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...
Near-Bed Sediment Concentration in Non-Uniform Flows Over Gravel Beds
The calculation of near-bed sediment concentration is formulated in terms of equations governing the dispersion of heavy particles in non-uniform turbulent shear flows over stable gravel...
Analytical and Numerical Modeling at High Sediment Concentrations
Methods for classifying sediment-water mixtures according to material concentration and rheologic properties are discussed. Results from laboratory and field measurements show that bed...
Stochastic Characteristics of Cobble-Gravel Bed Load Transport
Prototype tests of stochastic characteristic of cobble-gravel bed load transport have been done in Dujiangyan reach of Minjiang River in China in 1977-1985. All of 718 sample data from...
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...
Mathematical Modeling of Delta Deposits and Retrogressive Erosion in Reservoirs
A hybrid computer model which simulates mainly delta deposition and retrogressive erosion in reservoirs is described. Basic equations that govern the flow and bed changes used in the model...
Predicting Channel Recovery from Sand and Gravel Extraction in the Naugatuck River and Adjacent Floodplain
Gravel extraction at five sites along the Naugatuck River in Connecticut is of sufficient magnitude that channel recovery to pre-mining morphology is expected to require up to several...
Channel Response to SCS Type-C Grade-Control Structures on Burney Branch, Mississippi
Five SCS Type-C grade-control structures were installed in Burney Branch in 1980 to remove 59.4 feet (18.1 m) of grade. The performance of the structures was evaluated in 1984 after they...
The Effects of Sediment Transportation Changes on Aquatic Habitat
Sediments are a natural part of the riverine and estuarine environment. However, if the sediment load changes or bed sediment type occur, direct and sometimes detrimental and sometimes...
Development and Application of the Chesapeake Bay Eutrophication Model
The paper discusses the formulation of a steady-state coupled hydrodynamic/water quality model of Chesapeake Bay. The intent of this model was to provide insight into the processes and...
Sediment Variability Mark Twain Lake, Missouri
This paper looks at the historical variability in suspended sediment loads in the Upper Salt River Basin above Mark Twain Lake, Missouri in an attempt to assess the magnitude of suspended...
Stormwater Management by Utility Approach
Traditional methods of financing municipal stormwater operations and improvements through general city fund revenues has passed. A utility approach providing a continuous, uniform flow...
