Laboratory Evaluation of a Conductivity Probe for Scour Monitoring
Laboratory tests were used to evaluate the ability of conductivity sensors to measure streambed elevation. Tests were completed on a 2.1-m probe with a resolution of about 8 cm that was...
Evaluation of Selected Instruments for Monitoring Scour at Bridges in New York
Reliable methods to monitor scour at bridges are needed to ensure public safety and minimize the cost to repair or replace vulnerable bridges. The U.S. Geological Survey, in cooperation...
Bank Protection Toe-Downs and Local Pier Scour
The zone-of-influence for pier scour may impact bank protection toe-down depths. Countermeasures were required at a site along the Salt River in Phoenix, Arizona when the alignment of...
Effect of Reservoir Hedging on Crop Yield Under Deficit Irrigation Conditions
In case of irrigation projects, irrigation scheduling at the field has a direct bearing on yield crops. Hence, the various reservoir operating policies considered have to be evaluated...
Sedimentation Dynamics of Tidal Inlets
Tidal inlets are very dynamic systems subject to continuous morphological changes under the action of tides, waves and transported sediments. Although flow and sediment dynamics are interactive,...
Brownfields Boom
A brownfield is a leftover, unused industrial land parcel thought to have a prohibitively expensive clean-up required before developing. For years brownfields were battlefields for litigation...
Cleaning Up Clay
Using soil vapor extraction to remove volatile organic compounds from ground water and unsaturated soils can achieve faster and more-complete cleanups than conventional pump-and-treat...
Creeping Suspicion
High-capacity, epoxy-coated anchors were installed at Upper Occoquan Dam to increase the stability of the 70-foot-high concrete gravity dam and powerhouse under revised Probable Maximum...
Anchoring a Landfill Expansion
Design of a grading plan for a landfill expansion in Los Angeles County was complicated by slopes with adverse bedding planes, permitting stipulations and property setbacks. Flattening...

A Post-Earthquake Reconnaissance of Port Facilities
Prepared by the Committee on Ports and Harbors Lifelines of the Technical Council on Lifeline Earthquake Engineering of ASCE.
Monitor Well Design, Installation, and Documentation at Hazardous and/or Toxic Waste Sites
This manual provides the minimum elements for consideration in the design, installation, and documentation of monitor well placement at projects known or suspected to contain chemically...
Shake, Rattle and Map
Researchers at Stanford's Earthquake Engineering Institute are developing an innovative system that uses geographic information systems to predict earthquake damage. A case study shows...
Riddle of the Riverbed
The design of the Salt River Viaduct as part of the Red Mountain Freeway in Phoenix, Arizona, presented unique geotechnical problems. A cemented silty clay layer underneath the surface...
Boston's Home Run
The $1.3 billion Ted Williams Tunnel, the first part of Boston's Central Artery/Third Harbor Tunnel Project to be completed, has been designated the Outstanding Civil Engineering...
Scour Power
New prediction methods consistently calculate scour around bridge piers allowing engineers to better tailor pier design in rock and consolidated material. The leading cause of bridge failure...
Defect Detection (Available only in Geo/Environmental Special Issue)
Sonic integrity logging technology can detect flaws in deep foundations more reliably and at less cost than conventional boring techniques. These non-destructive test tools are being used...
