Snowmelt 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. The study, led by a NASA scientist and funded by the agency and the National Science Foundation, showed peak spring runoff now comes three weeks earlier than before the region was settled and soils were disturbed. Annual runoff is lower by more than...

HARRISBURG, Pa., Aug. 20 /PRNewswire-USNewswire/ -- The Department of Environmental Protection is providing municipal drainage system operators a nine-month extension of their existing general permit to better coordinate implementation of new permitting requirements. The extension applies to general permit PAG-13, which governs how municipal separate storm sewer systems handle stormwater runoff in urban areas. These systems, commonly referred to as MS4s, are publicly owned networks of...

Reducing the runoff from plant nutrients that can eventually wash into the Chesapeake Bay could someday be as easy as checking the weather forecast, thanks in part to work by U.S. Department of Agriculture (USDA) scientists. One way farmers manage manure from their livestock is by applying it to crop fields, which increases soil levels of nitrogen and phosphorus. But when it rains, the nitrogen and phosphorus in freshly applied manure is much more likely to run off and pollute nearby water...

Arsenic in food supplements passes through chickens, then passes through the field Fields amended with poultry litter can accumulate significant levels of arsenic, according to studies by USDA-Agricultural Research Service (ARS) scientists and associates. These findings provide key information about the agricultural pollutants that can build up in agricultural soils over time"”and possibly migrate into nearby streams and rivers. Poultry producers have sometimes supplemented chicken...

NOVATO, Calif., Aug. 9 /PRNewswire/ -- Today, as the California Senate considers major new recommendations to increase freshwater flows to the San Francisco Bay-Delta estuary, the Bay Institute released Gone with the Flow, a primer on how flows support a healthy ecosystem, and how the lack of flow is degrading that ecosystem to the point of collapse. The primer is available for free at http://www.bay.org/assets/Gone%20with%20the%20Flow%20WEB%20FINAL.pdf. "Flow is the most important driver...

LONGMONT, Colo., July 20 /PRNewswire/ -- In an effort to cool buildings, reduce stormwater runoff and restore the natural environment, cities increasingly are turning to "green roofs." Municipalities can't rip up the concrete and steel that cover the urban landscape, but they can use rooftops to bring nature back to high-density areas. Green roofs are rooftops that are covered with vegetation. Planted over waterproof materials, they often include underground irrigation devices such as the...

North Carolina State University researchers have developed a computer model that will accurately predict stormwater pollution impacts from proposed real-estate developments "“ allowing regulators to make informed decisions about which development projects can be approved without endangering water quality. The model could serve as a blueprint for similar efforts across the country. "The model is designed to evaluate the amount of nitrogen and phosphorus found in stormwater runoff from...

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...
