TTU Researcher Comments On Dam Study

Researchers investigating how large dams can affect local climates say those dams have the clear potential to drastically alter local rainfall in some regions.  A study by researchers at Tennessee Tech University, Purdue University, the University of Colorado and the University of Georgia concluded that artificial reservoirs can modify precipitation patterns. The study was published in Geophysical Research Letters, and marks the first time researchers have documented large dams having a clear, strong influence on the climate around artificial reservoirs. Tech researcher Faisal Hossain says it's an influence markedly different from the climate around natural lakes and wetlands. He says the results should spur consideration of more robust management of dams and set the stage for further research on the regions and climates to focus on.
