The likely difference? Rain and runoff. Without rain flushing pollutants into the river, test results looked pretty good. The snapshot measures conditions across the watershed in a two- hour period. Last year's snapshot, taken after significant rainfall, showed high levels of pollutants across the...

Princeton researchers have invented a method for turning simple data about rainfall and river networks into accurate assessments of fish biodiversity, allowing better prediction of the effects of climate change and the ecological impact of man-made structures like dams.The mathematics behind the new method also can be used to model and predict a wide range of other questions, from the transmission of waterborne illnesses to vegetation patterns on land adjacent to rivers.The researchers, who...

A USDA study suggests that planting herbicide-tolerant crop varieties and using contact herbicides can reduce herbicide loss and concentrations in runoff.The residual herbicides commonly used in the production of corn and soybean are frequently detected in rivers, streams, and reservoirs at concentrations that exceed drinking water standards in areas where these crops are extensively grown. When these bodies of water are used as sources of drinking water this contamination can lead to...

By Thomas J. Dolan, The Buffalo News, N.Y. Sep. 29--Gary Wright steered his riding mower toward the pond behind his home on Old Goodrich Road in Clarence. It was May, and the dandelions needed mowing. Moments later, Wright was shocked to see that his 150-foot-wide trout pond, which a day before had been overflowing with the spring runoff, was almost empty. "My 12-foot-deep pond was approximately 4 feet deep," Wright said. Looking beyond the pond, Wright noticed a construction crew...

By Kalaba, Ljubisa Wilson, Bruce G; Haralampides, Katy Precipitation that falls on compost sites picks up organic material from the windrows and the composting pad. The resulting runoff can contain high levels of nutrients, suspended solids, and organic matter, making it unsuitable for direct release into a receiving water body. Many jurisdictions require that the runoff from these sites be collected in a detention pond. Unfortunately, some of the recommended or required procedures for...

WEST LAFAYETTE, Ind. - From suburban driveways to the sprawling lots that spring up around big retailers, Americans devote lots of space to parking spaces "“ a growing land-use trend that plays a role in heating up urban areas and adding to water pollution, according to a recent study. Purdue University researchers surveyed the total area devoted to parking in a midsize Midwestern county and found that parking spaces outnumbered resident drivers 3-to-1 and outnumbered resident families...

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...
