Mitigation of Dust Contamination During EVA Operations on the Moon and Mars
The Space Exploration initiative is charting a new course for human exploration of the Moon and Mars. Advances in EVA system have been identified as being critical for enabling long-duration...
Medical Care on the Moon
Eventually, people will return to the Moon to stay for prolonged periods of time. When they do, they will be exposed to a wide range of threats to their health including, decompression...
Regenerative Life Support Technology Challenges for the Space Exploration Initiative
Regenerative life support systems have been identified as one of the critical enabling technologies for future human exploration of space. This discipline encompasses processes and subsystems...
Mitigation of Adverse Environmental Effects on Lunar-Based Astronomical Instruments
The galactic cosmic-ray flux incident on the Moon was examined for its potential adverse impact on the performance of the large lunar telescope (LLT) proposed as a part of NASA's Space...
A Systems Approach to Water Recycling Research
Because of the cost of Earth resupply, water recycling from wastewater is a critical enabling technology for long duration space missions. The need and the fact that water quality is not...
Effective Airport Environs Planning in the 1990s
A properly coordinated environs planning effort provides a guide for development and redevelopment of the land and facilities surrounding the airport. Airport environs planning, coupled...
Minneapolis/St. Paul International (MSP) Part 150 Implementation Design Overview
In February 1991, Matropolitan Airports Commission (MAC) selected the consulting team of Aviation Planning Inc., Wyle LAboratories Inc. and the Center for Energy and the Urban Environment...
Aircraft Noise Monitoring at Denver International Airport
This paper describes design of the noise monitoring system for Denver International Airport. When the airport opens in 1993, the system must monitor compliance with two standards established...
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....
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...
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...
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...
The Transport and Fate of Drilling Muds
The disposal of drilling muds from offshore oil platforms is of concern because of the potential effects of pollution from these muds. Both drilling muds and fine-grained bottom sediments...
Estuarine Environmental Impact Assessment Using a Three-Dimensional Circulation and Transport Model
Two case studies of estuarine environmental impact assessment using a recently developed three-dimensional circulation and transport model are presented following a brief overview of the...
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...
