A delta is formed.
The sediment itself is called silt, and it often is deposited at the mouth of rivers and forms a landform called a river delta.
The greater the speed the less sediment deposited. A delta is where a river slows way down and sediment is deposited at the mouth of the river.
A delta is formed.
A delta is a body of sediment deposited at the mouth of a river or stream where it enters an ocean or lake.
Rivers carry sediment, which when deposited at the beach, increases the land. Similarly, rivers can carry sediment away from a beach, also changing its shape. These two forces can work together to effectively move sediment from one area of the beach to another. Similarly, storms also move sediment.

Delta
soil flow
The river runs however long, all the while picking up sediment, sand, rocks, etc. and continue doing this for the river's length, and at the very end of the river (mouth), all of this sediment is deposited, leaivng sand at the river mouth.
Deposition is the state of being deposited or precipitated as in the deposition of soil at the mouth of a river.
