -
Analytical solution to assess the induced seismicity potential of faults in pressurized and depleted reservoirs
(2021-01)
Article
Open AccessDisplaced faults crossing the reservoir could significantly increase the induced earthquake frequency in geo-energy projects. Understanding and predicting the stress variation in such cases is essential to minimize the ... -

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 ... -
Comparing precision lysimeter rainfall measurements against rain gauges in a coastal dune belt, Spain
(Elsevier, 2020-12)
Article
Restricted access - publisher's policyPrecipitation measurements are performed mostly by simple automatic rain gauges installed at a certain level above the ground surface, but these methods are often affected by significant measurement errors due to the ... -
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
