A Watery Grave
Subseabed disposal may be the most acceptable means of dealing with radioactive wastes. Land disposal sites are difficult to find and politically difficult to use. Little research has...
Leachate Migration from a Solid Waste Disposal Facility Near Biscayne National Park, South Florida (
Leachate from the Dade County Solid Waste Disposal Facility (SWDF) is migrating to the east (seaward) and to the south from the currently active disposal cell. Water levels and ground-water...
Vertical Shelter From Hurricanes: Risk Perceptions and Politics
To reduce risks posed by high hurricane evacuation times, vertical shelters have been proposed. This paper presents a preliminary assessment of key decision makers' reactions...
Application of an Ecosystem/Water Quality Model as a Tool for Managing Estuarine Water Quality
A laterally averaged two-dimensional computer model was developed to simulate the hydrodynamics, transport, and ecosystem dynamics of Budd Inlet, a small partially mixed estuary located...
Site Characterization for Waste Disposal
Site selection is one of the key decisions in waste management. Site selection involves a conflict analysis which considers various engineering factors including geotechnical, as well...
Design of Geosynthetic Systems for Waste Disposal
Geosynthetic materials (consisting of geotextiles, geomembranes, geogrids and geocomposites) are currently being used in large amounts to contain solid wastes in landfills, surface impoundments...
Field Measurements of Landfill Surface Settlements
The Collier Road Landfill, located in southeast Michigan, has been accepting industrial and muncipal solid waste since the late 1960's. This existing landfill encompasses...
Evaluation of Compacted Inert Paper Solids as a Cover Material
The following paper presents the results of a laboratory test program which focused on compacted sludges or inert paper solids (IPS) as recommended cover (cap) material over existing IPS...
Risk Assessment and Public Policy
A governmental official charged with making solid waste policy should be careful not to allow the public policy issue to be defined as the determination of the acceptable level of risk...
Modeled Effects of Hydraulic Mixing Devices on Reservoir Water Quality
A two-dimensional reservoir water quality model was used to evaluate effects of hydraulic mixing devices on release and water quality. Seasonal simulations of Douglas Reservoir water quality...
Dispersal of Dredged Material Disposal Plumes
An empirical model describes dispersal of dredged material disposal plumes in an urban estuary, Central Long Island Sound, during spring of 1983. The model uses in situ current meter data...
Garbage: Cogeneration's Third Dimension
Burning garbage or refuse derived fuels (RDF) is becoming more common in cogeneration plants being constructed in the U.S. The three-for-one concept turns one fuel into two products (steam...
Dioxin and Resource Recovery
The 1987 ASCE Dioxin and Resource Recovery Symposium was held at the New York Hilton Hotel, New York on February 10, 1987. The conference served as an opportunity to assess the issue of...
Turbine Efficiency Loss Associated with Draft Tube Aeration
Draft tube aeration is one method for improving the dissolved oxygen content of hydroelectric discharges. A simple analytical procedure is presented for estimating the loss in turbine...
Frazil Ice Problems in Intakes at Montreal
Intakes located in reaches of the St. Lawrence River that stay open all winter can be subjected to frazil ice formation for nearly three months. The City of Montreal intake is a key example...
Permafrost: A Suitable Landfill Containment Barrier
Ice-rich permafrost is a suitable medium for the containment of wastes. The combination of frigid dry Arctic climate and the impermeability of ice-cemented permanently frozen ground can...
Interactive CAL Modules for Mechanics of Solids
Traditionally the basic engineering course in 'Mechanics of Solids' has proven to be a challenge to both the students and faculty, for although the fundamental...
The Optimization of Nitrification and Denitrification in Plug-Flow Activated Sludge Systems Treating Municipal Wastestreams
Most conventional plug-flow activated sludge plants experience nitrification, particularly during higher temperature conditions. Under these circumstances, additional power is required...
Comparison of Two Audits for Electric Utilities
Two case studies on environmental audits were examined to illustrate the differences between the comprehensive audit and a focused audit. The differences in audit team composition, technical...
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...
