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:
“My favorite figure of the American author is that of a man who breeds a favorite dog, which he throws into the Mississippi River for the pleasure of making a splash. The river does not splash, but it drowns the dog.”
—Henry Brooks Adams (1838–1918)
