Ultrasonic Flow Meter Testing
Six ultrasonic flow meters were tested in a hydraulics laboratory. Accuracies better than 2% were obtained with two transit-time meters on 14 inch diameter steel tubing. Poorer accuracies...
Geohydrologic Aspects of Water-Quality Problems of the San Joaquin Valley, California
Salinity and selenium concentrations in shallow ground water of the western San Joaquin Valley, California, are related to the geomorphology and hydrology of the alluvial fans. High salinity...
Near-Real Time Weather Information for Irrigation Management in Arizona
The Arizona Meteorological Network (AZMET) is a near-real time ag-weather information system for Arizona. A single personal computer running inexpensive bulletin board software controls...
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...
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 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...
Closed-Loop Control for Hydraulic Laboratory Operation
The implementation of Closed-Loop Feedback Control in the Bureau of Reclamation's Hydraulic Laboratory flow delivery system has provided an important new modeling tool for...
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...
Evaluating Flood Hazards on Alluvial Fans
In 1982, the Federal Emergency Management Agency (FEMA) developed a methodology for the determination of flood hazard zones and base (100-year) flood elevations on alluvial fans for administering...
Probabilistic Maintenance Opportunities
The Bureau of Reclamation has instituted a number of operation and maintenance oversight activities to ensure that Reclamation and water-user operated projects are operated and maintained...
Comparison of Vertical Velocity Measurements in the Great Lakes Connecting Channels with Theoretical Profiles
Vertical distribution of velocities was measured with an upward looking acoustic Doppler current profiler in the upper St. Clair River during November 1984 - April 1986 and the Detroit...
A Measure of Reservoir Efficiency
The notion of reservoir efficiency is defined for a water supply reservoir operated according to the standard policy, that is, one where the release is constant whenever physically possible....
The Life and Science of R. A. Bagnold
The purpose of this paper is to highlight and honor the exciting life and many significant contributions made by Brigadier Ralph A. Bagnold to our understanding of hydraulics and sediment...
River Sedimentation
This paper discusses Chapter 4 of the U.S. Army Corps of Engineers Engineer Manual of Sedimentation Engineering. The chapter identifies potential river sedimentation problems, associates...
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....
Sediment Survey of Lake Powell
The 1986 Lake Powell Sediment Survey documented the present storage-elevation relationship and loss of storage from sediment accumulation since the reservoir began filling. From the calculated...
Expert System for Mixing Zone Analysis of Aqueous Discharges (CORMIX1): Further Developments
Two recent publications have reported the development of the Cornell Mixing Zone Expert System (CORMIX) for the analysis, prediction and design of aqueous toxic or conventional pollutant...
Task Committee Report on Reliability Analysis of Water Distribution Systems
The results of the ASCE Hydraulics Division Task Committee on Reliability Analysis of Water Distribution Systems are summarized in a very comprehensive report entitled Reliability Analysis...
