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...
Lapsize Computers and Local Pavement Management
The purpose of this study is to examine the use of a portable computer, the GRIDcase Plus, in local pavement management. A software program in BASIC is developed to run on the GRID, to...
A Microcomputer Methodology for Parsimoniously Structuring a Set of Activities
The paper develops a systematic methodology to aid in the identification and rapid structuring of a system of activities. In essence, the user is asked to supply only the names of the...
Estimating Toll Diversion for Beltways
The proposed E-470 beltway is a 48-mile circumferential highway which will connect major public and private developments east of the Denver metropolitan area as well as the new Denver...
Transit Scheduling Using Computer Graphics
Graphical scheduling has been very popular throughout the world, but until recently, has not been available for a computerized scheduling system. Computerized graphical scheduling systems...
GRREATdB - GRaphic Roadway Editor and Analysis Tool
This paper describes the development and use of a tool to link textual databases to road network-based interactive graphics. Advantages of the system are discussed. The GRREATdB program...
A Survey of Three-Dimensional Numerical Estuarine Models
This paper surveys the existing 3-D estuarine hydrodynamic and solute transport models by a review of the commonly used assumptions and approximations, and by an examination of the methods...
Application of a Boundary Fitted Coordinate Hydrodynamic Model
A three-dimensional, boundary-fitted hydrodynamic model was applied in a two-dimensional, vertically-averaged mode to predict the tidal circulation in Mt. Hope Bay, a small estuary located...
Evolution of a Three-Dimensional Curvilinear-Grid Hydrodynamic Model for Estuaries, Lakes and Coastal Waters: CH3D
Traditional finite-difference models of estuarine, coastal and lake hydrodynamics and transport use rectangular Cartesian grids in the horizontal directions. In order to accurately represent...
Long-Term Fate of PCB Contamination in the New Bedford Harbor, Massachusetts, System
The transport and fate of polychlorinated biphenyls (PCBs) at the New Bedford Harbor Superfund site is modeled using a three-dimensional hydrodynamics and sediment-contaminant transport...
Circulation and Transport Modeling in New Bedford Harbor
Three-dimensional hydrodynamics and mass transport were simulated in the New Bedford Harbor, Massachusetts, area in support of a combined sewers/sewage outfall facilities planning project...
Application of Particle Tracking Model for Ocean Outfall Siting in New Bedford, Massachusetts
PACE, a particle tracking model, was used to assist siting studies for an ocean outfall to be built in conjunction with the City of New Bedford's proposed new secondary wastewater...
Hydrodynamic Modeling on Vertically Mixed Bays
Extensive model-data comparisons of sea surface elevations and vertically-averaged velocities are performed on the Peconic Bays Estuary, New York, a system of interconnected bays where...
CSO Induced Circulation in Marine Tributaries
Pulses of freshwater flow to estuarine tributaries from combined sewer overflows (CSO) create short duration intense salinity stratification in the tributaries. An accurate assessment...
Development of a Three-Dimensional Hydrodynamic Model of Chesapeake Bay
A time-varying 3D numerical model of Chesapeake Bay has been developed to provide flow fields and vertical eddy diffusivities to a 3D water quality model of the bay. The water surface,...
Modeling a Wind-Mixing and Fall Turnover Event on Chesapeake Bay
A three-dimensional (3D) numerical hydrodynamic model of Chesapeake Bay has been developed. Results from application of the model to one of the three data sets employed in the verification...
