Practice of Risk Analysis in the Private Sector
Although risk-analysis is currently gaining acceptance in the decision process among engineers involved in public safety of water resources projects, the 'state-of-the-art'...
Grouting a Sand Dam
Hardy Dam, owned by Michigan's Consumers Power Co., was constructed in 1929 by dumping sand from railroad trestles for an embankment to support a concrete core wall. Some...
Design of Strontia Springs Arch Dam
The development of the layout and the history of design of the 292 foot (89 m) high Strontia Springs Dam is presented. While a brief description of the general project layout and foundation...
Geology of the Strontia Springs Arch Dam
Precambrian metamorphic gneisses comprised the foundation rock at Strontia Springs Damsite. Geologic exploration at the axis selected for the arch dam revealed a large shear zone which...
Geotechnical Aspects of Strontia Springs Arch Dam
The bedrock at the Strontia Springs damsite consists of generally excellent quality granitic and metamorphic rock, except for a wide shear zone located beneath the dam in the lower valley...
Hydraulic Design of the Strontia Springs Diversion Dam
The hydraulic features which were of primary significance for the project were the diversion tunnel and spillway. The low-level outlet valves and water-supply intake were relatively straight-forward...
Construction of Strontia Springs Dam
Strontia Springs Dam is a principal feature of the Foothills Project on the South Platte River, 25 miles southwest of Denver, Colorado. The dam provides for storage and diversion of water...
Concrete Quality Control and Quality Assurance on Strontia Springs Dam
An essential part of the construction management services provided on Strontia Springs Dam was the quality control of material, mixture proportions, and production for all concrete placed...

Seismic Analysis of Horse Creek Dam, Hudson, Colorado
On April 8, 1981, six days after a Richter magnitude 4. 0 earthquake, inspectors from the Colorado State Engineer's Office discovered a small crack in outboard side of Horse...
Filters and Leakage Control in Embankment Dams
In the practice of earth dam engineering there has been some doubt that downstream filters could be relied upon completely to control and seal concentrated leaks through impervious dam...
Embankment Seepage Control Design and Construction
For seepage control features of embankment dams, design criteria and construction practice is reviewed as it is reflected in the experience of the U. S. Army Corps of Engineers. The generally...
Abutment Seepage at Smithville Dam
After initial filling there was concern for the stability of Smithville Dam when higher than anticipated piezometric levels were experienced in the left abutment foundation. Concern heightened...
Seepage Control at Cochiti Dam, New Mexico
Significant design data, design assumptions and computations, and performance of the seepage control features provided at Cochiti Dam are summarized in this paper. The dam is a rolled...
