sand dunes i think?
Yes, when the flow of a river slows the sediment is deposited.
The flow of water slows enough for the silt to be deposited.
The flow rate of the river slows precipitously at the mouth of the river, and any carried silt drops to the bottom - where it builds up to form a delta.

As a river flow slows, the sediment starts to settle out. The water at the river's edge often has the lowest flow or movement so there will be more sedimentation.
it slows the streams flow
The flow of water slows enough for the silt to be deposited.
A stream deposition occurs when, in the lower reaches, the flow of water (speed of flow) is reduced. Which is when the heavier sediment falls out and settles on the river bed.
A delta. The sediment settles there because of the slowing of the river, causing gravity to overpower the momentum of the flow of water.
