Conectividad y movilidad en la Bahía de Cádiz durante laantigüedad a través de los sistemas de informacion geográca:una propuesta metodológica

Resumen

The Bay of Cadiz has historically been characterised as a very dynamic socio-natural space. The current landscape is the result of a series of natural phenomena such as erosion, sedimentation and the influence of the tides, to which must be added intense anthropic action. For the High Imperial Roman period, mobility in this area must have been complex, as there are several elements to take into account: several areas of intertidal influence, where rivers and tidal channels converge, as well as the configuration of the coastline up to the city of Gades, elements that were very sensitive to anthropic modifications such as the construction of the main Roman roads and the aqueduct that supplied water to the city. This configuration makes the space comprising the Bay of Cadiz ideal for testing, through the use of Geographic Information Systems (GIS), the potential mobility that would have taken place in ancient times. To this end, this article reconstructs the palaeoenvironment of Cadiz through the creation of a Digital Terrain Model (DTM), defining the different conditions of mobility for a given case, and assigning different forms of mobility (terrestrial, fluvial, intertidal and maritime). Finally, the articulation of this space is discussed, using a “Model of Accumulation of Optimal Displacements from an Origin” (MADO).
