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...
Use of Asphalt in Treatment of Dam Foundation Leakage, Stewartsville Dam
This paper presents the recent development and application of a hot asphalt grouting technique used to stop a 5,000 Imperial Gallons Per Minute (IGPM) (22,000 lpm) dam leakage under full...
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...
Computer-Assisted Grouting Evaluation Systems
Electronic monitoring of cement pressure grouting at Ridgway Dam provides a powerful tool for geologic assessment of drilling and grouting results. Graphic surveillance and analysis of...
Fracture Mechanics Analysis of Massive Hydraulic Fracturing Containment
The hydraulic fracturing containment problem is the subject of the present investigation. Unlike previous studies, the interface crack geometry with the correct crack tip singularity was...
A Tale of Six Cities
Battle Creek is a four mile urban stream that had an erosion problem that was accelerating with urbanization of its watershed. Erosion created unstable ravine slopes over 60 feet high,...
Challenges to Civil Engineering Educators and Practitioners?Where Should We Be Going?
The papers included in this publication present an overview of the current state of civil engineering education and resolutions for future development in the field. Six key areas are covered:...
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...
Quality in the Constructed Project
The purpose of the workshop summarized in this book was to develop an agenda for ASCE actions to promote quality in the constructed project. The papers, discussions and session reports...
Computer Impacts on Water Resources Engineering
Computation capability has increased by a factor of one million over the past 30 years and has contributed greatly toward data management and the application of available technology to...
Computers in a Planning Context: Another Reality
Over the past twenty years water resources planning has seen a great increase in the development of computer methods of analysis. This has transformed the way the hydrology, hydraulics,...
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...
Micro Use in Water Management in the Brazos Basin
The Brazos River Authority, an agency of the State of Texas created to conserve and develop the surface waters of the 42,000 square mile (110,000 km) Brazos River Basin, is in the midst...
Geographic and Spatial Data Management and Modeling
A geographic information system is a computer based technology for storing and using spatial data. Many alternative methodologies exist for managing the three general types of spatial...
A Micro-Computer GIS for Water Resources Planning
Recent developments in micro-computers have enabled water resources engineers to utilize advanced computer methods and interactive color graphics for the analysis and planning of water...
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...
Stochastic Modeling of Mean Areal Precipitation for Generating Synthetic Streamflows
Statistical precipitation models used as input to conceptual hydrologic models, offer an alternative mechanism for simulating streamflow. In sparsely gauged catchments, or areas where...
