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.

(European Association of Geoscientists & Engineers (EAGE), 2017)
Comunicació de congrés
Accés restringit per política de l'editorialThe results of the geophysical survey reflects the presence of heterogeneity distribution of electrical resistivity values. This allowed to delimit the geometry of the three layers, as indicated by borehole logging. At the ... -
Feasibility of two low-cost organic substrates for inducing denitrification in artificial recharge ponds: batch and flow-through experiments
(2017-03)
Article
Accés restringit per política de l'editorialAnaerobic batch and flow-through experiments were performed to assess the capacity of two organic substrates to promote denitrification of nitrate-contaminated groundwater within managed artificial recharge systems (MAR) ... -
Elimination of the reaction rate 'scale effect': application of the Lagrangian reactive particle-tracking method to simulate mixing-limited, field-scale biodegradation at the Schoolcraft (MI, USA) site
(2017-12)
Article
Accés restringit per política de l'editorialMeasured (or empirically fitted) reaction rates at groundwater remediation sites are typically much lower than those found in the same material at the batch or laboratory scale. The reduced rates are commonly attributed ... -
A comparison of Eulerian and Lagrangian transport and non-linear reaction algorithms
(Elsevier, 2017-01)
Article
Accés restringit per política de l'editorialWhen laboratory-measured chemical reaction rates are used in simulations at the field-scale, the models typically overpredict the apparent reaction rates. The discrepancy is primarily due to poorer mixing of chemically ... -
Evaluación de las medidas de humedad de suelo generadas con datos disgregados de satélite a escala de parcela agrícola

Text en actes de congrés
Accés obertEl interés de medir la humedad de suelo a escala de parcela de cultivo mediante teledetección ha aumentado debido a la fácil disponibilidad de los datos y, que a diferencia de los sensores de humedad de suelo, no es necesario ... -
Temperature driven vapor fluxes in soils cause a net recharge
(2017)
Comunicació de congrés
Accés obertTemperature gradients can drive vapor diffusion by controlling vapor pressure in the soil. We studied vapor diffusion for soils in two different climates: A semiarid climate at El Cabril (Córdoba, Spain) and a subarctic ... -
