Prospections géophysiques multi-méthodes de structures portuaires antiques à Narbonne (Aude, France)

Abstract : Since 2005, an interdisciplinary team of research attempts to reconstruct the topography of the ancient port of Narbonne, considered one of the largest ports in the Roman Empire. Begun in 2007, geophysical surveys are one of the pillars of this work. They have evolved over the measurement campaigns in order to adapt to the constraints of the field, the evolution of the results and the emergence of new problems. The major structures of the site Le Castélou / Mandirac, identified as fitted mouth of a southern arm of the Aude, were located then confirmed by the excavation. Two parallel jetties constructed in wetland on a length of more than 1.5km border the 50m-wide channel (4m-depth). With a width of 15m to 25m, they are converted into road at the end of the first century by the contribution of considerable amounts of materials and thousands of wooden piles that reinforce their banks. Traces of port activities are numerous. Nowhere in the Roman world, works of this extent to channel a river have been uncovered. They emphasize the desire to control a fluctuating environment to ensure stability and sustainability of this place of exchange, finally abandoned in the late fifth century.
