It is called SILT.
This is called a river delta.
A delta.

A delta is formed.
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.
Most of it is trapped at the dam at Lake Nasser. After that it would be deposited when the flow of the river is too slow to carry it and ultimately what is left is deposited in the delta.
A delta is a landform that is most likely made by the process of depositing sediments. Deltas are formed at the mouth of a river where the river's sediments are deposited as the river slows down and enters a larger body of water, such as a lake or an ocean. The accumulation of sediments over time creates a triangular-shaped landform with various channels and distributaries.
Silt becomes built up at the mouth of rivers as it is deposited into larger bodies of water. Silt is composed of mineral rich soil which is excellent for crops.
When the river hits the sea and slows down, hence why a large number of rivers have sedimentary deltas at the mouth
The Delta
A delta is formed.
They are deposited at the river mouth, before it finally empties its water into the ocean.
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.
sediments are transported by ocean rift, streams, river currents, wind (air). they are deposited according to size. The largest sediments are deposited first. The sediments settle into the sand and are carried by the stream. Near the mouth of the stream where the water moves slowly the small sediments settle out. The larger sediments get carried by the river into the sea then the samller sediments. The sea water dissolved minerals and soak the sediments and cement together. This eventually forms sediments.
Deposition is the state of being deposited or precipitated as in the deposition of soil at the mouth of a river.
Most of it is trapped at the dam at Lake Nasser. After that it would be deposited when the flow of the river is too slow to carry it and ultimately what is left is deposited in the delta.
a Delta is a 'wetland' form that is created in the mouth of a river and is formed by sediments carried down by the river and deposited in its mouth. Over millions of years this can form a large flat area, or a tidal mouth, which is covered by the tidal flow of the sea
The earth and sand deposited there are called "sediments" and they build up to form what is called a "delta"; a triangular wedge shaped like the Ancient Greek letter "D" - hence "delta".
The mud deposits of deltas come from the erosion and transport of sediments from upstream sources by rivers. These sediments are carried by the river and eventually deposited at the river mouth where the flow velocity decreases, forming the characteristic delta landforms.
