Scale dependence of the hydraulic properties of a fractured aquifer estimated using transfer functions
(2016-07)
Article
Accés obertWe present an investigation of the scale dependence of hydraulic parameters in fractured media based on the concept of transfer functions (TF). TF methods provide an inexpensive way to perform aquifer parameter estimation, ... -
Simulating degradation of organic compounds accounting for the growth of microorganisms (Monod kinetics) in a fully Lagrangian framework
(2022-12)
Article
Accés restringit per política de l'editorialBiologically mediated degradation of organic compounds in porous media is a complex mathematical problem, described by a non-linear differential equation. The organic compound gets in contact with the biomass, and an ... -
Solute transport in bounded porous media characterized by Generalized Sub-Gaussian log-conductivity distributions
(Elsevier, 2021-01)
Article
Accés obertThere are increasing evidences that probability distributions and associated statistical moments of a variety of hydrogeological and soil science variables and their spatial increments display distinctive scale-dependent ... -
Stochastic estimation of hydraulic transmissivity fields using flow connectivity indicator data
(2017-01)
Article
Accés obertMost methods for hydraulic test interpretation rely on a number of simplified assumptions regarding the homogeneity and isotropy of the underlying porous media. This way, the actual heterogeneity of any natural parameter, ... -
Taller de pràctiques de laboratori d'hidrologia subterrània mitjançant models físics experimentals
(Universitat Politècnica de Catalunya. Institut de Ciències de l'Educació, 2013-02-08)
Comunicació de congrés / Text en actes de congrés
Accés obertEn cap de les assignatures de grau d'hidrologia subterrània s'imparteixen pràctiques de laboratori. Això fa que l'estudiant rebi una educació purament teórica sense aaribar a assolir correctament els conceptes bàsics ... -
The effects of sediment depth and oxygen concentration on the use of organic matter: an experimental study using an infiltration sediment tank
(2015-04-02)
Article
Accés obertWater flowing through hyporheic river sediments or artificial recharge facilities promotes the development of microbial communities with sediment depth. We performed an 83-day mesocosm infiltration experment, to study ... -
The role of advection and dispersion in the rock matrix on the transport of leaking CO2-saturated brine along a fractured zone
(Elsevier, 2016-12)
Article
Accés obertCO2 that is injected into a geological storage reservoir can leak in dissolved form because of brine displacement from the reservoir, which is caused by large-scale groundwater motion. Simulations of the reactive transport ... -
Transverse effective dispersion coefficients in a chemically heterogeneous medium with flow fluctuations
(2006)
Text en actes de congrés
Accés obertWe investigate the effective transport of a sorptive solute through a chemically heterogeneous medium subject to temporal fluctuations of the flow conditions. We focus on linear instantaneous sorption, with a spatially ... -
Vadose zone oxygen (O2) dynamics during drying and wetting cycles: An artificial recharge laboratory experiment
(Elsevier, 2015-05-02)
Article
Accés obertVadose zone oxygen dynamics control all subsurface redox reactions and play a decisive role in maintaining groundwater quality. Although drying and wetting events are common in artificial recharge, their effects on subsurface ... -
What are the main factors influencing the presence of faecal bacteria pollution in groundwater systems in developing countries?
(2020-01)
Article
Accés obertGroundwater is the major source of drinking water in most rural areas in developing countries. This resource is threatened by the potential presence of faecal bacteria coming from a variety of sources and pollution paths, ...
