Alluvial channel
WebPalaeochannel. In geology, a palaeochannel, palaeovalley, or palaeoriver (US spellings paleo-) is the remnant of an inactive river or stream channel that has been filled or buried by younger sediment. The sediments that the ancient channel is cut into or buried by can be unconsolidated, semi-consolidated, consolidated or lithified. WebThe three main channel patterns in alluvial plains are: braided, meandering and straight. Channels on an alluvial fan show a braided pattern, and their depth is shallow. The river bed is composed of gravelly deposits. Channels in a flood plain meander and have a river bed composed of sand.

WebA bedrock river is a river that has little to no alluvium mantling the bedrock over which it flows. However, most bedrock rivers are not pure forms; they are a combination of a bedrock channel and an alluvial channel.

WebAlluvial landforms in meandering channels extend downstream from the point of maximum curvature of the meander belt. Meandering channel paystreaks, which follow the courses of lag gravels in successive migrating meander, may be reworked during intermittent pulses of uplift and erosion produced by minor crustal adjustments.
