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...

Collection, Quality Control and Dissemination of Weather Data for Irrigation and Other Operations in an Automated Setting
High technology has made it possible to completely automate the collection of weather data. Care must be taken in designing the automated system to generalize the software components thereby...

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...

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 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...

Geotechnical and Hydraulic Stability Numbers for Channel Rehabilitation: Part II, Application
Stability numbers for bank stability (Ng) and bed stability (Nh) have been developed. Optimum placement of...

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...

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...

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....

A Marina Model of Continuous Loads and Equilibrium
For projects requiring dredge and fill permits from the Florida Department of Environmental Regulation (FDER) the impact on water quality is one of the primary areas of concern which must...

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...
