upright= 1.25 |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.Robert L Bates, Julia A Jackson, ed. Dictionary of Geological Terms: Third Edition, p. 568, American Geological Institute (1984). Where the two meet is known as a "belated confluence" or a "deferred junction". The name is derived from an exterminated 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. Examples  Montana and Jordan Creeks Moesian stream/flow is a parallel derivative remnant of paleoriver. Many Yazoo streams are actually paleo-remnants of just one original river. The good examples of moesian flow are Mossy Creek, Missouri and Jezava, Morava. Cosmo, Lepota L. (2019). Interoceanic Waterways Network System, Integrated Systems: Hydrology of the Future.

Over time, the main river flows through the landscape, widening a valley and creating a floodplain. Sediment accumulates and creates a natural levee. Tributaries that want to enter the main channel are not allowed because of this levee. Instead, the water then enters the back swamps, or form a yazoo stream. Because yazoo streams are separated from the main river by natural levees, they flow and meander (streams and rivers rarely flow in straight lines) parallel to the main stream channel or river on the floodplain for a considerable distance. These series of smooth bends or curves flows with a slight gradient, and is normally blocked from entering by a natural levee along the larger stream. A yazoo stream will join the major river where it will eventually break through the natural levees and flow into the larger waterway at its belated confluence.  Glaciers Mendenhall Glacier Yazoo stream formation can also be influenced by glacial processes. An example is the formation of the Montana Creek valley during the recent Little Ice Age. The Mendenhall Glacier carved out a wide floodplain that is domed in the center. High valley walls due to tectonic uplift and glacial outwash (the natural levee) create two yazoo streams that parallel the Mendenhall River.
