Il Tevere e il suo antico corso

In this paper, the results of a scientific collaboration between the Institute of Etrusco-Italic Archaeology, the Institute of Technologies Applied to Cultural Heritage and the Civic Museum of Magliano Sabina are presented. The aim of this research is to study the distribution of archaeological sites in the territory of Magliano Sabina (Tiber Valley) and their relationship with the environmental-historical context. This area is a section of the Tiber Valley, where the river has always represented an important element from an historical point of view. In the present day in this area the river no longer follows its original course, so it was decided to find its old course in order to better understand the distribution of the ancient settlements in this territory. On the basis of research carried out at the Archivio di Stato di Roma it was possible to verify that the river Tiber originally flowed in the lower part of Magliano Sabina, nowadays the area of "Piana di Ramelli". The study of historical cartography allowed us to verify the change of the river course since 1589, the year of the construction of the "Felice" bridge. The data has been confirmed by the morphological and geological characterisation of the selected study area. A GIS of the area has been used to compare and integrate all data sets with the aim of producing thematic maps to better understand the environmental evolution of the territory of Magliano Sabina.
