Tasks and methodology :
- Active participation in field work at Argentona site (Argentona river basin,
Maresme region), a seawater intrusion monitoring site.
- Study of the dynamics of the seawater intrusion in a coastal aquifer.
- Research on modeling and inversion of geophysical data, together with hydrogeological data.
Effective integration of geological understanding into model inversion remains the single most challenging hurdle for reliable groundwater inversion. The novelty of the procedure we intent to develop lies in including sequential stratigraphy concepts as constraints in the inversion of geophysical and hydrological data for modeling of flow and transport.
In Barcelona province, the Argentona site has been built to monitor the dynamics of seawater intrusion: delineate the shape of the freshwater-saltwater interface, improve our understanding of the mixing process and study the Radium and Radon mobilization through chemical studies.
Inversion will be based on optimizing model fit to hard data on state variables (temperature, heads, conductivity, potential) of fields conditioned to categorical data (textural information from boreholes) and sequential stratigraphy concepts on continuity and orientation of layers. This will allow testing the validity of geological assumptions. The inversion should provide a detailed visualization of the actual processes occurring in the field, which would allow us to gain understanding on the movement of the seawater inland. Specifically, it should allow us to understand Radium mobilization in the freshwater-saltwater mixing zone.
