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.[1] Where the two meet is known as a 'belated' confluence or a 'deferred' junction. The name comes from the Yazoo River, which runs parallel to the Mississippi River for 280 km (170 mi) before converging,[2] being constrained from doing so upstream by the river's natural and man-made levees.
