 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...

The Army Corps of Engineers has released a draft for the 2008-09 Annual Operating Plan for the Missouri River. Bismarck will host one of six scheduled public meetings in October. That meeting is set at 7 p.m. Oct. 16 at the Ramkota. The plan presents information on the anticipated regulation of the Missouri River main stem reservoir system for 2009 and the remainder of 2008. Comments, both oral and written, will be accepted by corps until Nov. 21. The draft plan proposes two "spring...

WARREN - The annual dinner and meeting of the Knox-Lincoln Soil and Water Conservation District will be held Thursday, Nov. 6, at the North Nobleboro Community Hall on Upper East Pond Road. Dinner is scheduled to begin at 6:30 p.m. followed by brief reports from the U.S. Department of Agriculture's Natural Resources Conservation Service and Farm Service Agency and a presentation of the district's annual awards, which will include the 2008 Outstanding Cooperator of the Year and the 2008...

By William M. Welch Along with wild salmon and steelhead trout, the Pacific Northwest soon may have another endangered species: the driveway carwash. Washing your car or boat in the driveway or street is a residential ritual as American as backyard barbecues. But the state of Washington is telling its local governments they must prohibit home car washing unless residents divert the wash water away from storm drains, where they say it causes water pollution. "I understand this is...

By KEN MIDKIFF Nyah, nyah, nyah. Told you so, told you so. OK, that's somewhat childish. But that was my first reaction when I learned that Philips Lake (or Bristol Lake, or whatever it is called these days) was recommended for placement on the state's "impaired waterbody" - or 303(d) - list. This documents that Philips Lake is officially "waters of the state" and "waters of the United States." It is not a farm pond, where all of the waters are contained within one property. Rather the...

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...
