The Cave's Archive of Missouri River Flooding 2011 Daily Updates: 2011 Missouri River Flooding Update

Flood Information Terminology

100 year flood -- A level of flood water that occurs every 100 years on average. This can be more accurately described as flood conditions that have a 1 percent probability of being met or exceeded each year.

500 year flood -- Flooding with an annual probability of 0.2 percent that conditions would be met or exceeded.

Berm -- A raised barrier or shelf separating two areas. Often built to control erosion by slowing or directing surface runoff.

CFS (Cubic feet per second) -- The measurement used to describe the the amount of water flowing through a river or released by a dam. A cubic foot has the volume of a cube with sides of one foot in length.

For example, an Olympic-size swimming pool holds about 88,000 cubic feet of water. The highest release expected for this flood is 150,000 cubic feet per second from Gavins Point Dam, near Yankton, S.D.

Dewater -- The process of removing groundwater or surface water, usually by pumping.

Intentional breach -- The U.S. Army Corps of Engineers sometimes breaches levees to relieve flooding upriver, including to relieve pressure on floodwalls or other structures protecting critical land.

Levee (or dike) -- A constructed slope or wall to keep floodwaters from an inundation area or adjacent land. Can be permanent or temporary and made of earth, concrete or other materials.

Pooling -- As the water table rises with flooding, water can collect in low areas, including near levee bases. Water from pooling is not considered seepage, because it's from the water table or rainwater, rather than a leak through a levee.

Piping -- Erosion along the base of a levee from strong river currents. This can cause failure as the levee foundation deteriorates too far and its structure collapses.

Riprap -- Rock or concrete rubble often placed on shorelines and bridge abutments to prevent erosion from water and ice.

Sand boil -- Sand boils form on levees when water pressing down on the river side pushes water through to the dry side. Not all sand boils are the same:

Carlos Lazo, a spokesman for the U.S. Army Corps of Engineers, said boils leaking clear water are generally routine fixes. However, he said dark water coming from boils indicates sediment erosion and is more serious.

Scour hole: A hollow in the bed of a stream caused by the erosive action of rapidly circulating flow.

Seepage -- Water that travels through or under a levee. Some seepage is considered normal or expected, but too much can indicate big problems within a levee, and lead to breaking.

Omaha Public Power District (OPPD): If you look closely in the photos, our plant, our substation and other buildings are dry behind berms, sandbag walls and AquaDams. The plant is secure from water to the 1,014 feet above sea level elevation (the river is now at 1,006). It also has diesel generators and additional fuel staged to provide power from on site...(read more)

Nebraska Public Power District (NPPD): There have been at least five situations of flooding around the Brownville area since 1952, and Cooper Nuclear Station, which has experienced several floods since it began commercial operation in 1974, was built to withstand various natural disasters, including tornadoes and earthquakes. The site was elevated 13 feet above the natural grade to 903 feet sea level elevation to accommodate the maximum, probable flooding event. (Earlier this week floodwaters came within 18 inches of 902 feet -- the mark at which Cooper would be shut down.)... (read more)

Fort Calhoun nuclear power plant 20 miles south of Omaha gets safety downgrade

Posted: Tuesday, September 6, 2011 3:47 pm
In its latest review by the Nuclear Regulatory Commission, the Fort Calhoun Nuclear Station's performance was downgraded a notch and plans are in place for more inspection and oversight.

On the basis of two violations, the NRC placed the Fort Calhoun plant in the "Multiple/Repetitive Degraded Cornerstone Column," the second worst of five columns on its complicated Reactor Oversight Process Action Matrix. The only column lower is "unacceptable" and plants in that category are not allowed to operate.

Army Corps of Engineers predicts the Missouri River will return to normal levels in Nebraska, Iowa and Missouri sometime in October

AP OMAHA - September 7, 2011 — The Army Corps of Engineers predicts the Missouri River will return to normal levels in Nebraska, Iowa and Missouri sometime in October, and put an end to flooding that began in June.

The Corps' Jody Farhat said Tuesday the plan to gradually reduce the amount of water released into the river has been going well so far.

The Corps already cut the amount released from Gavins Point Dam in South Dakota from 160,000 to 90,000 cubic feet per second. Officials will wait until Sept. 16 to resume reductions, so there's time to check levees and make sure they're stable.

The Corps estimates that 37.5 million acre feet of water flowed down the Missouri River from May to August. That's significantly more than the normal runoff of 24.8 million acre feet.
