Exploring Karst Terrain with Air Track Drilling
Pneumatic-powered track-mounted, percussion drills can be used to perform or augment geotechnical investigations in some karst settings. The air track drill is best suited to exploring...
Geotechnical Exploration and Site Preparation Techniques for Large Mall in Karst Terrain
A large commercial mall and secondary developments were planned for construction in a karst area near Clarksville, Tennessee. A geotechnical exploration was conducted to evaluate the occurence...
Terrain Modelling for Computer-Aided Site Development
This research proposes a terrain model and a storm drainage model to be used as tools in creating a more efficient design/approval stage of the development process. This research proposes...
Geotechnical Aspects of Karst Terrains
Exploration, Foundation Design and Performance, and Remedial Measures
The presence of solution cavities in karst terrains poses some unique problems in site exploration, design of foundations, and in remediation of problems with existing structures. Case...

Geographic and Spatial Data Management and Modeling
A geographic information system is a computer based technology for storing and using spatial data. Many alternative methodologies exist for managing the three general types of spatial...
Accumulation of Streamflow in Complex Topography
A proposed synthetic watershed model which simulates the hydrologic process of both overland flow and interflow is presented in this paper. The synthetic model has features designed to...
Can Digital Terrain Data Cut Route Selection Time?
The use of photogrammetry in the collection of digital terrain and the use of a computer to process data is not being used to its fullest. Use of these two tools together increases access...
Computing in Civil Engineering
A broad spectrum of computer applications in civil engineering is covered in 73 papers presented at the Third Conference on Computing in Civil Engineering. Emphasis is on microcompters...
The Potential for Small-Scale Hydro in Developing Countries
The author attempts to define a market that has been traditionally ignored by U.S. design firms. As a result, the Europeans, Chinese and Japanese have taken the lead in engineering and...
Vail Pass Highway�Respecter of Mountain Ecology
Environmental constraints to a large degree controlled both the design and construction of a 14-mi segment of Interstate Highway 70 through Vail Pass in Colorado and necessitated adoption...
Terrain Analysis for the Trans-Alaska Pipeline
Airphoto interpretation and field reconnaissance were combined with a computer-based data bank to evaluate the diverse terrain conditions along the Trans-Alaska Pipeline because acquisition...
Off-Highway Transportation in the Arctic
Because of the terrain and lack of roads in the region, a new breed of off-highway vehicles has seen heavy service in the Arctic and north slope of Alaska. These vehicles include rubber-bag...
Austin's 11-Mile Sewer Tunnel Reflects Sound Economic, Environmental Alternatives
An 11-mile long $20,000,000 concrete-lined continuous tunnel has just been completed across the City of Austin to serve as a sanitary sewer. Most of the tunnel is more than 100-ft (30.5-m)...
