ROMAN PORTS IN THE LOWER TIBER VALLEY: COMPUTATIONAL APPROACHES TO REASSESS ROME'S PORT SYSTEM

This paper presents an innovative study of the port system of Rome in Imperial times through the application of an integrated approach to both archaeological analysis and material evidence. Specifically, it seeks to provide a more complete contextualization and understanding of the port system of Rome by focusing on the exploration of the physical geography of the river Tiber and its transformations in connection with the organization of the port system between the late first century BC and early third century AD. Methodologically, this study is based on the compilation, re-evaluation and analysis of published archaeological and geoarchaeological data and on the application of modelling and simulations techniques within a GIS environment. These foundations and means allow us to reconstruct the development of the river Tiber's historical course in antiquity and its impact on specific organizational aspects of Rome's port system. In this sense, this study provides new insights and avenues of research (applicable to other geographical areas and periods of time) to evaluate the system's changing capacity for transport and the potential existence of a signalling system, in contrast to previous hypotheses on the organization of river traffic along the Tiber.
