GHS - Grup d'Hidrologia Subterrània

 

El Grup d'Hidrologia Subterrània realitza recerca, docència i transferència del coneixement a la societat en el camp de la hidrogeologia i la geoquímica. Està format per personal de UPC i CSIC que es complementen, interaccionant i formant sinèrgies. El GHS treballa en la caracterització de mitjans permeables a través de dades hidràuliques i hidroquímiques. Les aplicacions comprenen l’avaluació de recursos d'aigua subterrània, gestió d'aqüífers, estudi de zones humides, intrusió marina i emmagatzematge subterrani de residus i CO2.

The Hydrogeology Group studies the characterisation of permeable media using hydraulic and hydrochemical data as well as environmental isotopes. The applications developed consist in the study of groundwater resources, aquifer management, humid and swamp zones, salt water intrusion, underground residual storage and the unsaturated zone. The quantitative methods used, such as the numerical modelling of flow and mass transport, focus on the regional or local scale. Some of the group?s members carry out numerical modelling and others work on data acquisition. The group often collaborates with the International Hydrogeology Centre.

  • Water mixing approach (WMA) for reactive transport modeling 

    Soler Sagarra, Joaquim; Saaltink, Maarten Willem; Nardi Ricart, Albert; De Gaspari, Francesca; 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. ...

  • The multi-advective water mixing approach for transport through heterogeneous media 

    Soler Sagarra, Joaquim; Hakoun, Vivien; Dentz, Marco; Carrera, Jesús (2021-10-12)
    Article
    Open Access
    Finding a numerical method to model solute transport in porous media with high heterogeneity is crucial, especially when chemical reactions are involved. The phase space formulation termed the multi-advective water mixing ...

  • A general and efficient numerical solution of reactive transport with multirate mass transfer 

    Wang, Jingjing; Carrera Ramírez, Jesús; Saaltink, Maarten Willem; Valhondo González, Cristina (2022-01)
    Article
    Open Access
    The presence of low permeability regions within porous media impacts solute transport and the distribution of species concentrations. Therefore, (bio)chemical reactions are equally affected. Multirate Mass Transfer (MRMT) ...

  • Microbial activity enhancement in constructed wetlands operated as bioelectrochemical systems 

    Fernández Gatell, Marta; Corbella Vidal, Clara; Sánchez Vila, Francisco Javier; Puigagut Juárez, Jaume (2022-01)
    Article
