Abstract


Topographic changes have been significant in the city of Cartagena and its surroundings along history. The city that Polybius described in II century B.C. has spread northward, occupying the old Almarjal, now desiccated by the diversion of the wadis that flooded it. The palaeotopography of the city has been documented and analyzed from the lithology of 377 geotechnical drillings and other 20 new continuous drilling within the framework of the Project "Surveying and planning of a privileged Mediterranean city, Arqueotopos I and II". Digital terrain models (DTM) of the layers of interest, consisting of anthropic fills and sediments, have been generated. Thickness of each layer has been studied by drawing longitudinal profiles. Finally, a three-dimensional virtual reconstruction has been made to show graphically the documented changes in each layer, to serve both research and divulgation of knowledge.
