A deposit at the opening of a river is called delta.
An alluvial fan starts at just a build up of sediment at the mouth of a river. As the current moves, more and more sediment is lifted into the stream and carried until it hits a sediment deposit. As the sediment deposit gets bigger, it is exposed to the air and forms a sediment mountain. As the mountain gets bigger it forms an island in the middle of the mouth of a river. This is called an alluvial fan! Hope this was helpful!
