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...
Design Modification of Water Supply Intakes in Mountainous Regions
Existing river intakes for several water treatment plants in the mountainous areas of western Venezuela have experienced severe difficulties with deposition of sediment. Excessive sediment...
Strategies for Operation of Orange County Water District Talbert Seawater Intrusion Barrier, California
Heavy groundwater production in the area of coastal Orange County accounts for large seasonal fluctuations in water levels that can cause groundwater gradients to reverse seasonally. The...
Transport Modeling of the Coastal Waters of Oahu, Hawaii
A hydrodynamic model of the coastal waters around the island of Oahu, Hawaii has been constructed to provide quantitative information on the movements and mixing of water that are to be...
The Fate of Pathogenic Organisms in Mamala Bay
The fate of enteric organisms in Mamala Bay is studied using coupled hydrodynamic and pathogen fate models. The purpose of the study is to determine the contributions of various sources...
Integrated Facility Information Systems: Total Information Access
This paper will attempt to fill the void in computer information handling with regards to facility management information by providing those in the water industry with tips and suggestions...
Privatization and Water Supply/Treatment Projects
Privatization is often mentioned as a way to get much needed, but difficult to finance infrastructure projects delivered for both developed and developing countries. However, the suitability...
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...
From Sediment to Solid
While closing a 32 acre, storm-water impoundment area contaminated with petroleum waste sediments at an oil refinery, engineers came up with a more-effective treatment plan that saved...
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...
Visualizing the Flow
Digital modeling of passive cooling techniques now enables engineers to create comfortable environments in even the most unlikely of spaces�including glass atriums in the desert. Passive...
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...
