A "Delta", so-called because of the tendency of the 'channels' created by hydrologic soil deposition to frequently vary their courses due to creation of impedences to linear flow caused by precipitation of the colloidally-suspended particles of soil which fall out of suspension as the velocity of the water is reduced, raising the floor of the channels, thus forcing the flow to seek an easier [more lateral] route. "Delta" is used in a mathematical sense, meaning "variation".
Soil Erosion affects the land in many ways. It can take away the topsoil of the soil horizon which is important to growing crops and pasture for its organic matter. Also erosion can cause leaching of the soil which means that nutrients leave the soil and may become hazardous to aquatic life downstream.
It affects through it changes the shape of the land.....by the caused of wind and water that carried tiny particles of soil and rocks away.....
Soil erosion benefits areas downstream of where the soil washed away by giving them good soil. For years it helped areas along the Nile River. Studies recently shows that It also puts carbon in the wetlands downstream which slows global warming.
Both, the erosion of soil can be carried out naturally in storms. It can also be caused to occur by impropper farming techniques and by inappropiate land use.
soil flow
A delta.
The land area that includes soil carried downstream by a river and deposited at the rivers mouth is called a delta. The delta is also where the river enters the ocean or lake.

Deltas are areas of rich soil located at the mouths of many rivers. As rivers move downstream, they pick up soil from the river banks, later depositing it at the delta.
In many cases, a delta forms where a river meets the sea. Soil carried downstream by the river is deposited at its mouth. Over time, new land forms as the soil builds up. Well-known examples of river deltas are the mouths of the Nile River in Egypt and the Mississippi River in the USA.

the currents push it downstream
