This paper discusses Chapter 5, Reservoir Sedimentation, of the U.S. Army Corps of Engineers' Engineering Manual (EM) on Sedimentation Engineering, EM 1110-2-4000. The chapter...
Analysis of Spillway Failures by Uplift Pressure
Results of a model study to evaluate the development of uplift pressures beneath concrete chutes are presented. Two spillway failures are described to support the study results. Common...
Hydroturbine Efficiency and Cavitation Monitoring
The paper describes a microcomputer-based system for monitoring hydroturbine performance and cavitation level. Remote access to the monitoring system provides convenient, rapid, and accurate...
Uncertainty and Value Analysis in the Selection of Dam Modification Alternative
Objectives and attributes were decided by the dam and watershed requirements, value judgments of decision makers, quantified trade-offs between different attribute values, and technical...
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...
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...
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...
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,...
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
