Grassed waterways including compost filter socks reduce soil erosion and herbicide concentrations from fields Water runoff from cropped farm fields can contain large amounts of eroded soil as well as some of the fertilizer and herbicide. Expanding on existing conservation practices, a team of scientists has tested whether compost filters socks in grassed waterways would reduce sediment flow and retain dissolved chemicals in runoff. The researchers observed reduced sediment in a non-tilled...

IRRC Also Votes to Enhance Erosion and Sediment Control, Stormwater Regulations HARRISBURG, Pa., June 17 /PRNewswire-USNewswire/ -- Governor Edward G. Rendell today praised two votes by members of the Independent Regulatory Review Commission that he said will protect Pennsylvania's streams and drinking water supplies against total dissolved solids pollution from Marcellus Shale drilling wells and other sources from stormwater runoff. The new total dissolved solids, or TDS, rules the...

The number of native fish and aquatic insects, especially those that are pollution sensitive, declines in urban and suburban streams at low levels of development "” levels often considered protective for stream communities, according to a new study by the U.S. Geological Survey. "When the area of driveways, parking lots, streets and other impervious cover reaches 10 percent of a watershed area, many types of pollution sensitive aquatic insects decline by as much as one third, compared...

MALIBU, Calif., June 1 /PRNewswire/ -- Documenting Malibu's commitment to protecting public health and improving ocean water quality, Heal the Bay's 2009-2010 Annual Beach Report Card gave several local beaches high marks for clean water and singled out the City's Paradise Cove Clean Ocean Project for praise, Malibu Mayor Jefferson Wagner said today. "We're thrilled to see Heal the Bay documenting and recognizing the City of Malibu's substantial achievements in protecting public health...

Study finds benefits of cover crops in preventing soil erosion in the winter and the following year when compared to rough tillage Cover crops may be more effective at reducing soil erosion and runoff after maize harvest than rough tillage, according to scientists from the Universit© Catholique de Louvain, in collaboration with the Independent Center for the Promotion of Forage (CIPF).The three-year study, supervised by Charles Bielders and conducted by Eric Laloy, measured erosion and...

How water runoff and subsurface infiltration affect herbicide loss Grass buffer strips are commonly used in crop production to reduce herbicide runoff. These practices are encouraged through incentives, regulations or laws, and are effective at lowering herbicide concentration in runoff. However, subsurface filtration (under the buffer strips) is not as well documented, and neither are the effects of trees integrated into buffer strips with grasses. Understanding these effects is crucial as...

HARRISBURG, Pa., March 29 /PRNewswire-USNewswire/ -- The month of April is known for rain showers, but a new Pennsylvania Geological Survey report says that the state's groundwater actually recharges the most during March. The report, "Summary of Groundwater-Recharge Estimates for Pennsylvania," was done in cooperation with the U.S. Geological Survey and is available on the Department of Conservation and Natural Resources' Web site at www.dcnr.state.pa.us/topogeo/. "This report is a...

A study by Agricultural Research Service (ARS) scientists shows that sugarcane can tolerate flooded conditions for up to two weeks. That's good news for growers who are using best management practices for controlling phosphorous runoff into the Everglades. Phosphorous stays attached to the soil for a long time even with the moderate rates of phosphorous fertilizer applied to sugarcane in Florida. If growers immediately drain their flooded fields after heavy rains have stirred up the soil,...

Stormwater runoff is the main source of polycyclic aromatic hydrocarbon pollutants to the NY/NJ Harbor. Polycyclic aromatic hydrocarbons (PAHs) are components of petroleum products such as gasoline, coal, and oil. They are also produced as by-products of the combustion of fuels including petroleum and fire wood. PAHs can cause cancer and other health effects. Because they are produced during combustion, they are ubiquitous, and their levels are high enough to be a concern in all urban...

Scientists analyze the literature to establish relationships between pollutant removal efficacy and key buffer design features. MADISON, WI, February 15, 2010 -- Agricultural nonpoint source pollution has been listed as one of the leading sources of pollution in rivers and water bodies throughout the world. Environmental regulators and scientists are making concerted efforts to reduce these pollutions using mitigation tools called best management practices (BMPs). As promising and effective...

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...
