Reliability of Model Prediction for Pump and Treat Strategies
For the remediation of aqueous phase plumes extending over large areas simulation models are often used to predict the response of the aquifer system and the contaminant concentrations...
Numerical Modeling of Air Bubble Transport in Spillway Flow Downstream from Aerator
A simple numerical model for simulation of air bubble transport in the flow downstream from an aerator is constructed and compared with laboratory experiments. The model consists of two...
Dynamic Effect of Sediment on Dam Hydrodynamics
The dam-reservoir-foundation interaction problem has been studied by many investigators. A two dimensional model of compressible porous media is employed to analyze the dynamic response...
Numerical Modeling of Pollutant Transport in Estuaries
A robust numerical solution to the pollutant transport phenomenon in an estuary is presented. The fractional step algorithm is employed to split the physical process into convection step...
State Legislative Concerns Relative to Federal Hazardous Materials Transportation Regulation
States have increasingly asserted their authority to regulate hazardous materials transportation, in the face of inadequate and declining federal efforts. Areas of state interest include...
Risk Management in the Transportation of Dangerous Goods?The Influence of Public Perception A Discussion
In 1988, a fire at Saint-Basile-le-Grand, Quebec involving a PCB (polychlorinated biphenyls) warehouse sparked continuing controversy which included a two-week evacuation of residents....
Risk Perception and Policy Preferences of Fire Chiefs: A Survey of Hazardous Materials Issues
This paper presents the results of a survey of Connecticut fire chiefs and discusses how their perceptions of risk affect their attitudes towards risk preparedness and risk management...
Flows of Hazardous Materials Through States by Rail
This paper presents information on the tonnages of hazardous materials passing through each of the contiguous 48 states (and the District of Columbia) by rail. The quantities are estimated...
Issues in Developing Arizona's Hazmat Incident Reporting Program
The Arizona Division of Emergency Services (ADES), in cooperation with Arizona State University (ASU) - Center for Advanced Research in Transportation, and the Arizona Department of Transportation...
Developing a HazMat Incident Evaluation Program
This paper describes the Illinois Hazardous Materials Incident Evaluation Program. The history, development strategies, implementation, forms for reporting, screening and data input, and...
Canadian Database Development as a Support Tool to Transport Risk Assessment
The Risk Management Branch of the Transport Dangerous Goods Directorate supports a multi-modal safety program for dangerous goods transportation through the measurement, assessment and...
Managing Risks of Hazardous Materials Transportation in Santa Barbara County
This paper presents some potential building blocks which local jurisdictions can pursue to manage the risks associated with hazardous materials transportation (HMT). The recent experience...
Assessing Community Safety for Hazardous Materials Transport
This paper describes a computer model developed to assess the safety of a community through which hazardous materials will be transported. The model is predictive and can be used even...
A Community-Focused Routing and Siting Model for Hazardous Materials and Wastes
A model is presented that shippers, carriers and policy-makers can use to analyze routing problems for hazardous materials or routing-and-siting problems for wastes. Unlike many other...
Truck Accident and Release Rates for Hazmat Routing
Estimates of accident and release rates are essential in the conduct of risk assessments in routing studies for highway transportation of hazardous materials. Recent published literature...
Evaluation of Hazardous Material Transportation by Rail
ALK Associates Inc. of Princtron, NJ has developed a computer model, the Rail Hazardous Materials Routing System, which provides historical accident rate and population exposure statistics...
A Risk and Vulnerability Assessment Approach for Selecting Routes: Case Study of Hazardous Waste Transportation in Arizona
The study objective was to provide an approach to selecting routes to a proposed hazardous waste treatment and storage facility, based on a risk and vulnerability assessment. Probability...
Societal-Individual Risks for Hazmat Transport
Risks associated with the transport of hazardous materials by truck and rail are viewed from two perspectives: society in general and the individual residing adjacent to the route. A range...
GIS Risk Analysis of Hazardous Materials Transport
The Geographic Information System (GIS) was used to assess the risks and vulnerability of transporting hazardous materials and wastes on the Arizona highway system. This paper discusses...
StateGEN/StateNET and DOT Guidelines: Tools for Highway Routing of Hazardous Materials
Under the sponsorship of the U.S. Department of Energy Office, of Defense Programs, Sandia National Laboratories' Transportation Technology Center has developed computerized...
