Sediment deposited where a river flows into an ocean or lake is a delta.

A delta is a triangle shaped low landform that forms from deposition of sediment transported by a river as the flow leaves its mouth and enters a water body (such as an ocean, lake or a reservoir) that cannot transport the released sediment. Delta formation is based on certain factors including the location, size and geometry of the receiving basin.
