Soldier Creek Dam Foundation Drainage
A possible mode of failure for Teton Dam, piping of erodible core material through unsealed foundation joints, was also concluded as being possible at Soldier Creek Dam, Utah. Evaluations...
A Case History of Leakage from a Surface Impoundment
A manufacturing company constructed a 48-acre (19 hectare), unlined surface impoundment at a site in northern Texas to store wastewater. The site is underlain by unsaturated, alluvial...
Chemical Grout Curtains at Ox Mountain Dams
Grout curtains were constructed in granodiorite bedrock as part of two earthfill diversion dams at a sanitary landfill site on the San Francisco, California peninsula. The curtains are...
Computer Applications in Grouting
The first use of computers during foundation grouting was tried by the Bureau of Reclamation on Ridgeway Dam in Colorado. It was very useful in monitoring real time down hole conditions...
Oil Shale Fracture Characterization by a New Model
Fracture toughness of oil shale is a property which is essential for fracture characterization needed for energy resource development and recovery. However, a data base for fracture toughness...
Highway Noise: FHWA Requirements and Barrier Design
Since 1973, the Federal Highway Administration (FHWA) has required noise studies for nearly all proposed roadways and roadway improvements that receive federal aid. An overview of these...
Construction QA/QC Systems that Work
Case Studies
Four case studies discuss the issue of responsibility for quality assurance and quality control by describing actual situations where quality work is being done in the field. The case...
Maximum Water Source Utilization Using Lotus 1-2-3
This paper discusses the use of microcomputers to determine the optimum mix of sources for the Fargo-Moorhead area's water supply network. The area's major water...
Personal Computers and Stormwater Management Programs
Urban flooding and drainage problems are the result of complex interactions between natural and man-made systems. Comprehensive analysis of the hydrologic characteristics of these problems...
Water Resources Applications of OCAP--Ohio's CNRIS
The Ohio Capability Analysis Program (OCAP) is a computer-based natural resources information system (CNRIS) operated since 1973 by the Ohio Department of Natural Resources. The three...
Geographic Information Systems: A Planning Tool
Geographic Information Systems provide an opportunity for water resource planners to examine potential impacts of proposed plans early in the study process. Conflicts can be identified...
Storage Projection for Reservoir Systems
Two methods are studied for determining the probability distribution of future levels of storage in a reservoir system: transient analysis and Gould's probability matrix method....
Design and Operating Rules for Reservoir Storage to Offset Future Consumptive Use
The Washington Metropolitan Area (WMA) relies largely on the Potomac River for water supply. After many years of study, a coordinated regional operating plan was adopted by the water supply...
Microcomputer Analysis of Harbor Wind Drift
A microcomputer with general-purpose spreadsheet software was used to analyze wind drift on the water surface of Quincy Bay in Boston Harbor. Wind drift is the movement of the surface...
Groundwater Models: Converting Research Developments into Practical Applications
One method of bridging the gap between code developer and code applier is through separate user-friendly computer programs called preprocessors that prepare data before execution of the...
Automated Data Monitoring for Disaster Prevention
A system is now available from International Hydrological Services for use on micro-computers that will provide real-time environmental monitoring, analysis, forecasting and control. This...
Computer-Aided Drought Operations
A simulated drought operations exercise is conducted annually in the Washington, D. C. area. Local water supply utilities work with the Interstate Commission on the Potomac River Basin...
Reliability of Urban Water Supply Reservoir System
Assessment of the reliability, or risk of failure, of water supply reservoirs is dependent on several factors including reservoir volume, probability of dam failure and drought inflows....
A Case Study - Toms River Water Company, Toms River, New Jersey
Toms River Water Company provides water service to Dover Township, the Borough of South Toms River and portions of Berkeley Township, all in Ocean County, New Jersey. Existing supply facilities...
Water System Model Brought Improvements in System Performance
