Satellite images display extreme Mississippi River flooding from space

16.05.2011
Recent Landsat satellite data captured by the USGS and NASA on May 10 shows the major flooding of the Mississippi River around Memphis, Tenn. and along the state borders of Tennessee, Kentucky, Missouri, and Arkansas as seen from 438 miles above the Earth.

The flood crest of 47.87 feet on May 10, is the second highest rise in recent history; the highest being 48.7 feet in 1937. Five counties surrounding Memphis have been declared disaster areas, and the costs of the flooding are expected to approach $1 billion. The Mississippi River crest continues to move south and is expected to occur in the Greenville, Miss. Area around May 16 to finally crest in New Orleans around May 23.

When natural hazards like flooding occur, USGS provides the most recent Landsat data to local emergency managers.

"Landsat imagery is crucial in helping to monitor the flood rate and effects of the flooding in the region, and to aid in the decision making process regarding flood control. Decisions such as closing portions of the Mississippi River to shipping and opening flood gates outside of low-lying New Orleans in preparation to the flood wave as it makes its way slowly down the river to the Gulf of Mexico," said Mark Anderson, Acting Director of the USGS Earth Resources Observation and Science Center.

James Irons, Landsat Data Continuity Mission (LDCM) Project Scientist at NASA Goddard Space Flight Center in Greenbelt, Md. said, "NASA Goddard has managed the development of all the successfully launched Landsat satellites and is currently developing the next Landsat satellite system, the Landsat Data Continuity Mission, in partnership with USGS." The launch of LDCM is scheduled for December, 2012.

Remotely sensed data are not the only science endeavors occurring due to floods. The USGS collects river data through its network of about 7,700 stream gauges around the Nation. You can receive instant, customized updates about water conditions, including flooding, by subscribing to USGS WaterAlert (› http://water.usgs.gov/wateralert).

General flood information is available at USGS Science Features () and USGS Flood Information (› http://water.usgs.gov/osw/floods/).

The scenes captured by Landsat 5 show the Mississippi River in the Memphis, Tenn. area, and along the state borders of Tennessee, Kentucky, Missouri, and Arkansas. The January images show the river before it began to flood. In the May images, the dark blue tones are water, the light green is cleared fields, and the light tones are clouds.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
