A Microcomputer Program for Roadway Lighting Design
LUMSIM is a knowledge-based design program that uses operator input data and design criteria to select the most economical lighting system. The initial input parameters include pavement...

Traffic Simulation and its Graphic Presentations
A computer simulation program for traffic signal timing design was developed. The program can provide some appealing graphic presentations not only of input data but also of output results....

Computer Aided Design of Traffic Signal Systems
Computer Aided Design and Drafting (CADD) has traditionally been the domain of powerful and expensive computers. Personal computer technology, however, is rapidly changing this trend by:...

MECHOD: A Mechanistic Overlay Design Program for Flexible Pavements
This paper presents a fully mechanistic asphalt overlay design procedure for use on microcomputers. The procedure is based on fundamental characteristics of pavement layer properties and...

A Microcomputer Based Pavement Design Program
This paper describes a newly developed pavement design program. The performance of a number of pavement structures are projected over the analysis period. Structurally adequate designs...

Interfacing Pavement Management and Design Process
Pavement management systems coordinate all the activities required to provide pavements for the traveling public in a cost efficient manner. Information for the pavement management system...

Modeling and Data Uses in Hydraulic Transport Investigations, New Bedford Estuary, Mass.
Field measurements, laboratory tests, and models were used together to make transport predictions for the sediments and dissolved materials which would be released by proposed dredging...

Resistance Coefficient in a Tidal Channel
In applying a numerical hydrodynamic model to the tidal channel-lagoon complex around Great Sound, New Jersey, it became apparent that the model guidelines for the resistance coefficient...

Circulation Between I-664 Channel Islands, James River, Virginia

The Chesapeake Bay Hydraulic Model: Construction, Operation and Verification
This paper discusses significant aspects of the construction, operation, verification and testing at the Chesapeake Bay Hydraulic Model which was operational from May 1976 to August 1984....

Technical Work on Flexible Pipe/Soil Interaction Overview?1990
Research in the laboratory and field have been ongoing for the past seventy years on flexible pipe/soil interaction. Virtually all of the early work was done on steel pipe. During the...

Pipeline Design and Installation
The proceedings of the International Conference on Pipeline Design and Installation, held on March 25-27, 1990 in Las Vegas, Nevada, presents information on all aspects of pipeline design...

Morphology and Roughness in the Hydraulics of Large Bed Element Channels
The evolution of natural steep channels is a function of two factors in accordance with the principle of least action: flow distribution in the channel and terrain geomorphology. Large...

Development and Implementation of the Wekiva River Basin Regulatory Program in Central Florida
The St. Johns River Water Management District developed a comprehensive surface water management program for the basin. Between 1987 and 1989 the District implemented basin specific design...

Biodiversity in Riparian Communities and Watershed Management
Riparian communities are demonstrated to be regional centers of biodiversity and biomass. Examples are taken primarily from bird and lizard communities in the Southwest, since these vertebrates...

Stream Bank Stability Prediction for C6 Stream Type Reconstruction
A hydraulic model investigation will be conducted to evaluate the effects of root system characteristics of three meadow plant communities on simulated bank erosion. The test will determine...
