The synthesis of decades of groundwater knowledge: the new Hydrogeological Map of Rome

This paper describes the contents and the path taken to get to the new Hydrogeological map of the City of Rome. The map, which is the result of a combination of “expert elaborations” and GIS processing performed using the most recent available data, extends to the entire municipality (1285 km2) and is based on both the most recent scientiἀc studies on groundwater ἀeld and new survey activities carried out in order to ἀll the data gaps in several areas of the examined territory. The work represents also an example of inter-institutional collaboration between government agencies, research institutes and universities
