River channels are the natural pathways through which rivers flow, shaped by the movement of water and sediment over time. They can vary in width, depth, and shape, influenced by factors such as terrain, water volume, and sediment characteristics. River channels are crucial for water transport, ecosystem health, and influencing surrounding landscapes. They can also change due to erosion, sediment deposition, and human activities.
River bifurcation is the name for where a river splits into several channels with islands in the middle. Distributaries are the product of river bifurcation which can form islands and channels.
Some names of water channels in Asia include the Yangtze River in China, the Ganges River in India, the Mekong River in Southeast Asia, and the Indus River in Pakistan.
by erosion eroding the banks and beds of a river
Lyne River in England, Li River in China and Lachlan River in Australia are famous water channels. They begin with the letter L.

The Congo River features a complex network of channels, primarily consisting of the main river channel and numerous tributaries, tributary channels, and smaller streams. The river's main channel is characterized by deep, navigable waters, while its banks are flanked by a series of islands, sandbanks, and backwaters. The river's channels vary in width and depth, influenced by seasonal flooding and geological formations. This intricate system supports diverse ecosystems and is crucial for local transportation and fisheries.
yellowstone river or Cascadia river
The first visible effect of water erosion on a river is typically the formation of small channels or rills on the river banks. As water flows, it gradually erodes the soil and sediment, creating these initial channels. Over time, these channels can deepen and widen, leading to significant changes in the river's morphology.

The answer is distributaries
A palaeodrainage is a system of drainage channels cut by an ancient river.
The channels are clearly marked on Admiralty charts.
