Pollution Controls Increase Attendance On Beaches
2013-06-06 11:53:23

Duke University Southern California beaches with storm drain diversion systems attract millions more people annually, a new study in the journal Marine Pollution Bulletin shows. The study looked at whether improving the environmental quality of coastal areas through policy intervention had an effect on the way people use coastal areas. Researchers found a direct correlation between increased attendance and the installation of storm drain diversions at 26 beaches in Santa Monica Bay and...

NASA To Map Snowpack Of Two Major Mountain Watersheds In Colorado And California
2013-05-03 09:00:35

Alan McStravick for redOrbit.com - Your Universe Online In the very near future, the global issue surrounding the need for natural resources will shift from fossil fuels to fresh water. In preparation for this change of need, NASA has endeavored on a new airborne mission to create the first maps of the entire snowpack of two major mountain watersheds in California and Colorado. These western snow reserves, as they melt, provide greater than 75 percent of the total freshwater supply for the...

Hidden Dune Filters Used To Treat Coastal Stormwater Runoff
2013-03-19 10:43:38

North Carolina State University When it rains, untreated stormwater can sweep pollutants into coastal waters, potentially endangering public health. Now researchers from North Carolina State University have developed low-cost filtration systems that are concealed beneath sand dunes and filter out most of the bacteria that can lead to beach closures. “It was not economically feasible to use a tract of beachfront property to treat stormwater. Instead, we were able to devise a system...

National Science Foundation Changes in winter hydrology, ecology and biogeochemistry are focus of session at American Geophysical Union (AGU) conference If you're planning to skate on a frozen lake or river this winter, ski on a snowy slope, or, when spring arrives, depend on snowmelt to refill your water supply, you may need to think twice. Winter as a "species" may have evolved to be less like the winters we remember. The change has consequences for summer, too, including plants'...

A typical landscaped yard consists of lawn area and ornamental plants. If watered properly, homeowners can see the beauty, pocket some green and save some water, according to a Texas A&M University turfgrass professor. Supplemental watering of urban lawns and landscaped areas is required to keep the plants healthy through the typical long, hot and dry summers and falls in Texas, according to Dr. Richard White, Texas AgriLife Research turfgrass management scientist in College Station....

Phosphorus (P) is both an essential nutrient in agricultural fields and a contributor to poor water quality in surface waters. To encourage improved P management in fields, the P Index was proposed as a risk assessment tool in 1992. After 20 years of use, modifications, and growing pains, does the P Index accurately assess the risk of P loss? A special section being published next month in the Journal of Environmental Quality addresses that question. The collection of papers grew out of a...

U.S. Department of Agriculture (USDA) research confirms that the time-tested practice of amending crop soils with manure also can help restore soils on damaged post-mining landscapes. Thousands of acres of land with little or no vegetation, once mined for lead and zinc, remain throughout an area of southwestern Missouri, southeastern Kansas, and northeastern Oklahoma. The mining activities also left behind a legacy of lead-contaminated acidic soils, toxic smelter sites, and large...

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...
