Scientists recommend strategies to lessen dams’ environmental impacts September 8, Dams around the world provide critical water supplies and hydropower to growing communities and hundreds of new dams are proposed for developing economies.

The team identified seven alternative ways of operating the dam.

Reliable tropical weather pattern to change in a warming climate December 28, Every month or two, a massive pulse of clouds, rainfall and wind moves eastward around the Earth near the equator, providing the tropics their famous thunderstorms. Dammed if you do: The team also analyzed the overall capacity of the hydropower plant arggonne a year period. After modeling the effects of these alternatives, the team recommended one that would improve the conditions of downstream resources and aggonne impact on hydropower generation.

The report is the first step in a year experimental, management and environmental monitoring effort conducted by the U. The dam was built in for water storage and flood control and is crucial to water distribution to about 40 million people in Arizona, Colorado, Nebraska, Nevada, New Mexico, Utah and Wyoming. Department of the Interior is expected to produce a Record of Decision that identifies how the department plans to zrgonne Glen Canyon Dam for the next 20 years.

Argonne report to help dam north of Grand Canyon balance environment and hydropower needs

I have read several articles that, given the debt and the evaporation rate of Lake Powell, it would be best from a water conservation viewpoint to drain the lake and turn it back into a river. Dams around the world provide critical water supplies and hydropower to growing communities and hundreds of new dams are proposed for developing economies. The Grand Canyon will be experiencing a spring of yesteryear, as water flow rates from the Glen Canyon Dam will be significantly increased, then throttled back in a high-flow experiment that runs March 4 through 9.

Researchers at the U. The plan, known as the Glen Canyon Dam Long-Term Experimental and Management Plan and documented in a final environmental impact statement, recommends a strategy that would balance hydropower with the protection of environmental, cultural and recreational resources in the area.

The plan, which was released earlier this month, is designed to be flexible and responsive to changing conditions and new information, so that operations can be adjusted to improve conditions.

In the next few months, the U.

Managing fish in human-altered rivers is a challenge because their food webs are sensitive to environmental disturbance. For example, it has contributed to a decline in the population of native humpback chub, as well as the erosion of beaches once built and replenished from sediment transported downstream during annual floods.

Each one would implement different monthly and daily water release patterns and experimentally test special releases, such as short-duration high flows to simulate floods and build beaches, low summer flows to allow the water to warm to benefit native fish or short-term fluctuations to manage the trout population.

The dam prevents most sediment from entering the river downstream, releases cool water and changes river flow patterns: A Duke University study shows that trace elements in a fish’s ear bones can be used to identify and track coal ash contamination in the waters where it lived. In the face of mounting climate-change effects, the rush to this profuse energy source is expected to continue. Though viewed as sources of potential green energy, their construction The plan would be supported by the Glen Canyon Dam Adaptive Management Program, a successful management strategy for long-term research and monitoring of dam operations and downstream resources that has been in place for the last 20 years.

Geological Survey’s Grand Canyon Monitoring and Research Center, in coordination with the Bureau of Reclamation, the National Park Service, other agencies and the Tribes, will then implement a science program to monitor the impact of dam operations on fish populations, river sediment, vegetation, cultural resources and other environmental resources. Researchers from Argonne’s Environmental Science division participated in one of the largest collaborative atmospheric measurement campaigns in Antarctica in recent decades.

Tree rings tell the story of what’s happening physiologically as fire suppression makes forests more dense and less tolerant of drought, pests and wildfires, new research shows. Adjust slider to filter visible comments by rank. Instead of blood pressure, temperature, and heart rate, the vital signs for a forest are captured in key traits such as the amount of nitrogen in a tree’s leaves, the leaf area, or the density of the wood.

The decline of aquatic insects downstream from some hydroelectric dams has been linked to a widespread practice known as hydropeaking, whereby river flows are increased during the day when electricity demands are large, according The Mount Etna volcano aryonne on Monday, spewing ash as several minor earthquakes hit the region, and prompting a partial closure of the Sicilian airspace around the mountain.

Every month or two, a massive pulse of clouds, rainfall and wind moves eastward around the Earth near the equator, providing the tropics their famous thunderstorms.

In doing so, they measured the effects of variable water flow e.
