A Multi-Dimensional Transport Model Utilizing a Characteristic-Galerkin Approach
A multi-dimensional transport model based on the RMA series of finite element models has been developed utilizing a characteristic-Galerkin approach. This paper examines the application...
Numerical Modeling of Advective and Diffusive Transport in the Rappahannock Estuary, Virginia
A laterally integrated, two-dimensional real-time model, consisting of linked hydrodynamic and water quality models, was developed to study hypoxia in the tidal Rappahannock River, a western...
Environmental Modeling of Coastal Wetlands
Several useful modeling techniques have been developed for the numerical solution of the vertically integrated Reynolds equations on unstructured grids in wetland environments. The objectives...
Issues Related to Modeling the Transport of Suspended Sediments in Northern San Francisco Bay, California
Measurements of suspended sediment concentrations at several deep-channel stations in San Francisco Bay are reviewed. Sediment concentrations are found to be strongly correlated with delta...
Directional Wave Data ? Measurements and Modeling Coast of Florida Erosion and Storm Effects Study
The U.S. Army of Corps of Engineers, Jacksonville District, and the Florida Department of Enviromental Protection are co-sponsors of a study to evaluate the coastal processes along the...
An Experimental and Analytical Study of the Shoreline Response to Non-Parallel Breakwaters in Oblique Waves
REsults of an experimental and analysis study single breakwaters on oblique waves are presented. Three orientations of the breakwaters are studied, those being parallel to the shoreline,...
Modeling Bottom Friction in Wind-Wave Models
Effects of bottom friction in wind-wave models are investigated, with an emphasis on wave-induced bottom roughnesses (moveable-bed effects). A state-of-the-art bottom friction model is...
Airport Terminal Design Challenges
In February 1989, the Metropolitan Washington Airports Authority began the process of designing and constructing a new terminal at Washington National Airport to address the needs of its...
Rail Service to Airports
Rail service is available at seven North American airports, and service is available by a shuttle bus connection at more than nine other North American airports. Additionally, rail service...
Rail-Air: A Multi-Modal Opportunity in a Changing World
The purpose of this Paper is to examine the applicability of rail links to major airports and the benefits they can bring. It will seek to identify the key success factors and the extent...
Switzerland: Rail Access to Airports and the Fly-Luggage System
Swissair and the Swiss Federal Railways (SBB) offer a unique service for air passengers travelling to and from their Swiss airport of departure or arrival. In conjunction with private...
Cost Considerations in Planning Pier Terminals
The deregulation of the air transport economy is gradually leading to the involvement of private developers in airport terminal financing. Even the airports run by government agencies...
Airports and Air Quality Issues - the European Perspective
This paper presents a detailed review of air quality studies at European Airports since 1986. It also provides a brief analysis of the air quality section of a recent ACI (Europe) environmental...
Prediction of Gravel Bedload with SAM
Bedload measurements for Little Beaver Creek in Colorado were used to test the sediment transport functions included in SAM. The test results showed that Toffaleti predicts total bedload...
Procedures for Evaluating the Effects of Sedimentation on Flood Hazards in Urbanized Areas in the Southwestern U.S.
Urbanization of watersheds in the arid Southwestern U.S. creates problems for resource agencies and design engineers. Traditional analytical techniques that are generally applicable to...
Development of Missouri River Navigation Analysis
The navigation analysis for the Master Manual review examined mainstem reservoir regulation alternatives by evaluating the benefits of reservoir releases for barge transportation. Navigation...
Public Involvement and Participation: Planning Imperatives for the Coming Century
The literature has identified three types of responses to natural resources planning and management efforts in the United States. The first focused upon the more effective use of existing...
The Channel Tunnel: Larger Than Life, and Late
The Channel tunnel opens in May, but passenger service will be delayed while final testing on trains and electrical systems are completed. The English Channel tunnel crossing is the world's...
Intelligent Tutoring Systems to Aid Water Treatment Plant Operators
Training for water treatment plant operators exists primarily through short courses at colleges or technical schools, self-study manuals, and on-the-job training. Intelligent tutoring...
Development of an Expert System to Identify Hazardous Highway Spots
