 The Adria channel survived the Gauls period and was still there when the Romans arrived.In the first century AD, Pliny the Elder however does not write of this Adria river; the Adige overflowed into the Tartaro-Philistina and caused a flood in the area that returned to wetlands.The port of Adria was still working thanks to the "fossiones" and the other canals, still maintained by the Romans.
