Project Activities
Detailed geological and structural surveys were carried out, aimed at mapping the fault and fracture planes, bedding attitude, discontinuities and their relationships with the different water occurrences, in order to reconstruct the possible water migration paths, both of natural and anthropic origin. The surveys in situ were integrated with structural analysis from aerial photographs.
The study also took into consideration the chemical characteristics of the water and the anthropic pressure existing outside the archaeological complex, including the water supply and sewerage networks.
In conclusion, a map was drawn up where the risk areas were outlined, i.e. those within which possible water infiltration could have reached the Hypogeum levels, also indicating their direction of migration and suggesting all possible interventions to hinder them.
