Groundwater and Hydrogeochemistry

The Groundwater and Hydrogeochemistry group studies the hydraulic, chemical, thermal and mechanical processes that take place in porous media from pore to regional scale. The group employs mathematical and numerical approaches as well as laboratory and field scale experiments and sampling methods (using hydraulic, hydro-geochemical and environmental isotope data sampled directly or through specifically designed tests).

The group is active in the development of numerical and mathematical models and modelling techniques for complex porous media processes across spatial and temporal scales, laboratory and field scale experimentation and sampling and data analysis. This includes geospatial data and information management.

Applications include the assessment and management of groundwater resources, groundwater and soil remediation, the management of urban aquifers, the study of emerging pollutants in urban aquifers and artificial recharge facilities, the study of wetlands, seawater intrusion in coastal aquifers, water management in mining operations, civil works, storage of waste and/or its recovery, water decontamination methodologies, the study of the unsaturated zone, the study of the hydro-thermo-mechanical and chemical processes associated with the injection and extraction of fluids at great depth (storage of CO2, storage of nuclear waste, geothermal energy, shale gas, induced seismicity).

Free and open source, QGIS-integrated interface for planning and management of water resources, with specific attention to groundwater


An open source tool for water quantity and quality management


The software platform (QUIMET) was developed to improve the sorting, analysis, calculations, visualizations, and interpretations of hydrogeochemical data in a GIS environment.


Generation of 3D geological models of sedimentary media for hydrogeological modelling


Development of innovative software to analyze pumping tests in a GIS platform to support the hydraulic parameterization of groundwater flow and transport models


Creation of a Graphical User Interface (GUI) that automatically generates the input and reads the output of PHREEQC for a specific water mixing analysis


Mixing calculations involve computing the ratios in which two or more end-members are mixed in a sample. Mixing calculations are useful for a number of tasks in hydrology, such as hydrograph separation, water or solute mass balances, and identification of groundwater recharge sources


Evaluation of water balance per unit of soil area as a function of precipitation, the potential evapotranspiration (or ETP), temperature and irrigation
