A New Approach to the Design of Core Support Structures for Large LMFBR Plants
The paper describes an innovative design concept for a LMFBR Core Support Structure. A hanging Core Support Structure is described and analyzed. The design offers inherent safety features,...
Reliability-Based LRFD for Transmission Structures
A simple reliability-based Load and Resistance Factor Design (LRFD) method is proposed for the structural design of electric transmission lines. With the proposed method, the designer...
ASCE Drilled Shaft Standard: University Perspective
A critique is presented of the proposed ASCE standard on drilled shafts. Areas where major work is necessary relate primarily to the shaft design sections, establishment of loads, and...
Grouting Rehabs Earth Dam
To accommodate increased storage needs the Pennsylvania Power & Light Company had to reactivate a fly ash basin and raise an adjacent embankment dam. However, seepage through the...
Risk Analysis in Dam Safety Programs
There are about 68,000 dams in the Nation. About 95 percent of the dams are nonfederal; the balance are owned by various agencies of the federal government. Over 30 percent of the high...
Reliability Analysis as Reflected from the Fourth International Symposium on Stochastic Hydraulics
Reliability analysis is perhaps one of the most practically important branches of the general field of stochastic hydraulics. Its potential applications include quantitative evaluation...
Scour and Fill Monitoring at Lock and Dam No. 26 (Replacement), Mississippi River
Information gathered during construction of the first stage dam is presented. The information consists of data indicating flows and stages along with data obtained from surveys which monitor...
RCC Dam Incorporates Innovative Hydraulic Features
An overview of the features of Monksville Dam is presented, with emphasis on the hydraulic components of the project. This 150-foot (45-meter) high roller compacted concrete structure...
Upper Hudson River Valley Dam Break Model
In order to determine areas of inundation due to the failure of Conklingville Dam, a dam break analysis was performed, and the resulting outflow hydrograph was routed through the downstream...
Instruments Detect Dam Movement During Construction
Recent attention has been given to retrofitting electrical generation facilities at existing dams. Maintaining a safe structure during construction, and accomplishing this within a budget...
Willow Creek Dam--To Be or Not To Be
In Heppner, Oregon, several alternatives for flood control were considered. A concrete gravity dam constructed using roller compaction methods was selected because of the greatly reduced...
Operation of Glen Canyon Dam Spillways--Summer 1983
Flood control at Glen Canyon Dam is provided by a 41-ft (12. 5-m) diameter tunnel spillway in each abutment. Each spillway is designed to pass 138,000 ft**3/sec (3907. 7 m**3/sec). The...
Report on Task Committee's Scope and Findings
A Task Committee for the Design of Outlet Control structures studied the state-of-the-art practices concerning the hydraulic function, water quality, public safety, maintenance and aesthetic...
Safety, Maintenance, and Aesthetic Considerations Associated with Outlet Control Structures for Stormwater Detention Ponds
Findings of the Task Committee for the Design of Outlet Control Structures, an ASCE Technical Committee, regarding maintenance, safety and aesthetic considerations for stormwater detention...
Modeling Aeration Devices for Glen Canyon Dam
The 41-ft (12. 5-m) diameter tunnel spillways at Glen Canyon Dam experienced major damage during the 1983 spring runoff. This damage was initiated by cavitation. Hydraulic model studies...
Aeration is the Solution for Sluice Cavitation Damage at Libby Dam, Montana
Cavitation has severely damaged two of the high-head flood control sluices. The damaged areas were immediately patched; however, these patches were not considered a solution to the problem....
Prediction of Dam Overtopping Due to Mudflows
The eruption of Mount St. Helens on May 18, 1980 resulted in a small mudflow into Swift reservoir, which is located immediately south of the mountain. An engineering/geologic study was...
Modeling Analysis for Management of Artificial Recharge
The objective of these groundwater and sediment modeling studies is to determine the net change in storage and potentiometric levels within the Bunker Hill Groundwater Basin resulting...
Modifications of Dams for Recreational Boating
Many existing dams and river structures require modification, and new structures may need to include designs to allow safe white water activities. The basic problem is safety, with a long...
Bureau of Reclamation Hydraulic Laboratory
The Bureau of Reclamation used hydraulic models for the first time in 1930 in the laboratory of the Colorado Agriculture Experimental Station in Fort Collins, Colorado. In 1946 the Reclamation...
