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

Researchers at the U. 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 agonne.

Scientists recommend strategies to lessen dams’ environmental impacts. 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.

Department of the Interior is expected to produce a Record of Decision that identifies how the department plans to operate Glen Canyon Dam for the next 20 years. Adjust slider to filter visible comments by rank.

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

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. 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 After argpnne the effects of these alternatives, the team argonnne one that would improve the conditions of downstream resources and limit impact on hydropower generation.


Dammed if you do: Tree rings tell the story of what’s happening physiologically as fire suppression makes forests more llagory and less tolerant of drought, pests and wildfires, new research shows. 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.

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

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. 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.

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. Please sign in to add a comment.

So reports a new study in the journal Ecological Monographs, based on an exhaustive three-year analysis Researchers from Argonne’s Environmental Science division participated in one of the largest collaborative atmospheric measurement campaigns in Antarctica in recent decades. 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.


The dam prevents most sediment from entering the river downstream, releases cool water and changes river flow patterns: The hydropower facility also provides 1, megawatts of electrical generating capacity to more than five million customers.

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. 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. 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.

In the next few months, the U. The report is the first step in a year experimental, management and environmental monitoring effort conducted by the U. Though viewed as sources of potential green energy, their construction In addition to analyzing environmental impacts, the team assessed how each alternative would affect power production during periods of peak demand when the value of energy is higher which occur in the winter and summer and in the mornings and evenings versus when demand is low and the value of energy is lower like during the middle of the night.
