It's the flow of water that carries solids, whenever the flow slows then some of the solids will fall to the bottom of the stream.
In areas where their speed and ability to transport material is reduced. The final destination for most sediments is a basin, lake, or ocean.

· Alluvial fans develop where streams issue from canyons onto adjacent valley floors and deposit sediments derived through the erosion of rocks upstream.
· Alluvial fans develop where streams issue from canyons onto adjacent valley floors and deposit sediments derived through the erosion of rocks upstream.
Alluvial fans are formed when sediments carried by rivers or streams are deposited as the water flow slows down upon reaching flatter terrain. The sediments pile up in a fan-shaped deposit due to gravity pulling them downhill, creating a characteristic triangular landform. This process is typically seen in arid regions with high sediment loads and steep mountain slopes.

An alluvial fan is a fan-shaped deposit that is created when a fast flowing river slows down. Alluvial fans develop where streams issue from canyons onto adjacent valley floors and deposit sediments derived through the erosion of rocks upstream.
The main agent of deposition is water, specifically rivers, streams, and oceans. These bodies of water transport sediments and deposit them when their energy levels decrease, leading to the formation of sedimentary rocks.
a glacial deposit that is sorted and layered by streams or melted water is called
Alluvial soils are formed by the deposition of sediments carried by rivers and streams. Since these sediments are typically deposited by rivers, alluvial soils are also referred to as riverine soils. They are known for their fertility and are found in areas where rivers deposit sediments during floods or over time.
Alluvial deposits refer to sediments deposited by streams. These deposits are typically composed of sand, gravel, and silt that are carried and deposited by flowing water.
