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:
““I’ll love you dear, I’ll love you
Till China and Africa meet,
And the river jumps over the mountain
And the salmon sing in the street.”
