In the framework of the Italian-Slovenian transboundary cooperation program
2007-2013, the HYDROKARST Project that aims at the protection and management of the
Classical Karst transboundary aquifer is being carried out. Since the second half of 1800,
several studies in this research field have been realized, but Hydrokarst is an opportunity for
joint work for a unique goal, enriching the knowledge of a precious resource, water. In this
context, in order to better define the groundwater flow dynamics, a joint monitoring network
consisting of devices for continuous recording of physical parameters as electrical
conductivity, temperature and water level, was realized. For selected water points, several
physico-chemical, microbiological and geochemical surveys were performed. Major ions,
δ18O and87Sr/86Sr isotopic ratio were analyzed. Fauna samples were collected. Additionally, a
water-tracing test with fluorescent dye was carried out.
