A river mouth or stream mouth is a part of a stream where it flows into another stream, river, lake, reservoir, sea, or ocean. At the mouth of a river a delta can form causing sediment pileup. A river can flow into a lake, sea or into an ocean. 1  Confluence. 2  River delta. 3  Estuary. 4  Liman.
Often at the mouth, a delta forms. A delta is a landform that forms at the mouth of a river because the river carries sediment along with the water as the river flows through its banks. The river water deposits this sediment together when it flows into the larger body of water and forms land. A delta is often shaped like a triangle.
