Unification in Estimation of Confidence Intervals
One area of future development needs in technology pertaining to surface runoff hydrology is the unification of techniques used by govermental agencies in the estimation of surface runoff...
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...
Two Dimensional Analysis of Strain Localization with Nonlocal Continuous Damage
This paper addresses the problem of damage localization from a theoretical stand point with a nonlocal model. Conditions for non uniqueness of the rate equations of equilibrium are derived...
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...
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...
Micro-Damage Process Model for Polycrystalline Ice
This paper presents a micro-damage process model for freshwater polycrystalline ice deforming at the high end of the ductile-to-brittle transitional domain of strain rated. Damage is attributed...
Strain Rate Effects on Pressuremeter Testing
This paper discusses the effect of strain rate on the cavity expansion problem and pressuremeter test. A cuboidal shear device, CSD, was used to perform pressuremeter strain path tests...
Testing the Limits
More than 100,000 bridges in the U.S. are considered structurally deficient and in need of posted load limits or repair. As the number continues to mount, engineers search for a better...
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...
