Embankment Dam Safety
Procedures for identification and evaluation of conditions which can lead to catastrophic dam failure through either piping or deep seated instability of the downstream surface are presented....
Risk Assessment: A Tool for Dam Rehabilitation Decisions
A phased approach to the dam rehabilitation decision problem is presented. The approach is based on viewing the newer dam safety evaluation approaches of incremental damage assessment...
Design Considerations for Raising Existing Dams for Increased Storage
While a number of new dams have been constructed in the United States and other countries in recent years, much of the construction activity related to dams has involved the raising of...
Roller Compacted Concrete for Embankment Overtopping Protection
In the first National Dam Safety Inventory and inspection performed by the Corps of Engineers, the majority of deficiencies found were related to the inability of the project to retain...
Seepage Control in Dam Rehabilitation
This paper is concerned with the control of seepage problems which develop in existing dams. It is prefaced with a discussion of attitudes and experiences that have evolved over the last...
Improving Seismic Safety of Dams in California
A search of the dam files at California's Division of Safety of Dams has revealed that at least 94 dams have been improved for seismic stability. The results of the search are tabulated...
Improving Dam Safety Using a Fin Drain
Bloemhoek Dam is an embankment dam with a maximum height of 21 m, which leaked severely after first filling in 1978. This leakage resulted in the development of `boils' over a portion...
Certified Safety Assessment of Zoccolo Dam
The paper reports one of the activities carried out in the framework of a so called `certified assessment of safety' program activated by ENEL SpA - Italian National Electric Board - in...
Michigan Dam Safety Inspection
This paper describes the new dam safety act which took affect in Michigan in 1990. This act provides for regular inspection of almost 900 dams in Michigan that meet the size and storage...
Coolidge Dam Abutment Stability and Stabilization
This paper focuses on left abutment stability assessments and stabilization measures at Coolidge Dam, Arizona. Initial assessment of abutment stability was based on limited rock strength...
Dam Safety: A State's Perspective
The State's role in the rehabilitation of dams is discussed. The author presents a national picture of dam safety, describes some dam failure statistics on type of dams that have failed,...
Seismic Safety Modification of an Old Earthfill Dam
Chollas Dam was built as a water supply reservoir for the City of San Diego. The reservoir is no longer a part of the municipal water system but has been operated since 1966 as a recreational...
The Causticity of Accelerator for Shotcrete and its Impairment on Strength of Shotcrete
How on earth is the toxic and caustic injury of accelerator for shotcrete to operators and animals? How about its impairment on strength of shotcrete? The paper gives some reports and...
IVHS: The Invisible Revolution
Federal funding for intelligent vehicle highway systems has increased a hundredfold since 1989, from $2 million to almost $200 million. Transportation planners are looking increasingly...
Preliminary Assessment of Fault Rupture Hazard at the Yucca Mountain Site Based on Expert Judgement
The judgments of seven earth science experts were elicited to quantify the uncertainties associated with the likelihood of fault displacement through the proposed repository at Yucca Mountain...
The Development of the CRWMS Transportation System
The Transportation System of the Civilian Radioactive Waste Management System (CRWMS) is being developed using a system engineering approach to ensure it is properly integrated into the...
Development of the Planning and Control Segment, CRWMS Transportation System
This paper discusses the current plans for the development of the Planning and Control segment of the SRWMS Transportation System. Each of the four Planning and Control subsystems are...
Development of the Service & Maintenance Segment of the Transportation System
This paper discusses the progress to date in establishing the Service and Maintenance Segment of the Transportation System required to maintain the equipment required to transport spent...
Development of the Field Operations and Carrier Segments, CRWMS Transportation System
This paper discusses the current status and plans for the development of the Field Operations and Carriage segments of the Transportation System of the Civilian Radioactive Waste Management...
The Impact of Safety Analyses on the Design of the HWVP Vitrification Plant
Accident analyses are being performed to evaluate and document the safety of the Hanford Waste Vitrification Plant (HWVP). The effects of worst-case accident scenarios are evaluated by...
