Permeability of Compacted Clay Liners in Laboratory Scale Models
Experiments conducted in flexible wall permeameters have shown that the permeability of a soil sample is dependent on the size of the specimen tested. The permeability was found to decrease...

Geotechnical Properties and Landfill Disposal of FGD Sludge
Extensive test data from more than a decade of research are compiled on the geotechnical engineering properties of flue gas desulfurization (FGD) sludges with emphasis on double alkali...

Quality Assurance Monitoring of a Large Clay Liner
The Keele Valley Landfill at Maple, Ontario, consists of a 99 ha (245 acre) facility to serve the Metropolitan Toronto area. The landfill is located in a former sand and gravel pit, with...

Hydrocarbon Refining Waste Stabilization for Landfills
Mobile pollutants are generated in a landfill as a function of the waste properties and the response of the deposit to the in-situ stress, climate and biochemical conditions. Release of...

Water Treatment Plant Sludge as Landfill Liner
Chemical sludge is produced in large quantities during the water treatment processes. The present regulations pertaining to the disposal of solid wastes impose many constraints on any...

Environmental Monitoring and Observations Before and During Excavation of a Landfill in Owatonna, Minnesota
A Minnesota landfill inactive since 1962 was excavated in 1985 to prepare the site for construction of a new waste water treatment plant. The excavation refuse was disposed of in nearby...

Modelling of Contaminant Transport in Clays Via Irreversible Thermodynamics
This study develops a model for the analysis and prediction of contaminant transport in soils using principles of irreversible thermodynamics. The developed model includes five parameters...

Soil Improvement
A Ten Year Update
Since the publication of Soil Improvement?History, Capabilities and Outlook after the Annual ASCE convention in Philadelphia in 1976, a dramatic growth in certain soil improvement techniques...

Seismic Analysis of Safety-Related Nuclear Structures and Commentary on Standard for Seismic Analysis of Safety Related Nuclear Structures
This standard provides requirements for performing analyses to obtain design information which will lead to the reliability of structures under a severe earthquake. The goal of this standard...

Use of Vibration Measurements in Structural Evaluation
Over the past decade the capabilities for vibration measurements and analysis have advanced significantly. It is now a routine procedure to be able to measure natural frequencies of structures...

Engineering Aspects of Soil Erosion, Dispersive Clays and Loess
This collection of papers deals with selected engineering aspects of soil erosion, dispersive clays and loess. Two types of erosion are considered?surface and subsurface (piping)?with...

The Mexico Earthquakes?1985
Factors Involved and Lessons Learned
This publication reports initial results of study of the 1985 Mexico earthquake, one year after the event. The findings present sufficient depth of analysis to provide an understanding...

Planning by Database
Denver's Stapleton International Airport cannot handle the growing volume of air traffic and will be replaced by an entirely new $3 billion Denver Metropolitan International...

Hydraulic Structures on Piles
Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses...

Consolidation of Slurried Soils
This paper describes the use of large strain consolidation theory and centrifugal modelling to study the consolidation behavior of slurries. Laboratory testing of the slurry is needed...

Suspended Material Transport at New Bedford, MA
Evaluation of suspended material migration was a task in a study of sediment-associated contaminant migration. New Bedford Harbor is a vertically well-mixed, shallow estuary with little...

Update: Fluidization for Tidal Channel Maintenance
Flow emanating from perforations in a pipe under a non-cohesive media, such as sand in the coastal environment, can fluidize the overlying media. The fluidized sand can be readily moved...

Modeling Sediment Yield Affected by In-Stream Sand Mining
Sediment yield refers to the amount of sediment having passed a given river section for a specified duration. While sediment will be stored in the borrow pit, it will also be depleted...

Modeling Materials for Protecting Earth Weirs
This paper reports laboratory experiments on various materials used to protect earth weirs. Dumped rock, gabion mattresses, and shaped blocks on a gravel layer were subjected to high velocity...

Reinforcement of Steep Grassed Waterways
A collaborative research program has been undertaken in the UK to develop guidelines for the use of various proprietary reinforcement systems to enhance the erosion resistance of grass...
