There may be thousands of things large and small that can be done to better control pollution on even the smallest waterways, and a new tool developed at Purdue University may help sort out how to choose the best ones.Indrajeet Chaubey, an associate professor of agricultural and biological engineering, combined a best management practices tool with a complex genetic algorithm that can search out the best solutions for non-point source pollution control in a watershed. By analyzing data from...

A U.S. study suggests the significant increase in polyaromatic hydrocarbons entering waterways might come from driveway and parking lot sealcoats. University of New Hampshire scientists said polyaromatic hydrocarbons, more commonly known as PAHs, are found in diesel and crude oil and are considered to be carcinogenic. Our society has been sealcoating pavement for decades and there are things we've never asked about, said Associate Professor Tom Ballestero. Now we're starting to probe and ask...

 Driveways and parking lots may look better with a layer of sealcoat applied to the pavement, but the water running off the surface into nearby streams will be carrying more than just oxygen and hydrogen molecules. New research conducted at the University of New Hampshire Stormwater Center (UNHSC) indicates that sealcoat may contribute to increasingly significant amounts of polyaromatic hydrocarbons entering waterways from stormwater runoff.Polyaromatic hydrocarbons, more commonly known...

Much of Texas' wheat may be grazed as a part of a dual-use crop. But many fields are still prepared using conventional tillage, which may not efficiently capture rainfall "“ a key to economic success in a semi-arid environment, said a Texas AgriLife Research scientist.Dr. Paul DeLaune, environmental soil scientist at the Texas AgriLife Research and Extension Center at Vernon, said tillage operations can increase soil compaction, thereby increasing runoff.Each year, depending on market...

California's primary source of irrigation water is projected to go dry in 2009 due to drought, idling more than 60,000 workers and up to 1 million acres of farmland, federal officials said Friday.California water officials declared a zero allocation policy for farmers who purchase water from the federally managed Central Valley Project (CVP), and repeated their plans to reduce amounts supplied from a separate state-run water system to 15 percent of normal.The cutbacks are an enormous setback...

Muddy secrets tell of a toxic past and prompt delay in predicted cleanup date The slow natural restoration of hazardous sediments mired beneath the Puget Sound is progressing, thanks to Mother Nature and a stiff dose of federal environmental regulations. But, researchers at the Department of Energy's Pacific Northwest National Laboratory warn that this recovery process may take 10 to 30 years longer than first predicted, because of increased urban growth and its associated untreated runoff....

A group of scientists investigate innovative ways to manage urban stormwater runoff in the November-December issue of Journal of Environmental Quality. Global land use patterns and increasing pressures on water resources demand creative urban stormwater management. Traditional stormwater management focuses on regulating the flow of runoff to waterways, but generally does little to restore the hydrologic cycle disrupted by extensive pavement and compacted urban soils with low permeability. The...

The last thing anyone wants shoved in his mailbox during these tight economic times is another utility bill from the government. So it was a given that an hourlong presentation to Roanoke City Council on how to pay to improve the city's storm sewer system would be met with the level of enthusiasm usually reserved for a root canal. But like decaying teeth, crumbling infrastructure can't be ignored forever. It can be postponed, true, but inevitably one has to face the dentist. Roanoke's...

Erosion
2013-04-01 12:48:39

Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...
