Resumen
Literary and historical sources provide information about Late Roman forests in the Delta of the River Po, in the district of Ferrara (Italy), between Vicus Aventiae (Voghenza), Sandalo, Gambulaga, Caput Gauri (Codigoro) and Castrum Cumiacli (Comacchio). Toponymy, archaeological excavations and geoarchaeological studies support the palaeoenvironmental reconstruction of this land. In this work, after a brief examination of the ancient texts, we are going to introduce some new data concerning archaeobotanical evidence, detected by remote sensing in combination with direct surveys (on land and underwater). On the technical side, we are going to present a geomatic application for underwater measurements of ancient trunks related to discoveries in the palaeo-watercourses of the River Po (geomatic measurements, thanks to remote sensing surveys, allows us to have detailed length and diameters of trunks and trees, which are not always visible and detectable while diving) together with some satellite elevation measurement of the river banks and 3D map supported by geocomputation. Thanks to botanical data, we are able to illustrate the local context of the paleoenvironmental/archaeological sites, offering a reconstruction of the landscape and of the use of the wood.
