Cleaning Up: The Second Decade
Endless media coverage and a high level of public anxiety make it seem as though the U.S. has been attempting to clean toxic waste sites for decades. In fact, the 1980s were our first...
Corps of Engineers Drought Management Experiences
The drought of 1988-89 was one of the most severe on record for many regions of the United States. Its severity can be measured in terms of the areal extent of hydrologic impact, the record...
U.S. Tackles Leaking Tanks
Regulations to deal with leaking underground storage tanks have been in force since 1984 and deadlines for compliance began in 1989 for tanks installed before 1969. The Environmental Protection...
Rochester Stops the Deluge
After a slew of stopgap waste-treatment plants failed to solve Rochester's chronic storm water and sewage overflow problem, city officials changed direction in the late 1960s....
Seismic Design of Liquid Storage Tanks
Originally published in: Journal of the Technical Councils, ASCE, TC1, April 1981...
Geosynthetic Shields For Dams
A series of large dams in Europe, waterproofed by geosynthetics, may become U.S. prototypes. In Europe, the faces of more than 30 large dams now contain geotextiles and geomembranes. In...
Evaluation and Remediation of Construction Defects in Tilt Wall Panels
Both the surface appearance and structural safety were of concern to the Owner of a five year old warehouse structure that was experiencing delamination of tilt-up wall panels. Delamination...
Vibration Control Damper Using Sloshing of Water
The objective of this study is to develop a method of reducing wind-induced vibration of long-period structures utilizing sloshing of water in tanks added to the upper part of the structures....
Seismic Isolation of Storage Tanks
There has been a significant amount of research activity over the past decade on the seismic design of storage tanks. The seismic design issues and limit states are quite complex due to...
Seismic Large Amplitude Liquid Sloshing?Theory
The sloshing phenomenon in seismically-excited, rectangular, liquid storage tanks is addressed. In particular, a semi-analytical method to study the effects of large amplitude sloshing...
Buckling Criteria for Earthquake-Induced Overturning Stresses in Cylindrical Liquid Storage Tanks
Perhaps one of the most common forms of seismic damage to cylindrical liquid storage tanks made out of steel is buckling of the tank wall due to vertical overturning stresses. Buckling...
Big-Scaled Tilt Test on Uplifting Behavior of Oil Storage Tanks
The authors conducted a series of static tilt tests using a very big model with the full similitude in order to investigate the uplifting behavior of large-scaled tanks. The model was...
Static Tilt Analyses of Uplifting Cylindrical Tank
This paper describes the general method adopted for predicting the static tilt performance of cylindrical liquid storage tank that is free to uplift. In the analysis described here, the...
Special Bedrock Conditions and a Foundation Project in Greater Boston
In the greater Boston area the argillite bedrock and/or the overlying glacial till provide suitable support for a wide range of foundation systems, including high capacity end-bearing...
Using Borosilicate Glass as a HLW Storage Medium
There is growing concern over the quality of present high level waste management techniques. Instances of nuclear accidents and contamination at nuclear waste sites in the United States...
Closure of Hazardous Surface Impoundments and Creation of an On-site Permanent Disposal Facility?A Case History
Remington Arms Co. is currently undertaking a RCRA closure program for nine surface impoundments in Lonoke, Arkansas. The impoundments contain a variety of listed hazardous wastes from...
Decision Framework for Assessment of Leaking UST's
A computer-based environmental planning tool, designed to help mitigate the environmental problems associated with leaking underground storage tanks (UST) is presented in this article....
Design of Solidified/Stabilized Sludge Landfills
Rehabilitation of highly moist, compressible, and heavy metal-containing wastewater treatment sludges for final disposal in a landfill setting requires consideration of several factors....
The Distribution of PCB Contaminated Sediment in the Kalamazoo River Valley, Michigan
Heightened environmental awareness beginning in the 1970s focused upon lowering contaminant levels in the Kalamazoo River system through the improvement of water quality. The Michigan...
Design and Implementation of a Risk-Based Remedial Action Program for Underground Tank Removal at a Dioxin-Contaminated Site
