Water Balance Approach to Prediction of Seepage From Mine Tailings Impoundments, Part II: Theoretical Aspects of Water Balance Approach to Seepage Modeling and Detailed Case History Results
Some of the most significant volumes and rates of interstitial tailings water discharge generally occurs during the initial portions of the primary consolidation process. During primary...

Seepage Control for Embankment Dams USBR Practice
The current Bureau of Reclamation approach to seepage assessment, analysis, and design for embankment dams is described. The advantages and appropriate applications for the analysis programs...

Grout Penetrability
The ability of a grout to penetrate a formation is always a selection requirement for projects in which fracturing is undesirable. The major grout properties affecting penetrability are...

Cement Grouting: Water Minimising Practices
Water gives cement grout its mobility, but the water needed for mobility exceeds hydration requirements substantially in most applications. If this excess water is allowed to collect and...

Some Aspects of Analysis and Prediction of Subsidence
A procedure based on the nonlinear finite element analysis was investigated for the prediction of subsidence caused by longwall mining. This paper presents a case study involving predictions...

Noise Characteristics of Alternative Urban Transit Technologies
The noise characteristics of alternative transit technologies for an urban area are summarized. Among the transportation technologies considered are a busway system, light rail transit...

Summary of the Accomplishments of the Federal Rail Transit Vibration and Noise Control Technology Program
The U. S. Department of Transportation's Urban Mass Transportation Administration and Transportation Systems Center have played an active role in assisting the U. S. rail...

Innovative Strategies to Improve Urban Transportation Performance
The field of urban transportation is facing some severe challenges. Roadways continue to deteriorate, the financial condition of public transit systems is abysmal, and general productivity...

High Strength Steel
A Wall Street Journal story in January 1984 described a number of bridges, buildings, automobiles, buses and other structures made of high-strength...

Checking Off CADD Priorities
Diving head on into new computer aided design and drafting (CADD) hardware and software without considering their effects on firm or university's operation is as bad as ignoring...

Civil Engineering in the Arctic Offshore
The 123 papers included in this publication describe the present state of practice, consider emerging concepts and requirements, define research and development needs and critique present...

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...

Organization and Management of Public Transport Projects
Transit development projects are undertaken to help satisfy escalating transportation needs in modern cities. The projects address an array of technical, social, and environmental considerations....

Evaluation of Pretreatment and Sludge Disposal Plans
A spreadsheet model is developed to assist municipal managers in evaluating industrial wastewater pretreatment plans and sludge disposal criteria. A case study is presented....

Modeling Contaminant Fate and Transport in Ground Water Systems
Determination of the fate and transport of contaminants in subsurface environments has been aided by recent advances in our understanding of ground water hydrodynamics and subsurface solute...

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...

Successive Application of Reservoir Simulation Models--A Case Study
Replacement of the conventional method of generating hydrology by a well established reservoir simulation model renders enormous amounts of flexibility and savings in computation time....

Optimal Operation of a System of Lakes for Quality and Quantity
A methodology is presented combining simulation and optimization techniques for determining operation strategies for a system of lakes in the presence of quality and quantity constraints....

Legal Constraints on the Transport of Water
Legal constraints on water transport are based on legitimate concerns for protecting the future interests of the area of origin, but such constraints sometimes appear overly restrictive...
