The results of optical modelling showed that the spectral diffuse attenuation coefﬁcient can be estimated with reasonable accuracy from the measured water quality concentrations. This provides more detailed
information on light attenuation from routine monitoring measurements than is available through the
Secchi disk transparency. This study improves the interpretation of water qual ... read more >>
A modeling study from the European Alps suggests that population declines to be observed during the upcoming decades will probably underestimate the long-term effects of recent climate warming on mountain plants. A European team of ecologists around Stefan Dullinger from the Department of Conservation Biology, Vegetation and Landscape Ecology of the University of Vienna presents a new modeling to ... read more >>
The 2012 Water and Health Conference: Science, Policy and Innovation, jointly organized by the Institute for the Environment and the Water Institute at UNC, will consider drinking water supply, sanitation, hygiene and water resources in both the developing and developed worlds with a strong public health emphasis.
The 2012 Water and Health Conference: Science, Policy and Innovation is accompanie ... read more >>
Arizona’s two senators, John McCain and Jon Kyl, traveled to the Navajo reservation this week to meet with Navajo and Hopi tribal leaders about a proposed water rights accord that would settle the two tribes’ claims to the Little Colorado River system.
The settlement would benefit the two tribes by providing clean drinking water piped directly into their homes, Mr. Kyl said. There is very little ... read more >>
A century ago, rural homes in the United States and Europe commonly relied on wood for heating. Now wood is making a comeback, thanks largely to pellet technology.
The energy-dense pellets, which resemble dry dog kibble and are mostly made from mill residue like sawdust and wood shavings, can be used to generate heat or electricity — or both at the same time. Demand is strong in Europe, where ... read more >>
Slowly, slowly, the Energy Department is moving forward with solidifying the liquid nuclear wastes left over from cold-war weapons production. The department said it had closed two more of the 51 underground tanks at the Savannah River Site in western South Carolina. The high-level waste was mixed with molten glass to keep it chemically locked up for millennia, and the lower-level material was mi ... read more >>
A detailed description of development of the first practical artificial leaf — a milestone in the drive for sustainable energy that mimics the process, photosynthesis, that green plants use to convert water and sunlight into energy — appears in the ACS journal Accounts of Chemical Research. The article notes that unlike earlier devices, which used costly ingredients, the new device is made from i ... read more >>
Scientists say climate change is making it tougher for Idaho reservoir managers to forecast weather, control floods and manage water for farming, recreation and fisheries. ... read more >>
LAST year was a particularly deadly year for tornadoes in the US, with the second highest death toll in 137 years. Already this year, major outbreaks have killed 63 people. All eyes are now on May, when the season usually peaks, amid talk in some quarters of another year of extremes. The result is that discussion about human influences on severe thunderstorms and tornadoes has been reignited. Suc ... read more >>
Climate change has been studied extensively, but a new body of research guided by a San Francisco State University hydrologist looks beneath the surface of the phenomenon and finds that climate change will put particular strain on one of our most important natural resources: groundwater. ... read more >>
