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. Mendenhall Glacier [13] 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.
Utilize either kinematic wave or full dynamic wave flow routing methods. Model various flow regimes, such as backwater, surcharging, reverse flow, and surface ponding. apply user-defined dynamic control rules to simulate the operation of pumps, orifice openings, and weir crest levels. Percolation of infiltrated water into groundwater layers.
The Yazoo Backwater Area in the Mississippi Delta north of Vicksburg, Mississippi, experienced both record flood stages and record duration of flooding during the winter, spring, and summer of 2019. Portions of Warren, Issaquena, Sharkey, Yazoo, Humphreys, and Washington Counties were flooded. Almost half of the land area of Issaquena and ...
On May 3, using the planned procedures for the Birds Point-New Madrid Floodway, the Corps of Engineers blasted a two-mile (3 km) hole in the levee protecting the floodway, flooding 130,000 acres (530 km 2) of farmland in Mississippi County, Missouri, in an effort to save the town of Cairo, Illinois and the rest of the levee system, from record-breaking flood waters.

Mississippi River at Kaskaskia, Illinois, during the Great Flood of 1993. A 100-year flood is a flood event that has on average a 1 in 100 chance (1% probability) of being equaled or exceeded in any given year.
In response, the United States Congress ordered the MR&T to review of the flood control plan. Maximum flows were changed to 2,600,000 cubic feet per second (74,000 m 3 /s) at Cairo, 3,065,000 cubic feet per second (86,800 m 3 /s) at Arkansas City with the White River backwater area levee overtopped, and Red River Landing unchanged at 3,000,000 ...
