Control of Surge Pressures in Irrigation Systems
Excessively high or low pressure within an irrigation system can result in damage to pipelines, pumps, valves, and on-farm facilities. Frequently, these pressure variations are caused...
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,...
Expert Systems Water Management: A Demonstration
Expertise is one of the major assets of the Bureau of Reclamation. However, with the current downward trend in government funding, the Bureau is facing an 'expertise crisis'....
Adsorption, Desorption and Transport of Pesticides in Groundwater: A Critical Review
Adsorption and desorption are major mechanisms affecting the transport and fate of pesticides in groundwater. Equilibrium, chemical nonequilibrium and physical nonequilibrium adsorption...
Sorption and Transport of Aldicarb Through the Vadose Zone
The literature was reviewed regarding the sorption and transport of a nonionic organic pesticide aldicarb, an extremely toxic and relatively water soluble carbamate insecticide that has...
Achieving Accurate Irrigation Water Measurements with Propeller Meters
Propeller meters are now being used extensively to help quantify and manage the huge but poorly distributed water supplies available to irrigated agriculture in the western states. Careful...
Platte River Irrigation Development: Hydrologic Myths
Several proposed municipal and irrigation developments in Wyoming, Colorado and Nebraska could impact flows along the Platte River in central Nebraska. Opposition to these projects is...
Marginal Cost Pricing: Is Water Different?
The objectives of public utility pricing are generally acknowledged to include a desire for efficient allocation of community resources, equity in allocating cost shares, stable revenues...
Financing of Urban Water Resources
This paper begins by examining recent trends in financing urban water resource systems and sets them in the broader contexts of local government finance and concerns about financing the...
Demand Management and Urban Water Supply Planning
During the past twenty years, the social sciences research has been translated into new methods and techniques of analysis which enable planners to evaluate the role of demand management...
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...
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...
The Role of Social Sciences in the Management of Surface Water Quality in the United States
This survey paper concentrates on what social science has to say about surface water quality management. Some comments are also made on the historical development of these analytical capabilities....
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...
The Role of Water Marketing in Water Allocation: A Case Study
The paper covers in some detail a specific example of water allocation, the El Paso, Texas area, to analyze what appears to be a good opportunity for successful application of water marketing,...
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...
The Application of Social Science Analyses to the Problem of Urban Drought
Past drought experiences have shown that extra storage capacity does not necessarily ensure against economic losses related to droughts. Since managers of water systems do not know the...
The Development of Metropolitan Water Markets: Seattle, Washington 1887-1987
This paper applies the case-study approach to examine the development of metropolitan water markets and its implications for central city and suburban water districts. The greater Seattle,...
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...
Mathematical Modeling of Compound Channel with High Sediment Concentration
The mathematical model for erodible channels, FLUVIAL-12, has been extended to simulate the fluvial processes in the lower reach of the Yellow River in China. Fluvial processes in the...
