Seismic Counter-Measures for Buried Pipelines
This paper deals with the seismic counter-measures for mitigating hazards from earthquake damages to buried water and sewer pipelines. To achieve an overall program for the earthquake...

Computer Control for Salt Lake City Water System
In 1978 the Department of Public Utilities in Salt Lake City began to develop a computer system to aid in the operation of the water system. The Department of Public Utilities computer...

Geotechnical Aspects of Karst Terrains
Exploration, Foundation Design and Performance, and Remedial Measures
The presence of solution cavities in karst terrains poses some unique problems in site exploration, design of foundations, and in remediation of problems with existing structures. Case...

Mine Induced Subsidence
Effects on Engineered Structures
The influence of mine subsidence on engineered structures is a growing concern of the United States coal industry. This book contains a collection of case histories of the control and...

Changing Role Between State and Federal Agencies
The paper discusses the title subject from the perspective of someone working in a state agency. The federal agencies discussed include the U.S. Army Corps of Engineers, Bureau of Reclamation,...

Furrow Irrigation Performance Using Real Time Control
Computer simulations were conducted, using a simple feedback control algorithm, to determine the potential for improvement of irrigation performance using real-time feedback control. Field...

Proposed Improvements in Lateral Canal Operations
Uniform and flexible supplies of irrigation water are required for farmers to make the best use of their on-farm application systems. Results of a study of deliveries at the lateral canal...

Irrigation and Nitrogen Management Impacts on Ground-Water Quality
The effect of irrigation management and nitrogen management on ground-water quality has been evaluated for four years on a sandy loam Coastal Plain soil. Nitrogen sidedressing and fertigation...

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...

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...

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...

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....

Calibration of Water-Velocity Meters
The U.S. Geological Survey, Department of the Interior, as part of its responsibility to appraise the quantity of water resources in the United States, maintains facilities for the calibration...

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...

Estimation of Urban Stormwater Quality
Two data-based methods for estimating urban stormwater quality have recently been made available - a planning level method developed by the U.S. Environmental Protection Agency (EPA),...

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

Morphologic and Hydraulic Adjustments of Red River from Shreveport, LA to Fulton, AK, between 1886 and 1980
Morphometric data (channel width and depth and slope) from 4 hydrographic surveys of Red River (1886, 1938, 1968, 1980) from Shreveport to Fulton and specific-gage analyses for the gages...

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...

Summary of Floods and Droughts in the United States
This paper describes a current national analysis of streamflow data being conducted by the U.S. Geological Survey to identify and map, in a consistent State-by-State format, the frequency...

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...
