Not Your Father's Strain Gauge
A new type of strain gauge incorporates smart memory methods to assess changes in structures. Inexpensive, easy to install and durable, these gauges are passive peak strain sensors, which...
Inspecting the Unknown (Available in Geo-Environmental Special Issue Only)
Unknown foundations have plagued civil engineers for years. In the case of underwater pilings, much time and money is spent inspecting for cracks, breaks or deterioration. Even then, visibility...
Deep Mixing Method: A Global Perspective
Various contemporary deep mixing method (DMM) techniques have been used in the United States since 1986. Such techniques owe their origins to Japanese and Scandinavian developments, which...
Monumental Restorations
Modern nondestructive field surveys and state-of-the-art static dynamic monitoring systems provide important information for historical renovations while ensuring that the structure remains...
Automated Monitoring at Tolt Dam
As dams age, maintenance needs and safety concerns increase. Dam safety officials are placing greater emphasis on automated instrumentation, monitoring and reporting systems. A look at...
Mapping with a Differential
A southern New Jersey landfill is using Differential Global Positioning System topographic surveying to cut costs and turnaround time on annual mapping and volume certification. Modern...
Optimal Fiber Optics
Fiber optics, which played a crucial role in reinventing the telecommunications industry, have historically been noted for their potential in other facets of science and technology. Yet,...
Fathoming the Strength of Structures
More and more, the owners of bridges and piers are budgeting rehabilitations based on inspections done underneath the waterline. Increasingly, they want the underwater inspectors to be...
Intelligent Civil Engineering Materials and Structures
This report surveys the interdisciplinary research activities focused on the applying new technologies to infrastructure systems. Traditional civil engineering tools are not sufficient...
Grouting Pains (Available in Geoenvironmental Engineering Special Issue)
The article focuses on a new grouting technique for filling holes drilled during site investigation. The holes are grouted as the drill is withdrawn from the hole, instead of filled later....

Dormant Season Alfalfa Water Balance on the NIIP
Non-growing season water balance parameters were measured for alfalfa under high-elevation desert conditions of the Navajo Indian Irrigation Project in northwest New Mexico. The lysimeters...
Instrumentation for Field Measurement of Abutment Scour
Prototype scour monitoring instruments were installed on a sloping abutment as part of a research project to develop scour instrumentation. Abutment installations create new and sometimes...
Potential-Scour Assessments at 130 Bridges in Iowa
A total of 130 highway bridges in Iowa were assessed for potential scour using a potential-scour index developed by the U.S. Geological Survey for a bridge-scour study in western Tennessee....
Delineating Subsurface Contamination Using Geostatistical and Non-Intrusive Geophysical Methodologies
Electromagnetic (EM) conductivity surveys are becoming a more practiced technique in screening for contamination of soil and groundwater. This non-intrusive geophysical approach detects...
