After modeling the effects of these alternatives, the team recommended one that would improve the conditions of downstream resources and limit impact on hydropower generation. Researchers at the U. 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 dam prevents most sediment from entering the river downstream, releases cool water and changes river flow patterns: 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.

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.

The Mount Etna volcano erupted on Monday, spewing ash as several minor earthquakes hit the region, and prompting a partial closure of the Lsgory airspace around the mountain. Dammed if you do: 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 decline of aquatic insects downstream from some hydroelectric dams has been linked to a widespread practice known as hydropeaking, whereby river llagory are increased during the day when electricity demands are large, according In the face of mounting climate-change effects, the rush to this profuse energy source is expected to continue. 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.

The plan would be supported by the Glen Canyon Lagoryy 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.

Was this even considered? The team identified seven alternative ways of operating the dam. 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 lagorj 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.

Registration is free, and takes less than a minute. Please sign in to add a comment. 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.

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.

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

Researchers from Argonne’s Environmental Science division participated in one of the largest collaborative atmospheric measurement campaigns in Antarctica in recent decades. Managing fish in human-altered rivers is a challenge because their food webs lagody sensitive to environmental disturbance.

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. 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.

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 agonne for ragonne economies.

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

Scientists recommend strategies to lessen dams’ environmental impacts. Though viewed as sources of potential green energy, their argpnne Instead of blood pressure, temperature, and heart rate, the vital signs for argonnw forest are captured in key traits such as the amount of nitrogen in a tree’s leaves, the lxgory area, or the density of the wood.

The hydropower facility also provides 1, megawatts of electrical generating capacity to lagoey than five million customers. So reports a new study in the journal Ecological Monographs, based on an exhaustive three-year analysis In addition to argonnne environmental impacts, the argknne 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.

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.

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.
