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...
Fault Diagnosis of Hazardous Waste Incineration Facilities Using a Fuzzy Expert System
The use of an expert system along with fuzzy fault tree analysis is discussed in connection with fault diagnosis of a hazardous waste incineration facility. This fault tree is a diagrammatic...
An Expert System for Inactive Hazardous Waste Site Characterization
The area of hazardous waste management is a broad and multidisciplinary field requiring expertise in engineering, geology, chemistry and toxicology, and is an ideal area for the application...
An Analysis of Traffic Signal Safety Improvements
Identifying high accident rate locations and determining that they have an overrepresented type or pattern of accidents is an important first step in the safety improvement process. However,...
Fire on the Water
Incineration is a promising hazardous waste disposal technique. However, nobody wants an incinerator constructed near him, so waste handlers are considering burning hazardous wastes at...
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...
Explosion Hazards to Urban Structures
Manufacture, storage and transportation of chemicals capable of exploding at energy levels comparable to TNT has increased in recent years. Land areas adjoining such facilities and transportation...
Seismic Restraint of Hazardous Process Piping
The lack of appropriate guidelines for the design and installation of hazardous process piping in industrial facilities has created a potentially dangerous situation. Process piping carrying...
A Recommended Federal Action Plan for Reducing Earthquake Hazards of Existing Buildings
In September 1985 a Five-Year Plan for reducing earthquake hazards of existing buildings was submitted to the Federal Emergency Management Agency. This plan, prepared by the Applied Technology...
Expert Systems in Civil Engineering
The importance of expert systems, also referred to as knowledge based expert systems, has been growing in all areas of civil engineering practice. The papers in this book were presented...
Chloramines: A Better Way?
Chlorination of drinking water has been linked to the formation of carcinogenic trihalomethanes (THMs). By adding ammonia to the water, the chlorine becomes chloramines which don't...
Recyclying of Dust from Electric Arc Funances�An Experimental Evaluation
Each year the electric arc steelmaking industry generates approximately 650,000 tons of dusts containing valuable metallic resources such as iron, zinc, lead, and chromium. EAF dust is...
Emission and Control of Volatile Organics in Hazardous Waste Landfills
Landfill simulation and modeling can provide a useful tool in the management of hazardous wastes to estimate the vapor phase emissions of pollutants so that a realistic assessment can...
Testing of Permeable Materials for Retaining Contaminants in Subsurface Leachates
The use of a permeable, retentive treatment system could remove both organic and inorganic contaminants while still allowing flow. A testing procedure for determining the amounts of priority...
Permeability of Grouts Subjected to Chemicals
This paper presents the more recent results of a testing program which evaluated the long-term resistance to percolation of grouted soils, using acrylate, urethane and cement-bentonite...
A Field Study of Water Movement Through Clay Liners
A monitoring system has been designed for the field verification of a numerical model of water movement through the cover clay liner of hazardous waste landfills. The most unique aspect...
Design of Final Covers for Landfills
Final covers or caps are incorporated into a completed landfill to limit the amount of moisture percolation through waste materials. A properly designed final cover system provides the...
Integration of EPA Guidelines Air Quality Models with Human Exposure/Risk Estimation Procedures
Techniques, based on dispersion models which are currently available, for performing population and maximum individual exposure and risk assessments due to ambient air emissions are described....
Unit Operations Approach in Exposure/Release Evaluation for New Chemicals
The unit operations approach may also be applied to the estimation of potential exposure and release of toxic materials from the manufacture and/or processing of new chemicals. By characterizing...
