Yazoo stream

A Yazoo stream is a geologic and hydrologic term for any tributary stream that runs parallel to, and within the floodplain of a larger river for considerable distance, before eventually joining it. This is especially the characteristic when such a stream is forced to flow along the base of the main river's natural levee. Where the two meet is known as a 'belated' confluence or a 'deferred' junction. The name is derived from a now vanished Native American tribe, the Yazoo Indians. The Choctaw word is translated to "River of Death" because of the strong flows under its bank full stage.
