Want this question answered?
IN Mesopotamia floods would destroy and kill but left silt behind but in Egypt they were predicidable and were used to only leave rich soil behind.
The timing of the floods would determine when the crops would need to be harvested and how effectively they could be irrigated. If the flood was too powerful, it could easily wipe away the crops and leave the cities starving. On the other hand, the floods deposited silt filled with nutrients for the growing plants and helped the water table to rise to a point where grains could grow effectively.
The fine soil that was deposited at the mouth of a river in Egypt was called silt.
The flooding in Mesopotamia brings silt which blends in with the soil, making it rich and good for farming.
The two rivers of Mespotamia (The Tigris and The Eupharates rivers) supported early civilization because the rivers ran right through Mesopotamia they brought silt. (Silt is fertile and goood farmland.) Since there was silt, it was easier to farm which made alot of food surplus. Since there was so much food, people came to Mespotamia and then it kept growing.
Many farming areas in the world depend on silt deposited during floods to replenish the fertility in their soil. RB
Flat land near the edges of rivers formed by mud and silt deposited by floods is called a delta. There are several deltas around the world.

Silt and soil are most deposited in the water and then it goes in to the rivers or oceans :)
When the floods went down it left thick rich mud (black silt) which was excellent soil to plant in.Silt deposited by annual floods along the Nile River created the rich and fertile soil that could be cultivated.
Loess is deposited by wind.
A flood plain is a flat land bordering a river made up of alluvium (clay, sand and silt) deposited during floods. When a river overflows, the floodplain is covered with water. Hope this helps :)
That would be called silt. Are you studying ancient Mesopotamia or Egypt, by any chance?

the answer is silt
The soil that is deposited is called silt. The landform that is often created by deposited silt at the mouth of a river is called a river delta.
It is a fine-grained unstratified accumulation of clay and silt deposited by the wind
