An alluvial channel is a watercourse that is formed by the flow of a stream or river and contains sediment (alluvium) that has been formed by erosion and deposited along its bed and banks. These channels are typically found in floodplains and are dynamic in nature, shifting their course over time in response to changes in water flow and sediment transport.
Alluvial is a descriptive term referring to sediments deposited along a fan-shaped area by a river or stream. Thus, a rock or mineral could be described as being alluvial in that it was placed in its current location by alluvial deposition. Alluvial is not a rock type.
Another name for alluvial soil is fluvisols.
Factors that increase the likelihood of alluvial deposition include high sediment load carried by rivers, a decrease in water velocity due to a decrease in slope or flow rate, vegetation slowing down the flow of water, and the presence of large obstacles or obstacles in the river channel that disrupt the flow.

Alluvial soil can vary in color depending on the minerals present in the region where it is found. Common colors of alluvial soil include brown, gray, red, or yellow. These colors are a result of the composition of the soil, such as the presence of iron or organic matter.
This is water erosion that does not flow in a channel

Water flowing downhill in a large channel is called a River. Deposition creates landforms such as alluvial fans and deltas. It can also add soil to a river's fllod plain.

The River Severn does not have an alluvial fan. Rivers that empty into estuaries do not have alluvial fans.

Alluvial sediments are those deposited by a river.
A well that is drilled into an alluvial deposit, which is sediment from a river or lake.

Alluvial gold is found in alluvium, which is the soil in and around rivers. Alluvial gold is often found through river flats and floodplains.
