  Heat storage efficiency, ground surface uplift and thermo-hydro-mechanical phenomena for high-temperature aquifer thermal energy storage 

  Vidal Montes, Rubén; Olivella Pastallé, Sebastià; Saaltink, Maarten Willem; Diaz-Maurin, François Carlos León (2022-10)
  Article
  Open Access

  High-temperature aquifer thermal energy storage (HT-ATES) systems can help in balancing energy demand and supply for better use of infrastructures and resources. The aim of these systems is to store high amounts of heat ...
• Tritium transport in non-saturated concrete under temperature fluctuations 

  Chaparro, Maria Carme; Saaltink, Maarten Willem (Elsevier, 2022-10)
  Article
  Restricted access - publisher's policy

  This work studies the effect of the environmental conditions on tritium transport in concrete cells storing radioactive waste. Water with high concentration of tritium was leaking from drains situated in these concrete ...

  Modeling the organic carbon oxidation and redox sequence under the partial-equilibrium approach: a discussion by means of a semi-analytical solution 

  Saaltink, Maarten Willem; Rodríguez Escales, Paula-Felicidad (2022-07)
  Article
  Open Access

  In this work, we have developed a semi-analytical solution for organic carbon oxidation coupled to the reduction-oxidation sequence assuming the Partial Equilibrium Approach (PEA) and using the decoupling procedure of De ...

  On the localization of chemical reactions in multicontinuum media 

  Wang, Jingjing; Carrera Ramírez, Jesús; Saaltink, Maarten Willem; Valhondo González, Cristina (Elsevier, 2022-09)
  Article
  Open Access

  Reactive transport (RT) through heterogeneous media, may cause chemical heterogeneity if water flux is slow through portions of the medium. In such cases, chemical localization (i.e., the occurrence of reactions that would ...

  Dynamic management zones for irrigation scheduling 

  Fontanet Ambrós, Mireia; Scudiero, Elia; Skaggs, T.H.; Fernández García, Daniel; Ferrer, Fernado; Rodrigo, G; Bellvert, Joaquim (2020-08)
  Article
  Open Access

  Irrigation scheduling decision-support tools can improve water use efficiency by matching irrigation recommendations to prevailing soil and crop conditions within a season. Yet, little research is available on how to support ...
• Simulating degradation of organic compounds accounting for the growth of microorganisms (Monod kinetics) in a fully Lagrangian framework 

  Dawi, Malik Ali A.; Sánchez Vila, Francisco Javier (2022-12)
  Article
  Restricted access - publisher's policy

  Biologically 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 ...

  Hydromechanical characterization of tide-induced head fluctuations in coastal aquifers: The role of delayed yield and minor permeable layers 

  Goyetche, Tybaud; Pool, Maria; Carrera Ramírez, Jesús; Luquot, Linda (Elsevier, 2022-09-01)
  Article
  Open Access

  Tidal analysis is an aquifer scale testing that is a low-cost alternative to pumping tests for evaluating aquifer hydraulic parameters without groundwater extraction. Many analytical solutions may be used to assess aquifer ...

  Enhanced NAPL removal and mixing with engineered injection and extraction 

  Wang, Yufei; Fernández García, Daniel; Solé Marí, Guillem; Rodríguez Escales, Paula-Felicidad (2022-04)
  Article
  Open Access

  Aquifer remediation with in-situ soil washing techniques and enhanced oil removal typically involves the injection of liquid solutions into the geological formation to displace and mobilize non-aqueous phase liquids (NAPLs). ...
• Power assisted MFC-based biosensor for continuous assessment of microbial activity and biomass in freshwater ecosystems 

  Fernández Gatell, Marta; Sánchez Vila, Francisco Javier; Puigagut Juárez, Jaume (Elsevier, 2022-08)
  Article
  Restricted access - publisher's policy

  Microbial activity and biomass are important factors that determine nutrient and carbon fluxes in freshwater ecosystems and, therefore are also related to both water quality and climate change induced stressors. This study ...
• Water mixing approach (WMA) for reactive transport modeling 

  Soler Sagarra, Joaquim; Saaltink, Maarten Willem; Nardi Ricart, Albert; Gaspari, Francesca de; Carrera Ramírez, Jesús (Elsevier, 2022-03-01)
  Article
  Restricted access - publisher's policy

  We describe a formulation to solve reactive transport (RT) problems. The basic idea is to represent transport as mixing water instead of individual solute concentrations, hence the Water Mixing Approach (WMA) name. This ...
• A closer look: high-resolution pore-scale simulations of solute transport and mixing through porous media columns 

  Solé Marí, Guillem; Bolster, Diogo; Fernández García, Daniel (2022-01)
  Article
  Restricted access - publisher's policy

  Mixing is pivotal to conservative and reactive transport behaviors in porous media. Methods for investigating mixing processes include mathematical models, laboratory experiments and numerical simulations. The latter have ...

  Combined simulation and optimization framework for irrigation scheduling in agriculture fields 

  Fontanet Ambrós, Mireia; Fernández García, Daniel; Rodrigo, G; Ferrer, Francesc; Villar Mir, Josep Maria (Springer Nature, 2022-01)
  Article
  Open Access

  In the context of growing evidence of climate change and the fact that agriculture uses about 70% of all the water available for irrigation in semi-arid areas, there is an increasing probability of water scarcity scenarios. ...
