On 26 August 2025, within the framework of the European project Interreg VI-A Italy–Slovenia WABIN, researchers from OGS – National Institute of Oceanography and Applied Geophysics, in collaboration with the University of Ljubljana, carried out a geophysical survey near Miren (Merna).
During the fieldwork, two geoelectrical lines were acquired along the profiles already surveyed in February. This approach made it possible to compare data collected in two different seasons – winter and summer – with the aim of identifying potential variations in the water content of the sediments lying above the bedrock.
In parallel, the researchers also performed the acquisition of self-potential, a passive geophysical technique that measures natural variations in the electric potential of the soil. These variations may be caused by natural processes such as water flow (electrokinetic potential) or chemical reactions between water and rocks (electrochemical potential).
This activity represents an important step forward in improving the understanding of groundwater dynamics in the cross-border area and in developing innovative approaches for the sustainable management of water resources.
