The capabilities of empirical modeling techniques are discussed and three promising mechanistic models to simulate sediment-water interactions are reviewed with respect to their possible...
Evolution of Appropriate Technology
Although appropriate technology has been practiced since the beginning of people on earth, the inventiveness of the 20th century is forcing engineers (and others) to look at the multitude...
Environmental Considerations in Sustainable Development and the Application of Appropriate Technology
A fundamental appropriate technology concept is that technologies, as well as the development process, must be environmentally sound. As stated by the United Nations' World...
Using Social Infrastructure in Support of Appropriate Technology
This paper proposes and argues for an expanded definition of social infrastructure, suggesting that the creation, adoption and maintenance of appropriate technology are dependent upon...
Education, Research and Training for Appropriate Technology
Much has been written about appropriate technology (AT) and how to accomplish it. This paper adds to that literature with specific ideas for education, training and research programs and...
Application of a Generalized Risk Dynamic Model to a Spillway Design Flood
Risk analysis can provide a logical basis for selecting the optimal design capacity of a flow conveyance hydraulic structure for the least total cost or specified non-exceeding risk levels....

Enhancing Effluent Water Quality of Sedimentation Basins Using Constructed Wetlands Technology
The Tennessee Valley Authority (TVA) has constructed twelve wetlands to treat acid drainage at reclaimed coal mines and fossil-fueled power plants. These wetlands are designed primarily...
Safety Analysis of Handset Wood Slab Formworks
A reliability index is calculated for flexural strength of a handset wood slab formwork system. Load and resistance models are based on a survey of construction loads and wood test data...
Limit States Design of Wooden Formwork for Concrete Walls
Load and resistance factors are developed for ultimate limit states design of wooden formwork components for concrete walls when the lateral concrete pressures are computed using the ACI...
Development of Standards for Slipform & Jumpform Works
Review of past work indicates substantial effort has been made to publish construction standards and guidelines for slipforms but published material pertaining to jumpforms is scarce....
A Design for Automated Pavement Crack Sealing
An automated crack sealing system can have substantial economic benefits including reduced labor costs, improved quality, and improved safety. While automating crack sealing is technically...
Construction and Robotics: Problems and Solutions
The role of robotics in construction, and the role played by construction engineers (CE's) is placed in perspective. Robot development, like machine manufacture, has always...
Automation of a Truck-Mounted Drill Rig
Truck-mounted drill rigs used for soils properties investigation, foundation evaluation, ore exploration, and producing monitor and water wells typically require, because of their weight,...
The CRANIUM: A Case Study of Sensory Improvement for Construction Equipment Operators
Machines excel at physical processes such as generating large forces and performing repetitive motions, but humans are still better at information intensive processes such as planning,...
Project Management in Areas of Socio-Political Conflict
Project managers routinely deal with project locations which provide adverse environmental conditions. A location in which social and political conflict exists may prove to be extremely...
Restructuring Responsibility and Reward for More Construction Innovation
This paper proposes modifications to the contractual systems customary in the U.S. construction industry with the objective of encouraging technology innovation. The relationships among...
