It is called a delta
Contrary to your question, it is formed by deposition. When a river reaches a lake or the sea, water slows down and loses the power to carry sediment . The sediment is dropped at the mouth of the river, and sediment builds up in layers, forming a delta.
As a river flows it picks up sediment and carries it away. When the river reaches the ocean the sediments deposited, over time a delta forms.
Sediment will settle when the river current carrying it along reaches an area of calmness. This may result in sandbars or muddy river banks. It is also likely to settle when carried out to sea and it contributes to the ooze on the ocean floor.
When it rains on a mountain top, it creates a river. That river flows down carrying sediments witch end up in the beach.
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.
Due to the sediment within the river. this sediment causes the river to appear orange/reddish
by building up in one place for example, a river along a street flows carrying sediment and sometimes there are rocks that are placed at the end of the river. the rocks stop the river at that one point and all the sediment rushing through builds up over time in one place.
