Mohammad Golabi, a soil science professor at the University of Guam, has put his years of research on vetiver grass to practical use in shielding the reefs in Pago Bay from the harmful effects of construction-induced run-off. One of the major health hazards facing Guam's reefs is soil erosion resulting in sedimentation and suffocation of the complex organisms that make up a reef system. "Vetiver's ability to tolerate high stress situations, adapt to a variety of conditions, develop a dense...

The sand along the south-western coastal rim of Norway has drifted for more than 9000 calendar years. This was triggered by sea-level changes and human activities, new research has found. Researchers in countries such as Denmark, the Netherlands and Poland study sand drift, but most of them are focusing on sand dunes along the coastline, not on the plains further inland. "Sand dunes are dynamic. For all we know, they may have been formed last year. But sand plaines are much older and in...

WILLIAMSPORT, Pa., March 23, 2011 /PRNewswire-USNewswire/ -- The Department of Environmental Protection has ordered Chesapeake Energy to cease work on a natural gas drilling well pad for failing to comply with regulations and impacting one of Galeton Borough Water Authority's water sources. The well pad was in the site-preparation phase, which occurs before any well construction or drilling activities take place. In conducting site-preparation activities at the Beech Flats well pad in...

Drier conditions projected to result from climate change in the Southwest will likely reduce perennial vegetation cover and result in increased dust storm activity in the future, according to a new study by scientists with the U.S. Geological Survey and the University of California, Los Angeles. The research team examined climate, vegetation and soil measurements collected over a 20-year period in Arches and Canyonlands National Parks in southeastern Utah. Long-term data indicated that...

An assessment of coastal change over the past 150 years has found 68 percent of beaches in the New England and Mid-Atlantic region are eroding, according to a U.S. Geological Survey report released today. Scientists studied more than 650 miles of the New England and Mid-Atlantic coasts and found the average rate of coastal change "“ taking into account beaches that are both eroding and prograding -- was negative 1.6 feet per year.  Of those beaches eroding, the most extreme case...

Much of the Mississippi River's sediment load doesn't come from field runoff, according to work by scientists at the U.S. Department of Agriculture (USDA). Instead, the scientists with USDA's Agricultural Research Service (ARS) have confirmed that stream bank collapse and failure can be chief contributors to high sediment levels in the silty streams and rivers that flow into the Mississippi. ARS is USDA's chief intramural scientific research agency. The U.S. Environmental Protection Agency...

Archaeology is a vital tool in understanding the long-term consequences of human impact on the environment. Computational modeling can refine that understanding. But according to Arizona State University archaeologist C. Michael Barton, it takes a revolution in thought, along with the newest methods of modeling, to produce a comprehensive picture of the past that can help inform land-use decisions for our future. Barton, a professor in ASU's School of Human Evolution and Social Change, will...

Locke Island is a small island in a bend of the Columbia River in eastern Washington that plays a special role in the culture of the local Indian tribes. Since the 1970s, however, it has been eroding away at a rate that has alarmed tribal leaders. The island is part of the Hanford Reservation, which is managed by the Department of Energy. So the DOE has turned to a team of researchers headed by David Furbish, professor of earth and environmental sciences (E&ES) at Vanderbilt, to study the...

If current climate projections hold true, the forests of the Southwestern United States face a bleak future, with more severe "“"“ and more frequent "“"“ forest fires, higher tree death rates, more insect infestation, and weaker trees. The findings by university and government scientists are published in this week's issue of the Proceedings of the National Academy of Sciences (PNAS). "Our study shows that regardless of rainfall going up or down, forests in the...

Researchers from North Carolina State University have developed a sensor that allows engineers to assess the scour potential of soils at various depths and on-site for the first time "“ a technology that will help evaluate the safety of civil infrastructure before and after storm events. Scour, or erosion of soil around structures due to water flow, is responsible for a wide range of critical infrastructure failures "“ from unstable bridges to the levees that gave way in the wake...

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,...
