Development and Application of the Chesapeake Bay Eutrophication Model
The paper discusses the formulation of a steady-state coupled hydrodynamic/water quality model of Chesapeake Bay. The intent of this model was to provide insight into the processes and...
Sediment Variability Mark Twain Lake, Missouri
This paper looks at the historical variability in suspended sediment loads in the Upper Salt River Basin above Mark Twain Lake, Missouri in an attempt to assess the magnitude of suspended...
Physical Model of Local Scour at Grade Control Structures
A physical model of local scour occurring at grade-control structures was operated at an undistorted Froude number prototype-model scale ratio of 1:4. The maximum unit discharge in the...
Stormwater Management by Utility Approach
Traditional methods of financing municipal stormwater operations and improvements through general city fund revenues has passed. A utility approach providing a continuous, uniform flow...
Constraints on Lunar Base Construction
This article discusses the development of scenarios and designs for the construction of a lunar base or network of bases, which will require close attention to the natural and human constraints...
Intelligent Construction Machines for Initial Planetary Shelter Fabrication
There have been any number of artists panoramas of initial base and habitat construction on other planetary bodies, notably recently the moon. Most of these conceptual drawings assume...
Space Artificial Gravity Facilities: An Approach to Their Construction
In the course of adaptation to a space microgravity environment, humans experience cardiovascular deconditioning, loss of muscle mass, and loss of bone minerals. One possible solution...
Adaptable Crew Facilities for Future Space Modules
This paper discusses life-size studies recently carried out on advanced crew accommodation features for future space module utilization. The studies are based on exploratory designs for...
Evaluation of Methods for Recovering Crew Members and Equipment Adrift from the Space Station
Among the most frequent industrial accidents are those involving falling workers or dropped equipment. There is no reason to believe that such accidents will not occur in space. (In fact,...
Solar Power Satellite - A Re-Visit
The United States should renew activities investigating the production of baseload electrical power for use on Earth from space. Technology change, world events, and the dictates of the...
Solar Water Heater for NASA's Space Station
This paper describes an investigation of the feasibility of using a solar water heater for NASA's Space Station. During the investigation computer codes were developed to...
Indirect Solar Loading of Waste Heat Radiators
Waste heat from space based power systems must ultimately be radiated away into space. The local topology around the radiators must be considered from two standpoints: the scattering of...
The Human Element in Space: Lessons from Antarctica
The human ability to adapt and perform in an extreme environment during periods of prolonged isolation is influenced by a number of social, cultural, and psychological parameters. These...
Non-Ionizing Radiation Exposure in Space Activities
Non-ionizing radiation exposure has received considerable attention over the past few years due to the potential health hazards involved. Different limits have been set with no international...
Space Operations - Care and Handling of Remains
On earth, effective methods have accommodated all functional and operational facilities and entities necessary for the handling of human remains. None have been overlooked or omitted....
Interdisciplinary Course in Engineering Education
Few would disagree that an undergraduate education should equip the engineer with more than technical competence. The subject of this paper includes discussion of a senior-level interdisciplinary...
Nature's Solutions to Space Insulation
Humans working or living in the harsh environment in space must be protected from temperature extremes. Any effective insulating system must be able to withstand a wide range of temperatures....
Surgery in the Microgravity Environment
As man becomes more active in space, the possibility of major medical emergencies requiring surgical procedures will increase. Surgery in the microgravity environment involves many challenges...
Objectives of a Space Station
A space station provides the next step in expanding human frontiers. The space station will produce certain short-term benefits as well as create a space infrastructure. Manned exploration...
Solutions to Space Station Designs
Any space station that is to be designed for extended human use may require gravity. The artificial gravity field required can be produced by rotating the structure. As the Soviets have...
