It is the river bank. Or coast, if it is emptying into the ocean, like the Mississippi River.

The Amazon river meets the Pacific ocean. The place where the river meets the ocean is the tributary. The Amazon tributary is gigantic.Let's follow the left tributary to it's source.I'm not sure of the name of the Amazon River's largest tributary.
Deltas form where rivers meet the ocean because the river's sediment load slows down and settles due to the decrease in water velocity caused by the ocean's tidal movements and waves. This accumulation of sediment creates landforms with various distributary channels that fan out like the Greek letter delta, giving rise to the name.
