Common terms to name individual river distributaries in English-speaking countries are arm and channel.These terms may refer to a distributary that does not rejoin the channel from which it has branched (e.g., the North, Middle, and South Arms of the Fraser River, or the West Channel of the Mackenzie River), or to one that does (e.g. Annacis Channel and Annieville Channel of the Fraser River ...
The number of distributaries that are present is in part determined by the rate of sediment discharge, [6] and increased sediment discharge leads to more river bifurcation. This then leads to increased numbers of distributaries in deltas. Delta bifurcation has a typical angle at which it is observed, with a critical angle of approximately 72º. [7]
A river delta is so named because the shape of the Nile Delta approximates the triangular uppercase Greek letter delta.The triangular shape of the Nile Delta was known to audiences of classical Athenian drama; the tragedy Prometheus Bound by Aeschylus refers to it as the "triangular Nilotic land", though not as a "delta".

The cuspate deltaic lobe is defined by its abrupt rate of discharge from river to body of water, and the creation of multiple cusp systems built up into separate but active distributaries. [9] One such example of a cuspate delta is the Tiber River delta of Italy. The river was formed first as a deltaic lobe cusp prograded from the river mouth.
It flows for 1,465 km (910 mi), first eastwards across the Deccan Plateau then turns southeast, entering the Eluru district and Alluri Sitharama Raju district of Andhra Pradesh, until it splits into two distributaries that widen into a large river delta at Dhavaleshwaram Barrage in Rajamahendravaram and then flows into the Bay of Bengal.

The delta is fan-shaped, formed by the Orinoco River as it splits into numerous distributaries, called caños, which meander through the delta on their way to the sea.The main distributary is called the Rio Grande, which empties south-southeast through the southern portion of the delta, and the second major distributary is Caño Manamo, which runs northward along the western edge of the delta.
