Lysimeters for Evapotranspiration and Environmental Measurements
Lysimeters have been used extensively in the past to provide baseline information for development, calibration, and validation of evapotranspiration methods. This proceedings,
Ground-Water Modeling Without Fear
Computerized ground-water modeling has leapt from the cloistered laboratory to the field project as more and more programs are written for the personal computer. These easy-to-understand...
The Soil-Rock Boundary: What is it and Where is it?
A major issue in many areas of Civil Engineering practice is the boundary between earth materials that are defined as soil and those that are defined as rock. Designers, contractors, and...
Problems with Rock Excavation Specification in Alberta
As a result of contract overruns and claims from classification, measurement, and payment for 'solid rock' excavation, Alberta Transportation and Utilities embarked...
Where Does Rock Begin Beneath Philadelphia?
Philadelphia provides an excellent example of the engineering problems associated with the interpretation of saprolite/weathered rock/sound rock profiles. The bedrock beneath the city...
Special Bedrock Conditions in Greater Boston
The Cambridge Argillite, a weakly metamorphosed shale, forms the major portion of the Boston Basin, a structural as well as topographic depression. In the greater Boston area, the argillite...
Where Does Rock Begin for Three Highway Projects?
'Where does rock begin?' was a question raised on three large highway projects in the western United States. The question was successfully answered by a variety...
Ground Stabilization in Shallow Depth Soft Ground Tunneling
A new approach was employed for ground stabilization to drive a semi-circular cross-section tunnel with overall dimensions of 24 ft (7.3m) wide, 12 ft (3.7m) high, and 164 ft (50.0m) long....
Conflict in Water Management of James River, ND
Delivery of water from storage in Jamestown Reservoir to 898 acres of newly developed irrigation along the lower James River by the U.S. Bureau of Reclamation during the drought of 1988...
Recent Advances in Cone Penetrometer Measurements (Software and Hardware) and Its Application to Liquefaction Susceptibility
Some of the recent advances made in Cone Penetration Test (CPT) data acquisition system and real time processing of CPT data are presented. A key component of the new CPT data acquisition...
Out of the Lab...and into the Field?
Materials experts know very little about concrete's basic structure. Now, though, engineers at a research center sponsored by the National Science Foundation are working on...
Inelastic Behaviors of Pipelines Buried Through Liquefiable Zone
For the case of a major pipeline transmission system buried through in soil deposits that may be susceptible to liquefaction, its seismio environments can be considered in the following...
Gas System Repair Patterns in San Francisco Resulting from the 1989 Loma Prieta Earthquake
Leak repair calls in San Francisco were tracked immediately following the 1989 Loma Prieta earthquake. This information was subsequently obtained from PG&E and examined for possible...
Using Real-Time Location Information for Hazardous Materials Shipments
Real-time location information on shipments of hazardous materials can be used to update routing decisions while the shipments are in transit. The effects of unforeseen delays, accidents...
Guideline for Structural Condition Assessment of Existing Buildings
Changing economic conditions, concerns for historic preservation, emphasis on fully utilizing conveniently located structures, space shortages, and increasing cost of materials and products...
Geotechnology: An Environment of Change
Today's contaminated materials�soil and water�have been investigated and analyzed by geotechnical engineers for a long time. No other branch of engineering is better positioned,...
Reliability-Based Design of Tunnel Support in Jointed Rock
The presence of joints in a rock mass may cause local instability of the tunnel support and its effect on safety should be included in design. Because of significant uncertainties in the...
Autocorrelation Functions for Offshore Geotechnical Data
Autocorrelation functions are described. Data from several North Sea sites are analyzed with respect to the vertical and horizontal autocorrelation of a number of soil properties. Based...
Analysis of Earthquake Response at a Site With Uncertain Properties
The problem of earthquake response of a soil deposit with uncertain properties is studied in the paper. Various analysis procedures for handling the dynamic response of an uncertain system...
