Settlement Evaluation for Cap Closure Performance
Predicting short and long-term performance of a landfill cap system is a difficult task considering the generally unknown nature of the waste and magnitude and variation of settlement...
Modeling Settlements of an Existing Municipal Solid Waste Landfill Sideslope Using an Earthen Surcharge Pile
This paper discusses the results of a large-scale field compressibility test completed on municipal solid waste (MSW). The test consisted of surcharging the waste mass with an earthen...
Vacuum-Assisted Consolidation of a Hydraulic Landfill
As part of the Pier 300 42-acre site ground modification project, a field test of vacuum-assisted preconsolidation of hydraulic fill was studied. The objective of the test was to assess...
Probabilistic Observation Method for Settlement-Based Design of a Landfill Cover
Uncertainties in subsurface conditions make predicting total and differential settlement a difficult task. The Observation Method, which is commonly implemented to acquire additional knowledge...
Settlement of Dynamically Compacted Deposits
This paper compares predicted and measured settlements of deposits that were densified by means of dynamic compaction. Settlement records are presented for sites consisting of old, midage,...
Soil-Cover Success
After seven years of operation and extensive vertical and lateral expansions, owners of the Kingsland Park Sanitary Landfill, located in northern New Jersey's Meadowlands,...
Under Cover
The impermeable properties of flexible membrane liners have made them hot properties for landfill closure-cover systems. But slip-resistant clay might still be the best cover material...
Probing the Port of Los Angeles
Geotechnical investigations can uncover nasty surprises. When conducted after the preliminary design, the results can force significant and costly changes or�even worse�lengthy delays....
Flow Investigation for Landfill Leachate
A two-dimensional unsteady-state moisture flow model has been developed in order to describe the leachate flow process in a landfill. The unsteady variation of leachate mound head has...
Landfill Groundwater Monitoring Data Administration
The U.S. Environmental Protection Agency (USEPA) has promulgated regulations that require the monitoring of groundwater samples at landfill sites. The analytical data resulting from sample...
High-Tech Landfill Caps
Just as federal and state regulations detail every aspect of landfill location, construction and operation, they now detail every aspect of its design closure. A typical municipal solid...
Landfill on Screen
Engineers for a $3.7 million regional landfill in Iowa turned to computer-aided design at every project step from conceptual design through operations monitoring following construction....
Upland Reuse of Dredged Material as an Alternative to Aquatic Disposal: The Port of Oakland's Berch 30 Terminal Redevelopment, a Case Study
This paper examines the environmental and financial impacts associated with upland disposal of dredged material by discussing a recent Port of Oakland marine terminal redevelopment project....
Performance of Beach Nourishment at Hilton Head Island, South Carolina
Between May and August, 1990, approximately 2.34 million cubic yards of sand were placed along 35,000 feet of the Atlantic shoreline of Hilton Head Island, South Carolina. The project...
Beach Fill Performance at the Lido Beach, Florida, Groin
Lido Beach on the Gulf of Mexico in Sarasota, Florida traditionally has been used as a placement area for sand dredged from the adjacent New Pass federal navigation project. At the end...
A Review of Fluid Movement in Compacted Clay: The Case of Macropore Flow
In constructing natural hydraulic barriers to infiltration, a typical design is one founded on the use of layers of compacted clay. Unfortunately, in analyzing the hydraulic performance...
Non-Intrusive Crack Detection in Clay Landfill Cover Liners
Laboratory and field studies were conducted to demonstrate that the azimuthal variation in electrical resistivity can be used to indicate the presence of cracks in clay systems. Laboratory...
A Solid Waste Solution
Burgeoning growth and diminishing landfill capacity have been propelling Broward County, Fla. toward a solid-waste crisis. The county, located along Florida's southeastern...
Real Time Forecast of Landfill Leachate Flow
A computer model was written to describe the generation of landfill leachate due to large precipitation events. The landfill is described as a multi-layer system, each layer having its...
Orange County Florida Landfill Dilute Leachate Wetland Treatment and Restoration System
The Orange County Landfill began operation in 1971 as an EPA demonstration project for the purpose of defining landfill operations in high groundwater table areas. To prevent groundwater...
