Sensitivity of Flow and Salt Transport to Uncertainties at Open Boundaries: A 3-D Experience
Understanding the transport due to tidal and sub-tidal exchange processes enables many environmental issues in estuarine systems to be addressed. To achieve this goal, a reliable numerical...

Pollutant Transport Modelling in Large River Plumes
The Niagara River plume in Lake Ontario and the Fraser River plume in the Strait of Georgia are of similar spatial dimensions, and arise from rivers with comparable discharge. Both rivers...

Approximation of Convective Processes by Cyclic AOI Methods
Convective or advective processes play a role in many models for civil engineering applications. For example in transport equations, in hydrodynamic equations or wave energy equations....

The Last Freeway
Ever since what's now known as the Pasadena Freeway was completed in 1940, Los Angeles has been synonymous with the freeway�first with the ease and speed of transport it represented...

A European Road Comes to the U.S.
From Sept. 7 to Sept. 22, a group of 21 federal and state transportation officials and industry representatives participated in the European Asphalt Study Tour, traveling the roads of...

Housing Chernobyl Relocatees
The April 1986 explosion of the Chernobyl Nuclear Power Plant Reactor 4 in northern Ukraine Commonwealth spread nuclear contamination assisted by southerly winds across hundreds of miles...

Opportunities for Improved Transportation Planning
The approaches, technical procedures, and analytical methodologies utilized for urban transportation planning need to be improved if the intent of the 1990 amendments to the Clean Air...

Delaware Valley Regional Planning Commission's Anticipated Response to the Clean Air Act Amendments of 1990
By virtue of its charter to provide continuing, cooperative and comprehensive planning, the Delaware Valley Regional Planning Commission (DVRPC) has a commitment to adopt and maintain...

The Clean Air Act: Opportunities for the Transit Industry
The 1990 Federal Clean Air Act Amendments (CAAA) have opened up new opportunities for transit agencies, especially those in large urban areas with the worst air pollution problems. The...

Integrated Software for Transportation Emissions Analysis
As the air pollution problem in the major metropolitan areas of the United States has increased, new interest has emerged for greater accuracy in the estimation of emissions from mobile...

Travel Markets: An Approach to TCM Effectiveness Evaluation
This discussion paper describes a new approach to TCM evaluation using a travel market concept to classify trip types based on expected elasticities to various TCMs. Conventional trip...

Evaluating the Effectiveness of Transportation Control Measures for San Luis Obispo County, California
The San Luis Obispo Air Pollution Control District has developed simple techniques to estimate emission reductions from various Transportation Control Measures. Accurate emission estimates...

Responding to Public Opinion About Cumulative Long-Term Risks: Analysis and Communication of Risks from Climate Change and Hazardous Waste Sites
Public reactions to cumulative, uncertain, and long-term (CULT) risks pose particular problems to risk communicators. Low-magnitude and low-probability risks (e.g., living next to a hazardous...

Conflicts in Health and Safety Matters: Between a Rock and a Hard Place
Constraints on time and resources influence the public sector as strongly as they influence our personal lives. Experience teaches us that our desires must be tempered by hard realities....

Aversion to Epistemic Uncertainties in Rational Decision Making: Effects on Engineering Risk Management
When faced with epistemic uncertainties in a decision problem, subjective expected-utility theory (SEU) implies that the only relevant characteristic of these uncertainties is the mean...

Controlled Braking on Uneven Roads
The braking process of a passenger car may be influenced by a large number of variables relating to driver, vehicle, brake system, tire-road interaction and ambient conditions. Because...

Probabilistic Evaluation of Redundancy of Bridge Structures
Redundancy of bridge structures and methods to evaluate redundancy are reviewed in this paper. A method to measure redundancy based on the existing theories of probability as related to...

Pre-Envelope Covariance Differential Equations
The problem of predicting the safety of structural systems subjected to random loading arises in may engineering applications. In this framework the envelope process plays an important...

Critical Issues Related to a Combined Probabilistic Numerical Analysis of Contaminant Transport in Porous Media
Reliability algorithms provide attractive alternatives to Monte Carlo simulation and stochastic perturbation approaches for probabilistic analysis of contaminant transport in porous media....

A Fatigue Reliability Model for Railway Bridges
A fatigue reliability model is described for safety evaluation of steel railway bridges. The model is a function of six independent random variables and can accommodate different types...
