Nederrijn ("Nether Rhine") is the name of the Dutch part of River Rhine from the confluence of the cut-off Rhine bend of Oude Rijn and the Pannerdens Kanaal (which was dug to form the new connection between the Waal and Nederrijn branches). The city of Arnhem lies on the right (north) bank of river Nederrijn, just past the branching-off of River IJssel. River Nederrijn flows on to the city of Wijk bij Duurstede, from where it continues as River Lek. The once-important but now small branch of Kromme Rijn (in Roman times border river of the Roman Empire) carries the name "Rhine" towards the city of Utrecht.
