The Economic Feasibility of Using Ethanol to Accelerate Groundwater Denitrification
A substantial buildup of nitrate in the groundwater of the eastern Sandhills region of Nebraska is projected by some planners. A groundwater carbon source such as ethanol promotes denitrification,...

Economic Analysis of Canal Animal Protection Measures
Justification of canal animal protection measures has been, to a degree, driven by environmental and social constraints and as a result, large expenditures of funds to protect ungulates...

Economic Evaluation of Treatment Alternatives for Nitrate-Contaminated Water Supplies
This paper discusses the economic feasibility of removing nitrates from water supplies. Potential nitrate treatment methods include ion exchange, reverse osmosis, bio-denitrification,...

Bulk Stomatal Resistance in Operational Estimates of Evapotranspiration
General relationships for estimating canopy or bulk stomatal resistance and aerodynamic resistances of grass and alfalfa reference crops for use in the Penman-J.L. Monteith equation are...

The Social Sciences and Water Resources Management
With support from the National Science Foundation, a committee of 15 persons met in Washington, D.C. in 1985 to begin the process of assessing the past and future role of the social and...

Social Science, Engineering and Water Resources Management: A Perspective
This paper shares a framework or context for professional activities of social scientists in water resources management. It emphasizes the positive opportunities for helping and not simply...

Obstacles to the Use of Social Science Analysis in Water Decision-Making, or Where's the Demand for Social Science Input?
The paper identifies characteristics of both the public decisionmaking process and the methods of social science research that result in social science inputs having little influence on...

Ideology: A Worried Analysis
The paper makes the point that social, cultural and psychological variables, that is, variables of the behavioral sciences, are meaningful to the field of natural resource management....

How Far along the Learning Curve is the Contingent Valuation Method?
The paper discusses an application of the learning curve concept to new benefit methodologies and applies the model to the contingent valuation (CV) methodology. As knowledge accumulates...

Economics, Economists, and Water Policy Advising
Subjects covered include the effectiveness of economic analysis, the economist as technician and as policy entrepreneur, and others. Economic concepts and studies can be used as a means...

Water Resources Management and Structural Change in Rural Australia
Water policies in Australia are undergoing fundamental change marked by a switch in emphasis from development of further sources of water to management of available supplies. Quite apart...

Water Rights Issues
The paper focuses primarily on the fragmented legal rights to water in the hydrologic cycle, with conjunctive use and management of interconnected water resources and with some conflicting...

Assessment of the Role of the Social Sciences in Water Planning and Management: Legal Systems and their Impediments to Change
Water resource planners and managers may not be able to do what they believe essential, or at least useful, to sound water management because the action would violate the federal constitution...

Alternatives to the Precommensuration of Costs, Benefits, Risks, and Time
The thesis advanced in this paper is that benefit-cost analysis, the present-value-of-cost (and benefit) approach, and the expected value of damage as a measure of risk all share a faulty...

The Role of Social Sciences in Putting People Into Federal Water Resources Project Planning and Evaluation
While great attention has been given to the importance of engineering, economic, and, recently, environmental factors, the need for consideration of the social impacts of projects and...

Application of Social Science Research Products in Urban Water Resources Planning
Phoenix was spurred to action in 1981 because of the projected depletion of one of its surface water supplies by the summer of 1982. In addressing the projected near-term crisis, it quickly...

Power Formula for Open-Channel Flow Resistance
This paper evaluates various power formulas for flow resistance in open channels. Unlike the logarithmic resistance equation that can be theoretically derived either from Prandtl's...

An Agricultural Watershed Environmental Study
The concerns of this study are the effects of soil and water conservation measures on a salmonid habitat for an agricultural watershed. The study includes an economic analysis in accordance...

Analysis of Spillway Failures by Uplift Pressure
Results of a model study to evaluate the development of uplift pressures beneath concrete chutes are presented. Two spillway failures are described to support the study results. Common...

Estimation of Uplift Pressure in Cracks in Concrete Gravity Dams
This paper presents an analytical solution to predict uplift pressures in cracks in concrete gravity dams. It is shown that drainage systems are effective in reducing such pressures....
