A river delta is a landform that is formed at the mouth of a river, where the river flows into an ocean, sea, estuary, lake, or reservoir. Deltas are formed from the deposition of the sediment carried by the river as the flow leaves the mouth of the river. Over long periods of time, this deposition builds the characteristic geographic pattern of a river delta.
Contrary to popular belief, this usage of the word delta was not coined by Herodotus.

Famous quotes containing the word river:
“In order to get to East Russet you take the Vermont Central as far as Twitchell’s Falls and change there for Torpid River Junction, where a spur line takes you right into Gormley. At Gormley you are met by a buckboard which takes you back to Torpid River Junction again.”
—Robert Benchley (1889–1945)
