High Rise Design: Accounting for Column Length Changes
In the late 1950's and early 1960's, the height of concrete buildings jumped from 20 to 60 stories. During the same period, architects introduced the use of exposed...
Application of Methods of Probabilistic Characterization of Soil Properties
The use of probabilistic methods to describe soil properties has many applications. One such application that has been developed is in the area of probabilistic slope stability analysis....
River Lock Rehab: A Winter's Tale
Lock & Dam �1 on the Mississippi River between Minneapolis and St. Paul had deteriorated badly but the U.S. Corps of Engineers determined that replacement with a new structure...
The Sand Dam
Currently under construction is the 443 ft. high sand fill dam. Being erodible, pervious and liquefiable, sand would normally be considered as n unsuitable material to construct LaVueltosa...
Water Supply
The Foothills Project adds 125 mgd (5.5 m�/s) to the Denver area water treatment capacity, and saved approximately $1 million in energy costs in the first year of its operation. The $163...
Prefab Power
The Love Hydroelectric Generating Station, owned by the city of Vanceburg, Ohio, was prefabricated in France complete with all components, brought across the Atlantic and towed to Greenup...
Flood Control
The Hamilton and Riemer reservoirs were constructed by excavating pits below grade to receive flood overflows from adjacent streams. The two reservoirs are part of a 52 sq. mile (135 km�)...
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...
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...
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...
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...
