Scour Protection in Bottomless Culverts
This paper will describe the relative severity of scour anticipated to occur at bottomless culverts and will provide some design guidance for scour protection based on research referenced...
A Knowledge Based System for the Design of Open Channels
The design of open channel facilities often calls for evaluation of a unique set of physical conditions which do not lend themselves to standard designs and textbook solutions. Consequently,...
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...
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...
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...
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...
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...
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...
Engineering Mechanics
This proceedings contains keynote and summary papers presented at the 11th ASCE Engineering Mechanics Conference held in Fort Lauderdale, Florida, May 20-22, 1996. The keynote papers address...
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...
Pile Wall Cuts Off Seepage (Available only in Geo/Environmental Special Issue)
An unusual cutoff wall constructed by the secant pile method succeeded in drying up seepage through the permeable strata below a saddle dam at Beaver Dam in Arkansas, owned by the U.S....
Practical Guide to Grouting of Underground Structures
This book presents a hands-on discussion of grouting fundamentals and provides a foundation for the development of practical specifications and field procedures. The author takes a practical...
Quake Proofing a Palace
A $36.5 million renovation of the California Palace of the Legion of Honor included a two-level underground expansion on a very sensitive site and the largest-ever seismic retrofit for...
Chicago's Micropile Debut
On a tight, urban site around Chicago's historic Orchestra Hall, engineers used high-capacity micropiles as an alternative to hand-dug caissons. On a $104 million project...
Uncertainty in the Geologic Environment
from Theory to Practice
The state-of-the-art is presented with respect to analytical and design methods incorporating uncertainty in the geologic environment. Particular emphasis is placed on practical applications...
Soft Ground Improvement in Lowland and Other Environments
The presence of thick deposits of soft clay combined with the effects of ground subsidence cause problems for engineering constructions for lowland areas such as the Central Plain (Chao...
