Pannerdens Kanaal in the context of "Betuwe"

The Rhine–Meuse–Scheldt delta is a river delta in the Netherlands formed by the confluence of the Rhine, the Meuse (Dutch: Maas) and the Scheldt rivers. In some cases, the Scheldt delta is considered a separate delta to the Rhine–Meuse delta. The result is a multitude of islands, branches and branch names, in which a waterway that appears to be one continuous stream may have numerous separate names for different sections, e.g. Rhine → Bijlands Kanaal → Pannerdens Kanaal → Nederrijn → Lek → Nieuwe Maas → Het Scheur → Nieuwe Waterweg. Since the Rhine contributes most of the water, the term "Rhine Delta" is commonly used, although this name is also used for the delta where the Alpine Rhine flows into Lake Constance. By some calculations, the Rhine–Meuse–Scheldt delta covers 25,347 km (9,787 sq mi), making it the largest in Europe.

The Rhine–Meuse–Scheldt delta is economically extremely important, since the three rivers are major navigable waterways. The delta is the entrance from the North Sea to the German and Central European hinterland (and to a lesser extent France). Major ports in the delta are Rotterdam, Antwerp (Belgium), Vlissingen, Amsterdam (through the Amsterdam–Rhine Canal), and Ghent (through the Ghent–Terneuzen Canal). The land areas in the delta are protected from flooding by the Dutch Delta Works.

Lower Rhine (German: Niederrhein, pronounced [ˈniːdɐˌʁaɪn] ; kilometres 660 to 1,033 of the Rhine) is the section of the Rhine between Bonn in Germany and the North Sea at Hook of Holland in the Netherlands, including the Nederrijn (English: Nether Rhine) within the Rhine–Meuse–Scheldt delta; alternatively, Lower Rhine may also refer to just the part upstream of Pannerdens Kop (km 660–865.5), excluding the Nederrijn.

It is the last of the four sections of the Rhine between Lake Constance and the North Sea (the others being the High Rhine, Upper Rhine and Middle Rhine).

The Nederrijn (Dutch pronunciation: [ˈneːdəˌrɛin]; "Lower Rhine"; distinct from the Lower Rhine or Niederrhein further upstream) is the Dutch part of the Rhine from the confluence at the town of Angeren of the cut-off Rhine bend of Oude Rijn (Gelderland) 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 the Nederrijn, just past the point where the IJssel branches off. The Nederrijn flows on to the city of Wijk bij Duurstede, from where it continues as the Lek. The once-important but now small Kromme Rijn branch (in Roman times part of the Limes Germanicus and border river of the Roman Empire) carries the name "Rhine" towards the city of Utrecht.

From the city of Utrecht, the Kromme Rijn forks into the Vecht to the north, and into the Oude Rijn (Utrecht and South Holland) to the west. The first part is channelised and known as the Leidse Rijn (Leiden Rhine). After the railway bridge near Harmelen (municipality Woerden) it is known as the Oude Rijn, flowing westward to the North Sea.
