Sediments high on alluvial fans are rich in gravel with cobble- and boulder-sized rock fagments
Deltas; alluvial fans.
The braided markings on alluvial fans are from erosion caused by braided streams. It is created by the meandering, combining, and separating of the waters as they flow over and around different landforms.
Alluvial fans are triangular deposits of sediment called alluvium. These fans occur when fast-moving water is released from the confines of a river or stream bank and then flows over a wider plain.
Alluvial fans are when a river slows and deposits sediment on a flatter plain. This would be caused by eroson.

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.
A bajada is an alluvial plain formed at the base of a mountain by the coalescing of several alluvial fans.
