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.
A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot transport away the supplied sediment.Despite a popular legend, this use of the word delta was not coined by Herodotus.n rare cases the river delta is located inside a large valley and is called an inverted river delta. Sometimes a river divides into multiple branches in an inland area, only to rejoin and continue to the sea. Such an area is called an inland delta, and often occurs on former lake beds.
