Rocket Fuel to Earth Orbits from Near-Earth Asteroids and Comets
The analysis describes an architecture to bring 10,000 tons units of rocket fuel ore, propellant and construction mass back to low Earth orbit from newly discovered near-Earth comets or...
In Situ Recovery of Water from Dormant Comet Cores & CI Carbonaceous Chondrites
Water and volatiles may be produced by drill holes into dormant comet cores or class CI or CM asteroids. This is modeled after in-situ mining as in the Frasch process sulfur mines of the...
Uniform Traffic Impact Assessment Studies?A Case History of Riverside County, California
A publication was issued by the Transportation Department of Riverside County, California, in December of 1989 which required all traffic impact studies performed for new development to...
Urban Transportation Management?Jersey City, New Jersey

Lagrangian Transport Simulation Using Video Images to Store and Retrieve Parameters
A new technique based on Video Images for Storing and Retrieving parameters (VISR) and its application to model pollutant transport using the Lagrangian discrete parcel method is presented....
3-D Particle Tracking for the New York Bight
This paper describes the development and testing of a three-dimensional particle tracking model for the New York Bight. A number of particle tracking options have been developed to predict...
An Experimental Model Using a Graphical User Interface
This paper describes a program named Plume which runs on a microcomputer. The intended function of the program is to enhance an investigator's understanding of the estuarine environment...
Techniques for Visualization of Estuarine and Coastal Flow Fields
A variety of formats for the display of velocity vector components are presented and assessed. The effective transmittal of information to the viewer is the criterion emphasized. The special...
Developments of Modelling Software for Civil Engineers
The paper describes some of the recent problems in the development of software tools for civil engineers, especially software for hydrodynamic and water quality simulations for environmental...
Methodology for Validation of a Tampa Bay Circulation Model
The National Ocean Service is presently conducting the Tampa Bay Oceanography Project, including development and application of a three-dimensional circulation model to the Bay, and collection...
Field Verification of a Wave-Induced Current Model
A unique data set of nearshore waves and current measurements over a bar-trough bathymetry was collected during a field experiment at Duck, NC, in October 1990. These high-quality data...
Modeling Three-Dimensional Circulation and Sediment Transport in Lakes and Estuaries
The transport of fine sediments due to currents and wind waves in estuaries and lakes have been studied by means of field experiments, laboratory experiments, and a comprehensive three-dimensional...
Thirty Year Simulation of Chesapeake Bay Eutrophication
Eutrophication processes in Chesapeake Bay, 1959-1988, are simulated using a three-dimensional model package. Results link the volume of anoxic water to degree of stratification and to...
Passive Dispersive Transport Modelling: Comparison with Experimental Rhodamine Data in the Elbe Estuary, Germany
Aiming at modelling of the complex water mass, suspended matter and pollutant transport in a tidal estuary, the ability of simulating the transport of passive, conservative tracers is...
Nowcast Protocol for the Great Lakes Forecasting System
The Great Lakes Forecasting System is a cooperative federal-university undertaking designed to implement a predictive system for each of the Great Lakes. The desired forecasts concentrate...
Model Development for Operational Use to Help Spill Combating and Sea Rescue
Based on twenty years' experience on flow velocity measurements, transport experiments and numerical modeling the three-dimensional (3D) models of water currents, transport and water quality...
A Shell Approach to Modeling Oil Spill Trajectory and Fate and Search and Rescue Operations
A shell approach is employed to facilitate the application of an oil spill trajectory and fate and search and rescue model to a wide variety of geographic areas. In this strategy the model...
A Coastal-Ocean Hindcast/Forecast Model
Flows in the coastal oceans are produced by interactions of different components: tides, winds, buoyancy discharge from estuaries, topography and remote forcing of deeper-ocean origin....
A PC Modelling System for the Simulation of Transport and Fate of Solutes and Suspended Substances
