An Introduction to Pressurized Volumes in Space
Space habitation designers come from diverse backgrounds. As it is human nature to emphasize that which is familiar, habitat design is strongly influenced by the designer's...
Conceptual Design for a Lunar-Base CELSS
Future human exploration is key to the United States National Space Policy goal of maintaining a world leadership position in space. In the past, spacecraft life support systems have used...
Commercial Launch Facility Economic factors
Launch facility construction, maintenance and modification costs remain a largely invisible part of the cost of putting mass into orbit. The government can lease launch facilities to commercial...
Artificial Gravity Research Facility Options
On a long duration manned mission to Mars, the physiological changes caused by microgravity may be counteracted by artificial gravity. This paper evaluates several different classes of...
Partial Gravity: Human Impacts on Facility Design
Partial gravity affects the body differently than earth gravity and microgravity environments. The main difference from earth gravity is human locomotion; while the main difference from...
A Design Process for Water Distribution Systems Including Optimization
Design of a water distribution system is a multi-level process from preliminary planning to final detailed sizing of components. Unfortunately as in many design problems, a final detailed...
Upgrading Hydraulic Infrastructure for Level One Redundancy
In the current paper a methodology is presented for upgrading any single source water distribution system in order to provide a level one system redundancy at a minimum cost. A level one...
Soft Bottom Low Flow Channel?A New Approach
In 1987, the City of Boulder, Colorado requested assistance from the Urban Drainage and Flood Control District (District) to repair a problem of cattails growing in the low flow portion...
Key Environmental Development Issues

Restoration of a Buttress Dam
Inspections of Morris Shepard Dam on the Brazos River in Texas revealed serious defects in the dam and its foundation. Piezometric pressures below the spillway buttresses greatly exceeded...
Morris Sheppard Dam: A Rational Approach to Stability Analysis
This paper details the excessive foundation piezometric conditions found during a routine five-year inspection, and presents the results of backfigured stability analysis of a critical...
Considerations for a Multiple-Use Stormwater Detention Facility
A 60-year-old neighborhood provides the unusual setting for the City of Tulsa's Turner Park-Will Rogers High School Stormwater Detention Facility. The 20-acre site is located...
Using an Index Stream to Make Instream Flow Decisions
