Introduction to Immersed Tube Tunneling Symposium
Today's Symposium on Immersed Tube Tunneling is a continuation of a series of papers that began at Construction Congress '89 with discussion of mined tunnel subaqueous...
Constructability?Washington State Highways
During the last decade, efforts were directed towards improving constructability of highway design at Washington State Department of Transportation (WSDOT). This paper briefly summarizes...

State and Local Issues in Transportation of Hazardous Waste Materials
Towards a National Strategy
This proceedings contains papers presented at the specialty conference State and Local Issues in Transportation of Hazardous Materials: Towards a National Strategy held on May 14-16, 1990...
Building Green
Some scientists say polystyrene insulation may be responsible for up to 40% of the ozone depletion caused by CFCs. That's only one reason why construction and design professionals...
The Effect of Surface Films on Concentration Fluctuations Close to a Gas/Liquid Interface
Modeling of gas/liquid mass transport requires knowledge concerning the behavior of near-surface concentration fluctuations at clean and film-covered gas/liquid interfaces. Previous measurements...
Hydrodynamics and Mass Transfer on a Moving Drop of Water
The fluid dynamics and mass transfer associated with moving water drops are examined. In the first part, numerical solution of the transient hydrodynamics around and inside a drop falling...
Regional Estimates of Gas Transfer Using an Airborne System
The aircraft-based eddy correlation technique was recently used to obtain regional observations of transfer processes of sensible and latent heat as well as carbon dioxide over wetlands...
Oxygen Transfer in Turbulent Shear Flows
Oxygen transfer equation for the air-water two-phase aeration region of turbulent shear flow in a vertical pipe is derived. Dimensionless variables significant in characterizing the transfer...
Correlation of Fractional Foam Coverage with Gas Transport Rates
Because breaking waves are believed to increase the flux of gases across the air/sea interface, it may be possible to correlate air/sea gas transport velocities with whitecap coverage....
Experiment on the Efficiency of an Aspirator-Blower Type Aerator
An aspirator-blower type aerator was designed and tested successfully for small lake application. The experiment showed that significant amount of air flow can be generated by the aspirator...
Taller Tunnels
Between 1984 and 1991, Shannon & Wilson, Inc., Seattle, designed renovation programs for more than 25 mi of tunnels for four western railroads. We performed all of this work under...
Civil Engineering Applications of Remote Sensing and Geographic Information Systems
This proceedings includes 41 of the papers presented at the Second National Specialty Conference on Civil Engineering Applications of Remote Sensing and Geographic Information Systems...
Seismic Design and Performance of Railroad Bridges
Damage to railroad bridges during earthquakes in the United States and Japan is summarized. Research tasks are outlined to develop seismic design and retrofit criteria for railroad bridges....
Seismic Practices for the Air Transportation System: Evolution and Needs
The seismic performance of air transportation systems is reviewed. The evolution of seismic design criteria and practices for major air transportation system elements is discussed. The...
Seismic Vulnerability Assessment of Bridges on Earthquake Priority Routes in Western Kentucky
This paper discusses the current conditions of 203 bridges on the priority routes in Western Kentucky and their vulnerabilities to earthquakes. A span-loss type of bridge collapse due...
Engineering Tactics on Lifelines Safety Against Earthquakes
Effects of sediment-filled valley on seismic ground motions have become of major interest in earthquake engineering throughout this decade. This paper presents interesting phenomena of...
Automatic Vehicle Classification System
China has recently completed a number of freeways, all of which were financed in part by the Ministry of Communications and local governments and in part by loans from the World Bank,...
Analysis of Automatic Vehicle Identification Technology and Its Potential Application of Florida's Turnpike
The Florida Department of Transportation contracted with the Center for Urban Transportation Research (CUTR) at the University of South Florida to conduct an analysis of automatic vehicle...
Analysis of Roadside Equipment and Central Facilities for Innovative Driver Information and Traffic Control Systems
Following a top down analysis of a selected set of innovative RTI functions, we identify in this paper the requirements and characteristics of the roadside equipment and central installations...
