Boundary Fitted Estuarine Water Quality Model
A two-dimensional, vertically-averaged boundary fitted coordinate pollutant transport model was developed for application to estuarine and coastal sea regions. The governing convective-diffusion...
Advection-Diffusion Calibration of Dissolved Oxygen
Modifications of J.J. Leendertse's water-quality model for improving calculations of dissolved oxygen concentrations in Jamaica Bay, New York, are discussed. Changes to the...
Contaminant Loading from Fox River to Lower Green Bay
The heavily industrialized lower reach of the Fox River, downstream of the DePere Dam, and lower Green Bay, Lake Michigan, are modeled. Hydrodynamics and contaminant transports to the...
Three-Dimensional Modeling of Pollutant Transport
A numerical model for pollutant transport in coastal waters has been developed in x-y-z-t space. The simplicity of a fixed Eulerian mesh and a computationally efficient Lagrangian approach...
Model Comparisons of Oyster Recruitment in Delaware Bay
A second order particle trajectory model using surface currents from a three-dimensional model of Delaware Bay was run for a period equivalent to the larval stage of the oyster C. virginica...
Data-Collection Program for Pamlico River Estuary Model Calibration and Validation
An investigation is being conducted to collect and interpret continuous records relating to the flow characteristics of the Pamlico River Estuary, North Carolina, and to calibrate and...
Recent Progress on Hydrodynamic Modeling of San Francisco Bay, California
A hydrodynamic modeling study of the effects of freshwater inflow on circulation and mixing in San Francisco Bay has been underway since 1985. This paper describes the multidimensional...
Comparison of Computed and Observed Velocities at Three Estuarine Sites
The Generalized, Longitudinal-Vertical Hydrodynamic and Transport model (GLVHT) has been applied to the Patuxent River estuary, the Raritan River Estuary and the Arthur Kill. The applications...
Structural Reliability Through Machine Learning From Case Histories
The development of a management tool for the control of structural safety is described. Artificial intelligence techniques of 'machine learning' are employed...
Multidisciplinary Hydrologic Investigations at Yucca Mountain, Nevada
Future climatic conditions and tectonic processes have the potential to cause significant changes of the hydrologic system in the southern Great Basin, where a nuclear-waste repository...
CTA's Experience in Fostering Station Redevelopment Through Public/Private Partnerships
The paper reviews the experience of the Chicago Transit Authority's partnerships with the private sector. The funding, space, design, construction and operation components...
The Magnetically Levitated Transport System TRANSRAPID?Characteristics and Aspects of Application
After a development of less than two decades the magnetic levitation TRANSRAPID is virtually ready for revenue service since 1985. The service has been continuously tested since 1985 on...
Financing Transit: Benefit Assessment in Los Angeles
The Southern California Rapid Transit District (SCRTD) has successfully used benefit assessment to fund a portion of the Los Angeles subway project and to provide the critical private...
The Extension of the Docklands Light Railway
The Docklands Light Railway is a publicly funded automated light rapid transit system that was opened in 1987, linking the fringe of the financial district of the City of London to an...
Public/Private Partnership for Development of the South Brunswick Station
Because of projections for continued residential and commercial growth and a large gap between stations, NJ TRANSIT decided to construct a new station in the Township of South Brunswick....
The Chicago-Kansas City Tollway: Lessons for Future Projects and Policy
The paper discusses an innovative mixed public-private financing plan and implementation plan for an investor-owned toll road connecting Chicago and Kansas City. The two plans utilize...
Water Resources: How Do We Slice the Pie?
New and better ways must be found to: reduce water consumption; preserve environmental values; conserve and protect existing water supplies; use surface and ground water conjunctively;...
A Method for Estimating Peak Flows from Small Agricultural Watersheds
An attempt was made to develop a method for estimating peak runoff from agricultural watersheds by analyzing precipitation and runoff data, and incorporating the results into a procedure...
Impact of Urbanization on Main Stream Flooding
The methodology, results and management implications of a stormwater study at an urban watershed experiencing increasing episodes of flooding along the main channel and flood plain are...
Finite Element Analysis of Hillslope Variations in Surface Runoff
