Southampton scientists along with colleagues in New Zealand have used a sophisticated optical mapping technique to identify and accurately measure changes in coastal morphology following a catastrophic series of landslides. "Our findings are important for assessing geological hazards and reducing the dangers to human settlements," said geophysicist Professor Jon Bull of the University of Southampton's School of Ocean and Earth Science based at the National Oceanography Centre, Southampton,...

Researchers from North Carolina State University have developed a sensor that allows engineers to assess the scour potential of soils at various depths and on-site for the first time "“ a technology that will help evaluate the safety of civil infrastructure before and after storm events. Scour, or erosion of soil around structures due to water flow, is responsible for a wide range of critical infrastructure failures "“ from unstable bridges to the levees that gave way in the wake...

Alterations lead to ecological degradation The amount of water flowing in streams and rivers has been significantly altered in nearly 90 percent of waters that were assessed in a new nationwide USGS study. Flow alterations are a primary contributor to degraded river ecosystems and loss of native species. "This USGS assessment provides the most geographically extensive analysis to date of stream flow alteration," said Bill Werkheiser, USGS Associate Director for Water. "Findings show the...

Researchers say soil in southern Oregon forest remains threatened by practices used a half century ago Clear-cut logging and related road-building in the 1950s and 1960s in southern Oregon's Siskiyou Mountains disrupted soil stability and led to unprecedented soil erosion made worse during heavy rainstorms, report University of Oregon researchers. While logging practices have improved dramatically since then, the damaged landscape -- the removal of low vegetation that helps to protect...

WASHINGTON, Sept. 20 /PRNewswire-USNewswire/ -- Snow melt in the Colorado River basin is occurring earlier, reducing runoff and the amount of crucial water available downstream. A new study shows this is due to increased dust caused by human activities in the region during the past 150 years.

NASA and European researchers have conducted a novel study to simultaneously measure, for the first time, trends in how water is transported across Earth's surface and how the solid Earth responds to the retreat of glaciers following the last major Ice Age, including the shifting of Earth's center of mass. To calculate the changes, scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif.; Delft University of Technology, Delft, Netherlands; and the Netherlands Institute for Space...

Permafrost warming continues throughout a wide swath of the Northern Hemisphere, according to a team of scientists assembled during the recent International Polar Year. Their extensive findings, published in the April-June 2010 edition of Permafrost and Periglacial Processes, describe the thermal state of high-latitude permafrost during the International Polar Year, 2007-2009. Vladimir Romanovsky, a professor with the snow, ice and permafrost group at the University of Alaska Fairbanks...

Using a flood simulator, MU researchers reveal cottonwood trees as a profitable crop in devastated flood areas When the Missouri River flooded in 1993 and 1995, it left a deep layer of sandy silt that covered thousands of acres of rich farmland. Now, MU forestry researchers may have found a crop that can survive a flood and act as a sustainable source of biomass. During the 1993 flood, Gene Garrett, forestry professor and former director of the Center for Agroforestry, observed that...

Desert greening
2013-04-25 16:10:03

Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...

Theodore Roosevelt National Park

Theodore Roosevelt National Park is located in western North Dakota in the United States. The park contains 70,446 acres of land that is separated into three distinct badland areas known as the Elkhorn Ranch Unit, the South Unit, and the North Unit. Roosevelt  first visited the area in 1883, while hunting for bison, and is said to have “fallen in love” with the badlands. After investing a large sum of money into the Maltese Cross Ranch, Roosevelt had his own cabin built, which he later...

A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....

mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
