Guidelines for Seismic Evaluation and Design of Petrochemical Facilities
These guidelines are intended to provide practical recommendations on several areas which affect the safety of a petrochemical facility during and following an earthquake. In the area...
Wind Loads and Anchor Bolt Design for Petrochemical Facilities
Current codes and standards do not address many of the structures found in the petrochemical industry. Therefore, many engineers and companies involved in the industry have independently...
Los Angeles Metro-TBM Starter Tunnels-Mixed Face Conditions
Twin TBM starter tunnerls with mixed face conditions were successfully mined by roadheader with steel rib and shotcrete initial support beneath the Hollywood Freeway. Tunneling and total...
Degradation of Natural Building Stone

The Right Tooele for the Job
Parker describes how the nation's largest chemical munitions destruction facility was designed and how it will operate. The U.S. Signed on to the Chemical Weapons Convention...
Chemical Grouting
Technical Engineering and Design Guide, as adapted from U.S. Army Corps of Engineers, No. 24. This manual provides information and guidance for the...
Ground-Water Treatments Gain Ground
Ground water is the main source of the nation's public water supplies and is also used extensively for agricultural and industrial purposes. Yet our reserves are constantly...
Leachate Chemistry: Its Implications for Clogging
The clogging of leachate collection systems is controlled by interrelated mi and chemical phenomena. Mesocosms containing landfill materials and simulating leachate collection were infiltrated...
Pilot Testing of a Zero-Discharge Treatment Process
As environmental regulations become more stringent, pulp and paper mills are investigating alternatives to conventional biological treatment and discharge of effluents into receiving waters....
Use of SALQR Optimization in Large Aquifer Cleanup
A modified form of Differential Dynamic Programming (DDP), called Suc cessive Approximation to a Linear Quadratic Regulator (SALQR), is used to compute optimal policies for remediation...
A Graphical Environment for Multi-Dimensional Surface Water Modeling
Recently the Engineering Computer Graphics Laboratory of Brigham Young University in conjunction with the U.S. Army Engineer Waterways Experiment Station and the Federal Highway Administration...
Analysis of Bank Stabilization in Steep Complex Streams Using A Two-Dimensional Model
In cases where the channel is fairly uniform, and not divided, one-dimensional hydraulic models, such as HEC-2, generally give adequate results for scour evaluations and bank protection...
Comparative Simulation of Oil Weathering
Oil spills in the aquatic environment, an unfortunately more and more common occurrence, cause contamination effects which negatively impact water quality, health of ecosystems and water...
Risk Analysis of Drinking Water Treatment and Supply Facilities Handling Highly Hazardous Chemicals
Due to increasing public concern of risks from handling highly hazardous chemicals at various facilities, a number of state regulatory agencies, including the State of California, have...
Geochemical Modeling of Lead in Vadose Zone
In recent years, researchers have used multicomponent reactive transport models to study the mobility of potentially toxic heavy metals in the subsurface. In this study, such a mathematical...
Health Risk Sensitivity to Variable and Uncertain Parameters
A methodology is presented that attempts to quantify the effects of individual variability and parameter uncertainty in a groundwater-driven health risk assessment. Two modeling approaches...
The Importance of Water Depth for Sparger Performance
As part of TVA Hydro Modernization Program, the two 59-year old Francis turbines at Norris Dam have been upgraded with new units. In conjunction with TVA's Reservoir Releases...
The Environmental Valuation Reference Inventory (EVRI) for Water Related Benefits Transfers
Managing our water resources requires knowledge not only of flows, water chemistry and aquatic life, but also of the various uses and economic values that humans place upon the water....
Recover Inorganic Solids from Obsolete Propellants
A feasible process was developed to recover inorganic solids (energetics and metallic fuel) from obsolete polyurethane-based propellants in order to solve their associated long-term disposal...
Specification of Cu, Pb and Cr in Contaminated Sediment Effected by pH
Sediment was sampled from a contaminated river. Sequential extraction was applied to determine the speciations of Cu, Pb, and Cr in the sediment with varied pH (5?9), and the redox potential...
