Using existing natural resources conservation service flood control structures for potential water supply in Georgia
Proceedings of the 2009 Georgia Water Resources Conference, April 27, 28, and 29, 2009
Athens, Georgia.The Georgia Soil and Water Conservation
Commission (GSWCC) is charged with coordinating the
operation and maintenance of 357 USDA/Soil and Water
Conservation District sponsored watershed dams in
Georgia. A majority of these dams were built during a
program that began in 1957 that encouraged the
construction of watershed dams designed to serve as
sediment traps and to provide flood protection for
agricultural lands in what was once considered to be rural
Georgia. Most of these watershed dams are maintained
and operated by soil and water conservation districts. In
a few cases, cities or counties have the responsibility to
operate and maintain the structures. GSWCC, in
coordination with the USDA Natural Resources
Conservation Service (NRCS), completed a study by a
private engineering firm to assemble data that established
viability for municipal and industrial (M&I) water supply
for an abbreviated list of 166 of the 357 watershed
structures. This data included a preliminary analysis of
yield potential of the watershed structures and associated
stream, and dam proximity to existing surface water
intake. Environmental issues included trout water,
threatened and endangered species, wetlands impacted,
streams impacted, and potential impacts to cultural
resources. Ultimately 20 dams were selected for detailed
water supply assessments. Each assessment included a
detailed analysis of yield potential for the structures to
include use as pump storage facility, an estimate of
current and future water demand based on population
projections, and the identity and quantity of
environmental issues. Detailed cost estimates addressed
construction costs, costs associated with the mitigation of
environmental impacts and costs for land rights required
to secure ownership of these dams.Sponsored by:

A Perspective on Economic Impact
The institutions responsible for water resources management in the United States have originated as political responses to major social issues. Each agency institutionalized a procedure for structuring and comparing alternatives in the formulation of its total program. Each agency originally sought to promote effective resolution of its social issue (flood control, development of arid lands, soil erosion, etc.), but more recent efforts have sought better coordination among agency practices through a common procedure largely derived from economic theory. Any procedure, however, varies in application with the interpretation and judgment of individual planners. Today, public pressures have brought political directives requiring consideration of the local and nationwide impacts of projects that occur through direct, indirect, and secondary means in the spheres of economic, social and environmental effects.
The body of the study reviews fourteen specific impact issues with the goals of providing planners a methodology for dealing with each one and of providing the theoretically inclined a basis for improving each methodology. The issues are reservoir effects on local property values, reservoir effects on the economy of the local county, changes in income and employment patterns around large reservoirs, patterns of land use change around reservoirs, reservoir effects on revenues and expenditures of local government, reservoir recreation benefits, application of marginal economic analysis to reservoir recreation planning, economic value of natural areas for recreational hunting, for stream fishing, the personal value of real property to its owner, reservoir project caused income redistribution, achievement of more flexible procedures for reservoir operation in order to match changes in demand for project output with time, estimation of flood damages by the time pattern in which they occur, and operation of reservoir systems for flood control. Each study ls presented in detail in a referenced report, and this report discusses the significance of the findings of the studies, individually and as a group
Effect of aliskiren on post-discharge outcomes among diabetic and non-diabetic patients hospitalized for heart failure: insights from the ASTRONAUT trial
Aims The objective of the Aliskiren Trial on Acute Heart Failure Outcomes (ASTRONAUT) was to determine whether aliskiren, a direct renin inhibitor, would improve post-discharge outcomes in patients with hospitalization for heart failure (HHF) with reduced ejection fraction. Pre-specified subgroup analyses suggested potential heterogeneity in post-discharge outcomes with aliskiren in patients with and without baseline diabetes mellitus (DM). Methods and results ASTRONAUT included 953 patients without DM (aliskiren 489; placebo 464) and 662 patients with DM (aliskiren 319; placebo 343) (as reported by study investigators). Study endpoints included the first occurrence of cardiovascular death or HHF within 6 and 12 months, all-cause death within 6 and 12 months, and change from baseline in N-terminal pro-B-type natriuretic peptide (NT-proBNP) at 1, 6, and 12 months. Data regarding risk of hyperkalaemia, renal impairment, and hypotension, and changes in additional serum biomarkers were collected. The effect of aliskiren on cardiovascular death or HHF within 6 months (primary endpoint) did not significantly differ by baseline DM status (P = 0.08 for interaction), but reached statistical significance at 12 months (non-DM: HR: 0.80, 95% CI: 0.64-0.99; DM: HR: 1.16, 95% CI: 0.91-1.47; P = 0.03 for interaction). Risk of 12-month all-cause death with aliskiren significantly differed by the presence of baseline DM (non-DM: HR: 0.69, 95% CI: 0.50-0.94; DM: HR: 1.64, 95% CI: 1.15-2.33; P < 0.01 for interaction). Among non-diabetics, aliskiren significantly reduced NT-proBNP through 6 months and plasma troponin I and aldosterone through 12 months, as compared to placebo. Among diabetic patients, aliskiren reduced plasma troponin I and aldosterone relative to placebo through 1 month only. There was a trend towards differing risk of post-baseline potassium ≥6 mmol/L with aliskiren by underlying DM status (non-DM: HR: 1.17, 95% CI: 0.71-1.93; DM: HR: 2.39, 95% CI: 1.30-4.42; P = 0.07 for interaction). Conclusion This pre-specified subgroup analysis from the ASTRONAUT trial generates the hypothesis that the addition of aliskiren to standard HHF therapy in non-diabetic patients is generally well-tolerated and improves post-discharge outcomes and biomarker profiles. In contrast, diabetic patients receiving aliskiren appear to have worse post-discharge outcomes. Future prospective investigations are needed to confirm potential benefits of renin inhibition in a large cohort of HHF patients without D
A Novel Approach to Writing Texts
Traditional texts fall short of capturing student interest or enthusiasm for a subject. Educators have also found that many textbooks lack reader comprehensibility in relating the substance to real life situations. The author believes that he has found a solution to both problems. Teaching production management from his “novel-text” has had excellent results. The author feels that more novel-texts will greatly improve students’ understanding of, and preparation for business. He includes some suggestions for the authoring of novel-texts
