 After the Malopera breach in 1438 the Tartaro overflowed and new embankments were built, roughly following the previous natural course; this part of the river has been known by the name of Canalbianco since the canalization of its stream.The "Porto Viro cut-off" in 1604 diverted the Po river before the confluence of the Tartaro-Canalbianco; since then the former channel of the Po delta named "Po di Levante" has been the final part of the river.Currently it flows by the modern Adria; it communicates, by canals, with the Po river and the Adige river.
