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...
Power from the Incineration of Wastewater Sludge
The City of Kansas City, Kansas recently completed an upgrading of their existing primary treatment and sludge handling system in preparation for the addition of a high purity oxygen activated...
Trace Toxic Metals Emissions from Hazardous Waste Incinerators
A physical model is proposed in order to explain the vaporization of metals during metallic waste incineration and is based on work performed to investigate inorganic emissions from coal...
Engineering Methodology for Delineating Debris Flow Hazards in Los Angeles County
Utilizing historical and field data, elementary geomorphology and simplified hydraulics of debris flows, a mapping strategy has been developed. The delineation procedure includes defining...
Debris Flows and Hyperconcentrated Streamflows
Examination of recent debris-flow and hyperconcentrated-streamflow events in the western United States reveals (1) the topographic, geologic, hydrologic, and vegetative conditions that...
Real-Time Monitoring and Flood Forecasting
An automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 150 sensors are automatically...
Heppner's User-Friendly Local Flood Warning System
The Heppner, Oregon, local flood warning system uses state-of-the-art technology with event-initiated data transmission, real-time monitoring, and automatic evaluation and notification....
Community Relations on Hazardous Waste Projects: A Successful Experience
Promoting good community relations is an integral part of hazardous waste projects. Before field investigations are conducted at a hazardous waste site, neighboring communities should...
Analysis of Alluvial Fan Flooding
Alluvial fans are estimated to cover approximately one third of the land area in the southwestern United States. Because of their relatively gentle slopes and well draining characteristics,...
A New Methodology for Modelling Water Pipe Breaks
A new methodology for modelling breaks in large diameter cast-iron water pipes is proposed. The need to consider two separate stages of deterioration (early stages with fewer breaks and...
Water System Reliability—Balance of Cost and Risk
Reliability of water distribution systems to perform adequately during stress situations is dependent both on operation/maintenance preparedness as well as the limitations of the physical...
Hazardous Waste Investigations in Residential Areas
Perspectives of a Citizen's Action Group Impacted by Hazardous Waste Contamination
Management Lessons from Engineering Failures
Engineering failures are not always catastrophic. More are due to improper management of contracts rather than actual physical failures. Some result in loss of life; most result in disputes...
Spatial Analysis of Ice Charts
Spatial approaches to ice environment modeling can not only lead to better local hazard predictions but also produce regionalizations that are useful for construction, navigation, and...
Hazardous Waste: Closing the Insurance Gap
Insurers are withdrawing from the hazardous waste field because of large claims and increased risks. Therefore, cleanup contractors are being forced to look for alternative ways to protect...
Automated Data Monitoring for Disaster Prevention
A system is now available from International Hydrological Services for use on micro-computers that will provide real-time environmental monitoring, analysis, forecasting and control. This...
Modeling of Microbially Active Soil Columns
A soil-based microbial treatment process for on-site treatement of hazardous industrial wastewaters has been developed. The indigenous microflora of the soil are supplemented by the addition...
Apportionment of Costs for Multi-Party Cleanups
A rational model was developed for allocating remedial response costs among potentially responsible parties involved in clean up of abandoned waste sites. The model takes into consideration...
True Cost Comparison of Landfilling and Incineration of Hazardous Wastes
An analysis of the 'true' costs of a series of discrete model situations representing hazardous waste management by landfilling and incineration was conducted....
