Effects of Agriculture on Ground-Water Quality in Dade County, Florida
Multidepth wells at five test fields and a monitoring network of water-table wells in Dade County, Florida, were sampled twice during 1985 to determine concentrations of nitrogen, phosphorus,...

What About the Point-of-Use?
Point-of-use (POU) granular activated carbon (GAC) treatment devices are being installed more frequently on community water sytems and on private wells. This article describes carbon filter...

The Risk Factor in Water Resources
Risk is inherent in nature and society, while uncertainty depends on investigations. Decision making in water resources is most often a deterministic selection of dimensions which divide...

Hydraulic Transient Analysis on a Micro Computer
The shift toward micros has reduced prices and increased accessibility, permitting engineers to bypass 'bureaucratic' DP departments and run programs as often...

Stormwater Management in Orlando, Florida
Metropolitan Orlando, Florida contains 82 lakes and approximately 200 drainage wells which serve as ultimate outfall for stormwater runoff. The quality of the surface receiving waters...

Competitive Model Testing for Replacement Runners at the Wells Hydroelectric Project
The Wells Hydroelectric Project, located on the Columbia River, contains ten Kaplan-type turbines. The plant has been in commercial operation since January, 1969. The runners have a long...

Riverbank Stability and Monitoring at Grand Coulee Dam
The capability for hydroelectric power generation at Grand Coulee Dam was substantially increased following construction of the third powerplant in the mid 1970s. Increased river fluctuations...

Determining Soil Properties by Electric Cone Penetrometer
Gravel island construction is one primary means of establishing permanent locations for oil wells, building foundations and road beds in the arctic. The gravel provides a natural insulation...

Analysis of a Production Well Through Sediments Containing Gas Hydrates
In some of the petroleum reservoirs recently discovered north of the Arctic Circle, production wells extend through thick permafrost. Several authors have reported zones of gas hydrate...

Ice Loads on Structures With Compound Slopes
Many of the offshore drilling structures proposed for use in the Arctic have sides with multiple slopes. Sloping walls are used at the waterline to cause the ice sheet to fail in bending...

Design of an Icebreaking Offshore Supply Vessel
There are two basic scenarios for icebreaking support vessels. The first is the delivery of drilling fluids and supplies to drilling units and other development operations. The second...

Tanker Mooring/Loading Systems for Northern Offshore Arctic Regions
Transportation of crude oil in arctic areas via shuttle tankers can prove to be a viable alternative to a pipeline system. The shuttle tanker system will require offshore terminals equipped...

NPDES Permits for Accelerated Oil & Gas Development
Section 402 of the Clean Water Act (CWA) requires the Environmental Protection Agency (EPA) to develop National Pollutant Discharge Elimination System (NPDES) permits for waste discharges...

Bowhead Whales and Other Endangered Whale Species: Their Influence on Offshore Operations in Alaska
In recent years, whales have become the focus of considerable public concern, and this is manifested in the measures that are imposed to protect them from possible adverse effects of offshore...

SHADS: Mobile Arctic Drilling Platform
To minimize costs of Beaufort Sea exploration programs, the industry needed a mobile arctic drilling structure that requires little or no site preparation, does not require an active ice...

Offshore Seawater Intake in the Arctic
Waterflood has become a proven technique for enhancing oil recovery from oil producing reservoirs. At Arctic north slope areas, seawater has been used successfully for such operations....

Coastal Erosion's Impact on California Offshore Oil Development
Recent oil discoveries in the offshore Santa Maria Basin and the Santa Barbara Channel will require the construction of new oil facilities located along 90 miles of Santa Barbara County...

Coping with Transition: Improving the Management Process
At Arkansas Power & Light Company, the Energy Supply Department has some 2,000 employees and operates (in addition to providing General Office engineering, technical, and administrative...

Fracture Mechanics Analysis of Massive Hydraulic Fracturing Containment
The hydraulic fracturing containment problem is the subject of the present investigation. Unlike previous studies, the interface crack geometry with the correct crack tip singularity was...

The National Water Well Association's Ground Water Software Centre
The National Water Well Association (NWWA) offers a new service to the members of the ground water industry. NWWA's Ground Water Software Centre markets computer programs...
