Water's New World
Potential applications of computer automation in the water industry have become increasingly apparent in the last several years. A growing number of water agencies are considering purchasing...
Highway Design in 3-D
Limitations in the flexibility and intelligence of commercial roadway design packages led Hart-Freeland-Roberts, Inc., Brentwood, TN, to write its own highway design software. From the...
Beyond Push-Button GPS
In 1993, the U.S. Air Force Space Command will complete its deployment of 24 satellites for the Global Positioning System, affording 3-dimensional positions and velocities 24 hours a day...
Appropriate Technology for Flood Warnings
Computers can help protect cities and other developed areas by enhancing flood warning systems, but smaller communities may not be able to take advantage of their sophistication. The Corps...
Taming Tornado Alley
Some structures�such as nuclear power plants�need complete protection from tornadoes regardless of the high costs of design and construction. Public facilities need protection too, but...
Expert Systems: Ready to Hit the Road?
Expert systems, programs that take the rules a person uses to solve a problem and encodes them into a computer, are starting to get serious examination from DOTs around the country. The...
Water Management Under Drought Conditions an Overview of Practices by Federal Agencies
The management of water resources under drought conditions is a diverse topic which has received added emphasis recently as a result of prolonged droughts in parts of the United States....
Signing Systems: Directional, Identity, and Graphic Systems for the Port of Long Beach
The authors have developed (in conjunction with Port staff) a revolutionary roadside communication system for The Port of Long Beach. The system includes: Renamed piers for easier understanding...
Planning, Design and Integration of a Computerized Terminal Operating System
NYK Line's new terminal at the Port of Los Angeles (photograph below) features innovative design and advanced terminal operating system integration....
Design of Marina Replacement Facilities
A majority of the waterfront design projects within the State of California are for the replacement of existing facilities since the densely populated shoreline areas are already heavily...
Proposed Seismic Design Method for Piers and Wharves
Current seismic provisions of the 1991 Uniform Building Code (UBC-91) and the 1983 AASHTO Seismic Design Specifications (AASHTO) are compared as they relate to piers and wharves. An alternate...
Design Criteria for Ferry Landings
This paper describes an ongoing research project conducted by the University of Washington Department of Civil Engineering to develop design criteria for the Washington State Ferry System....
Modern Crane Control Enhancements
Terminal operators are continually looking for innovative ways to enhance the productivity and safety of their container cranes. This paper discusses examples of control enhancements that...
Container Terminal Gates Flexible Design for a Dynamic Environment
A paper entitled 'Container Terminal Gate Efficiency Hinges on Flexibility' was presented at ASCE Ports '89 by Larry Nye of Cash & Associates Engineers. The paper summarized the...
Information Management in Water Resources: Database and GIS Integration
Historically the management and analysis of large quantities of water resources related information has been time consuming and expensive. Until recently, the use of sophisticated geographic...
Unit Hydrograph Derivation Using Geographic Information System
Geographical information system (GIS) data management and processing functions are used to develop synthetic unit hydrographs using input data consisting of digital elevation models (DEM)...
Global Change and Regional Water Resources
Global climatic changes will probably have significant effect on the utilization of regional water resources and will influence markedly the operation of water storage and delivery systems....
Predicting Water Demand in Agricultural Regions Using Time Series Forecasts of Reference Crop Evapotranspiration
Overall, it can be said that the time series model developed in this study did provide superior forecasting results for the Brawley, CA, site. This indicates that the monthly reference...
Modeling Instantaneous Residential Demands in Municipal Water Distribution Systems
A modeling scheme is proposed for simulating the intensity, duration, and frequency of instantaneous indoor water use at a single family residence. The intensity and duration of indoor...
