Abstract

Within the framework of a geoarchaeological research project started in 2000, supported by Fondazione Cassamarca, archaeologists, geologists, palynologists, remote sensing specialists and geophysicists of the University of Padua are carrying out joint investigations in the Ca’ Tron area, in the low venetian plain by the inner shores of the Lagoon of Venice. The aim of the work is to understand how human settlements have been interacting with the dynamic environmental conditions of this coastal area. The prominent archaeological feature in the study area is a stretch of the Roman via Annia, built in the 2nd century B.C., but archaeological evidences span, at the moment, since the Eneolithic to the Middle Ages, according to the continuity of use of the roman road. The archaeological landscapes which have been reconstructed, related to the different time slices and cultural phases, are frames within the overall palaeoenvironmental evolution of the area during the last 20,000 years, driven by glacio-climatic and eustatic cycles, palaeohydrographic changes and local subsidence.The mapping of the main landforms has been carried out on an area of about 140 km2, through the interpretation of a large set of multiscale and multitemporal images. A detailed DTM has been derived from 0.5 m contour lines and spot heights with decimetric resolution, and used both as a tool for geomorphological analyis and as a support for 3D digital modelling. The subsurface sediments and soils have been investigated on an area of ca. 11 km2 through the boring of 50 cores within a depth of 5 m, and 13 down to a maximum depth of 20 m. Several radiocarbon datings of peat and wood fragments helped in tracing the chronostratigraphic framework. Pollen analyses have been performed on selected samples, collected in both archaeological and natural suitable contexts, detected by remote sensing.Remote sensing served as a guide to the archaeological survey, leading to the detection of traces of anthropic origin. Some of these latter have been investigated with geophysical prospections, while, in other cases, trial trenches and archaeological excavations have been carried out. All information is stored in digital format and georeferenced within a GIS. This has been allowing a proper management of spatial data, and is also crucial to a future goal of the Ca’ Tron project, which is the reconstruction of archaeological landscapes with 3D immersive virtual reality technology.
