Partial Area, Variable Source, Rainfall Runoff Model Utilizing Digital Mapping
A partial area, variable source hydrologic rainfall/runoff model, called MAPHYD, was developed utilizing digital maps, interactive computer graphics, and several infiltration mechanisms....
Computer Aided Hydraulic Design of Open Channels
The results of tests by the U.S. Army Corps of Engineers District, Los Angeles (LAD), became a major part of the Corps' EM 1110-2-1601, Hydraulic Design of Flood Control Channels....
Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...
Density Currents and Their Application in Hydraulic Engineering: Task Committee Progress Report
The Task Committee on Density Currents and Their Applications in Hydraulic Engineering operates under the Technical Committee on Hydrologic Transport and Dispersion. The Task Committee...
A Shopper's Guide to Urban Stormwater Software, Revisited
Results of a survey of urban stormwater software were first discussed by the author in August, 1985. A trend toward widespread adoption of SCS procedures as a new standard in urban hydrology...
Identification of Automation Opportunities
Construction, although the world's largest industry, is also its most archaic. Most construction practices are very labor-intensive, with resulting impacts on safety, productivity,...
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...
Earthmoving in the Lunar Environment
This paper analyzes the lunar 'earthmoving' process with inputs, outputs, and external conditions acting upon it. Lunar environmental conditions such as temperature,...
Transportation by Pipelines in Space Colonies
The use of pipelines in space colonies to transport liquid, gas, solids and even passengers is not only feasible but also desirable. For many applications, pipelines offer a number of...
Extraterrestrials Excavation and Mining with Explosives
Explosion excavation technology may become a valuable tool for economic and efficient base station construction on extraterrestrial bodies. Criteria for explosives which can safely be...
Spacecraft Environments: Design Considerations
Design, launch, assembly in orbit, and operation of large space-based systems involve much detailed analysis to ensure mission success. The area of contamination control and environmental...
Animation/Simulation for Construction Planning
The importance of a highly efficient schedule for space construction cannot be overestimated. A detailed scheduling process working closely with design data could reduce costs, minimize...
Robotics Research for Construction in Space
Research in construction robotics, terrestrial or otherwise, has focused on issues which are broadly pertinent to space applications. Construction robotics, as addressed by this writer,...
Simulator for Telerobotic Assembly, Maintenance and Repair of Large Space Structures
A first approximation level computer simulator for telerobotic assembly of large space structures is described. Approach, methodology and initial results are presented. An example based...
Planar Space Structures
This paper describes a construction system which has a number of practical advantages for the development of space structures. It uses relatively thin materials folded into interpenetrated...
Space Station - New Venture/Old Problem
Four key operations-related costs are associated with the Space Station: (1) transportation, (2) data management, (3) sustaining engineering, and (4) integrated logistics. Life cycle cost...
The Role of a Mobile Transporter in Large Space Structures Assembly and Maintenance
Large space structures require a vehicle to support assembly, operations, and maintenance. These vehicles may be designed for specific tasks or for general use throughout the life of the...
Survey of Soviet Space Welding Technology Development
Soviet engineers clearly recognize the potential value of welding for maintenance, repair, and fabrication of structures in space. The development of this technology has followed a steady...
Comparisons Between Space Facilities and Earth-Based Analogs
This presentation will focus on the design of planetary bases and space stations as based on comparative designs for facilities in analogous harsh and isolated environments here on Earth....
Waste Management: Project Mercury to the Space Station
This paper presents my perceptions of the design of waste management systems for manned space flights. I'll follow the evolution of waste management from the early Mercury...
