Overwinter Drawdown

After resistant species reinvade a flowage , overwinter drawdowns may no longer

NEW YORK TIMES BESTSELLER For the first time ever, an international coalition of leading researchers, scientists and policymakers has come together to offer a set of realistic and bold solutions to climate change. All of the techniques described here - some well-known, some you may have never heard of - are economically viable, and communities throughout the world are already enacting them. From revolutionizing how we produce and consume food to educating girls in lower-income countries, these are all solutions which, if deployed collectively on a global scale over the next thirty years, could not just slow the earth's warming, but reach drawdown: the point when greenhouse gasses in the atmosphere peak and begin todecline. So what are we waiting for?

'Sudden' or 'rapid' drawdown is considered to occur when reservoir or other adjacent water levels are lowered at such a rate that little or no drainage occurs in an earth slope at the time the water level is being lowered. Slope stability analyses are routinely performed to calculate the factor of safety for earth slopes subjected to this condition. This study provides a basis for a number of important conclusions regarding the accuracy and the degree of conservatism of the procedures for analyzing rapid drawdown slope stability. The best procedure should have the following characteristics: a. The procedure should employ a measure of shear strength and pore pressure that reflects the actual properties of the soils in the slopes. b. The procedures should use a soundly bases technique for relating shear strength to effective consolidation pressures. and c. The procedure should not include strength components due to to negative pore water pressures to avoid overestimating factors of safety for conditions where partial drainage occurs during drawdown. A method with these characteristics can be conceived as a combination of methods currently in use. Keywords: Effective stress analysis; Pore pressure coefficients; Shear strength envelopes.

The U.S. and Iraq have signed a Security Agreement calling for the drawdown of U.S. forces from Iraq. Multi-National Force-Iraq has issued a plan for the reduction of forces to 50,000 U.S. troops by Aug. 31, 2010, and a complete withdrawal of forces by the end of 2011. The drawdown from Iraq includes the withdrawal of 128,700 U.S. troops, over 115,000 contractor personnel, the closure or transfer of 295 bases, and the retrograde of over 3.3 million pieces of equipment. This statement focuses on: (1) the extent to which the DoD has planned for the drawdown in accordance with timelines set by the Agreement and presidential directive; and (2) factors that may impact the efficient execution of the drawdown in accordance with established timelines.
