New York Bight Three-Dimensional Water Quality Model
The numerical modeling technology developed for Chesapeake Bay was applied to the Middle Atlantic Bight extending 550 km form Cape May, NJ, northeasterly to Nantucket Island, MA, and extending...
Hydraulic Performance of a Flexible Curtain Used for Selective Withdrawal ? A Physical Model and Prototype Comparison
Reclamation (U.S. Bureau of Reclamation) studied a 1:120 scale undistorted density stratified physical model to develop a lightweight flexible curtain barrier that would control the outflow...
Flow Diversion in a Steep, Coarse-Bed Stream
A case study is presented of the hydraulic design of a diversion structure in a high velocity, coarse bed streamcourse. Mill Creek, a tributary to the Upper Jordan River in the southern...
Thermal Shielding in Continuous Span Composite Slabs
The increasing popularity in Europe of composite slabs with cold-formed steel decking has underscored the need to improve calculation rules for the fire resistance. Existing rules have...
Application and Recent Development of a Numerical Model for Composite Beams with Partial Shear Connection
This paper deals with numeric analysis of composite steel and concrete beams for loads up to the ultimate beam capacity. Two versions of a numerical model are presented addressing such...
Real World Applications of Pipeline Leak Detection
This paper covers various leak detection methodologies and how they are integrated into the Williams Pipe Line system. Special emphasis is given to the dynamic model method of leak detection...
Predictive Model Aids in Development of Systemwide Rehabilitation Program
Effective management of urban infrastructure requires accurate assessment of system-wide condition. Working with the City of San Jose, CH2M HILL has developed a computer model to provide...
Proactive Odor Control Using Computer Modeling
The City of Los Angeles (City) is currently designing the East Central Interceptor Sewer (ECIS) as a major relief sewer. The pipeline will convey wastewater flows that originate upstream...
Innovations in the Development and Expansion of Intermodal Facilities
The intermodal industry is a dynamic one, with a long history which has undergone profound change since the introduction of containerization only 30 years ago. Today, change continues...
Trip Rates Adjustments for Impact Assessment and Congestion Management
Evidence that all urban trips are not equal and that trip rates need to be adjusted to reflect the differential contribution of trips to traffic loads and congestion is presented. Adjustments...
BMS Modelling of Bridge Stock Performance
A computer-based Bridge Management System, BMS, was designed in Finland by the Finnish National Road Administration (FinnRA) to assist in high level bridge policy, long-term planning and...
Seeing the Future: Changing Highway Engineering Practice Over the Next 10 Years
The computer age is here, and the more a highway engineer knows about computers, the better. This really symbolizes the direction highway engineers are headed - into a high-tech world...
Influence of Lateral Wind on Driving on Offshore Bridge
The Honshu-Shikoku Bridges are a system of highways crossing over the sea, where cross-winds variously affect vehicle behaviour. This is the intermediate report on the surveys aimed at...
Computer-Aided Liability
Civil engineers are using computers more than ever to help them streamline analysis and design, boost productivity and cut costs. Often they rely on mass-marketed software such as Autodesk...
The Application of 3 Dimensional Geographic Information Systems in Geotechnical Earthquake Engineering
The requirements and needs of Geographical Information Systems (GIS) in geotechnical earthquake engineering are described, and the use of such system in New Zealand is discussed. We have...
Digital-Image-Based Computer Modelling of Cement-Based Materials
Understanding the relationships among materials, processing, microstructure, and properties is critical in improving material design. This paper outlines an approach for furthering this...
Video Modeling: A New Paradigm for Reproducing Complex Engineering Artifacts on Computer
This paper introduces a novel approach for automatically creating accurate computer models of existing, physical artifacts. Based on the projected silhouettes of the object, when viewed...
A New Three-Dimensional Modeling Technique for Studying Porous Media
A new three-dimensional technique for modeling the micro-structure of porous media is proposed. On the basis of measurements of characteristics made using thin sections of porous media...
Image Analysis for Interparticle Contact Modeling
Two dimensional photoelastic elements (disks or ellipses) are used as models for studying granular material behavior. The required observations include accurate continuous measurements...
Image Enhancement: Application to Geotomography
Image enhancement complements geotomographic reconstruction in the rendering of better images. In this paper, available image enhancement techniques are reviewed. Emphasis is given to...
