Distributed Hydrologic Modeling of Humid Regions
Distributed physically-based hydrologic modeling of humid watersheds with shallow soils is complicated by non-Hortonian runoff production mechanisms. This paper presents a numerical experimental...
A Practical Approach to Watershed Sanitary Surveys
A step-by-step approach for conducting watershed sanitary surveys can be successfully applied to watersheds of all sizes. The approach involves preparing a watershed map, contacting regulatory...
Fish Passage Pool Bedding Analysis
Anadromous fish passages, stream dynamics and the artifical channel segmented into a natural stream should fttnction seamlessly. This paper intends to develop reasonable procedures a designer...
On Silt Abrasion Erosion of Three Gorges Hydraulic Turbine in the Future
In this paper the basic parameters of Three Gorges hydraulic turbine have been reviewed and the operation characteristics of Three Gorges hydropower Station pointed out. Combined with...
Irrigation of Grain Sorghum on the Delmarva Peninsula
Irrigated grain sorghum experiments were conducted for two years on a Norfolk sandy loam soil. Full irrigation was compared to partial irrigation and no irrigation in a randomized block...
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...
Real-Time Construction Staking
Surveying has changed from a profession in which one learned skills on the job and could even become licensed without a degree. Now firms are turning to high tech equipment using geographic...
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...
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...
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...
