Frontal Dynamics and Circulation of the Upper Layer of a Fjordsystem with Complicated Topography
The impact of controlled (varying) discharge from a hydroelectric power plant on the upper layer circulation and hydrography of a fjord system is studied. The system is a fjord with two...
Modeling the Pathways of Nonconservative Substances in Estuaries
ELAmet is a model for nonconservative chemical transport which solves the advection/dispersion/transformation equation using a modification of Eulerian-Lagrangian methods. In this paper...
Modeling Transport and Fate of Micropollutants in Coastal Waters
In order to assess rate and risk of pollution of coastal waters, attention should be given to the input of pollutants, the transport of pollutants, the transfer of pollution between water...
Circulation Modelling and Water Quality Prediction
A circulation and water quality modelling system for use in areas where horizontal transport is dominating is presented. The water quality can either be described as BOD-DO processes or...
The Importance of Density Driven Circulation in Well Mixed Estuaries: The Tampa Bay Experience
This paper addresses the importance of the effects of baroclinicity in subtidal dynamics of a well mixed estuary, Tampa Bay. The analysis is based upon numerical simulations using a three-dimensional,...
Modeling Tidal and Wind Driven Circulation in Sarasota and Tampa Bay
As part of an effort to quantify the effects of hydrodynamics on water quality within Sarasota Bay, Tampa Bay and their adjoining waters, a field and modeling study of circulation and...
Control of Contaminant Transport in Estuaries
This paper describes the development of a computational procedure for the adaptive control of hazardous releases in a vertically-mixed estuary. In particular, the control strategy is aimed...
Application of a Boundary Fitted Coordinate Mass Transport Model
A three-dimensional, boundary fitted coordinate, finite difference, mass transport model was applied to the Providence River in Upper Narragansett Bay, Rhode Island. The governing advection-diffusion...
Water Quality Modelling: Prediction of the Transport of Water Constituents in the Weser Estuary (Germany)
Water quality monitoring of the Weser estuary is carried out in conjunction with numerical modelling of the transport processes. For analytical and prognostical studies, and especially...
A Three-Dimensional Simulation of Buoyancy and Wind-Induced Circulation and Mixing in the New York Bight
A three-dimensional simulation of the circulation and mixing in the New York Bight has been conducted, forced by (i) wind stress for the year 1987 and monthly-mean heat fluxes at the sea...
Assessing
The New York Bight had been receiving waste disposals, dredged spoils and acid dumps for the past 30-40 years causing accumulation of trace metals such as Cu(II) in water and sediment....
A PC-Based Integrated Water Quality Impact and Analysis System
An integrated water quality model system (WQ Shell) has been developed for the PC. The system is designed to provide an easy-to-use graphical interface which integrates geographical and...
Sensitivity of Flow and Salt Transport to Uncertainties at Open Boundaries: A 3-D Experience
Understanding the transport due to tidal and sub-tidal exchange processes enables many environmental issues in estuarine systems to be addressed. To achieve this goal, a reliable numerical...
Pollutant Transport Modelling in Large River Plumes
The Niagara River plume in Lake Ontario and the Fraser River plume in the Strait of Georgia are of similar spatial dimensions, and arise from rivers with comparable discharge. Both rivers...
Approximation of Convective Processes by Cyclic AOI Methods
Convective or advective processes play a role in many models for civil engineering applications. For example in transport equations, in hydrodynamic equations or wave energy equations....
The Last Freeway
Ever since what's now known as the Pasadena Freeway was completed in 1940, Los Angeles has been synonymous with the freeway�first with the ease and speed of transport it represented...
A European Road Comes to the U.S.
From Sept. 7 to Sept. 22, a group of 21 federal and state transportation officials and industry representatives participated in the European Asphalt Study Tour, traveling the roads of...
Lunar-Based System to Supply Power to Earth: Summary of Concept, Benefits, and Development
The Lunar Power System (LPS) is described, references are given to other published work, and possibilities for demonstrating LPS are outlined. Analyses indicate that LPS can provide inexpensive...
Computer Modeling of Structural Systems for Residential Scale Buildings
The majority of housing in the United States is single family residences or low-rise multiple family dwelling units. The structural systems usually consist of rather uncomplicated types...
Opportunities for Improved Transportation Planning
The approaches, technical procedures, and analytical methodologies utilized for urban transportation planning need to be improved if the intent of the 1990 amendments to the Clean Air...
