Water and Wastewater, Time to Automate?
Water and wastewater engineers have been slow to adopt a full circle systems approach to automated monitoring and control. Such a technical tactic for controlling water and wastewater...
Demands for Innovation in Power Construction
This paper identifies some specific demands for innovation on power projects, reviews the alternatives considered to meet project objectives, and describes the resulting innovations. Examples...
Large Mat Foundation Analysis on Expansive Soil
This paper describes a comparison of predicted and observed performance of mat foundations on stiff expansive soil. Foundation performance was predicted using a new computer program BOSEF...
Systems Model for Water Supply Following Earthquakes
The water supply for San Francisco is described with emphasis on the city's auxiliary water distribution network, which provides fire protection for the most heavily built-up...
Seismic Resistance of an Elevated Water Tank?A Case Study
Current knowledge of earthquake risk and structural response has raised concern about the safety of elevated water storage tanks which were constructed several decades ago. This paper...
Earthquake Risks to Utah Water and Gas Systems
Designed to guide local earthquake hazard reduction programs, this study estimates direct aggregate earthquake damage to Davis and Salt Lake County utilities. For making these loss estimates,...
The Effects of the 1985 Mexico City Earthquake on Underground Water & Sewer Pipelines
The 1985 Mexico City Earthquake left thousands dead and many thousands more without shelter. The visible damage was immense and terrible, and familiar to people around the world through...
Control of Thistle Lake, Utah
In April of 1983, the Thistle slide blocked the flow of the Spanish Fork River and traffic using the Denver and Rio Grande Western Railroad, U. S. Highway 89, and U. S. Highway 50 and...
Engineering Implications of Impoundment of the Indus River by an Earthquake-Induced Landslide
Historical records and physical evidence indicate that in the Himalayas of northern Pakistan a huge landslide dam was caused by an earthquake in 1840. The dam blocked the Indus River,...
Professional Training Potomac Electric Power Company (PEPCO)
Training of professionals within the Generating Engineering and Construction Group at the Potomac Electric Power Company is most intensive right after hiring but continues to the executive...
Base Isolation in the Design and Construction of Power Plant Structures
This technical paper summarizes the results of some of the recent studies performed to assure technical feasibility in isolating safety-related nuclear power plant structures. The particular...
Design and Planned Use of a 2-Kiloton Eccentric Mass Vibrator
High-level testing of large civil structures is usually not practical, due to structural damage considerations and available testing equipment. However, in the case of a joint American/German...
Clean-up in the Rockies
The shallow aquifer flowing beneath the Rocky Mountain Arsenal, just outside of Denver, has become contaminated with a number of toxic substances. Until the arsenal can be cleaned-up,...
Cleaning Up Toxics
Case histories show how several different types of contamination cleanup were handled. In Attleboro, Mass., washwater, used to decontaminate equipment and tools after cyanide was removed...
Treatment in Your Own Backyard
Everyone wants the nation's hazardous waste sites cleaned up, but nobody wants the wastes disposed of near them. Therefore, cleaning up these problems at the site may be the...
Risk Assessment: Engineering Tool
In factoring in human-health impacts when tackling an environmental problem, risk assessment is often the best approach. Its use is growing fast. The technique increasingly is being used...
Dynamics of Fender and Rack Systems for Docking Ferries
A dynamic analysis of a ferry fender and rack system is developed based on the conservation of energy principle and Newton's laws of motion. The dynamics of the interaction...
Floating Bridges in Short-Crested Random Seas
Four large concrete floating bridges located in Washington State have been the subject of extensive analytical modeling for dynamic response to storm waves. The dynamic analysis of the...
Diffraction Forces on Axisymmetric Bodies
Use of a Green function satisfying the governing differential equation and all boundary conditions except those on the boundary of the structure yields an integral equation, when these...
Structural Settlements at a Major Power Plant
The foundation design for the Intermountain Generating Station was based on comprehensive geotechnical investigations that included cone penetrometer tests, borings, pressuremeter tests,...
