An Experimental Study on the Effect of Wastewater Application in Dry Wells and Its Impact on Groundwater
A study was conducted in order to gather accurate information on the effectiveness of dry wells for use in wastewater disposal and the effect of such disposal practice on groundwater....
Gas Transfer and Secondary Currents in Open Channels
Laboratory flume experiments on water-wide controlled gas transfer, such as reaeration, are described. The experiments indicate that gas transfer is a surface renewal process, well described...
Modification of the Step Drawdown Test for Pump Selection
This paper suggests a slightly modified mathematical model for pump tests whose aim is to design the correct pump for a well. The advantage of the model presented is that it incorporates...
Monitoring Groundwater Quality in the Southwest
Monitoring groundwater quality near sources of pollution in the southwest commonly involves highly productive alluvial aquifers. Experience in monitoring in such a setting indicates that...
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...
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...
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...
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...
Single Point Mooring in Ice Infested Waters
Several design studies have investigated the use of Single Point Mooring (SPM) systems in waters having significant seasonal ice intrusions. Investigations were carried out for both temporary...
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...
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...
Constructibility of Arctic Offshore Structures
The costs of structures designed for Arctic Offshore Drilling and Production Platforms have reached extreme levels. A major component of the costs of such structures is their constructibility....
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....
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 and Fragmentation of Rock Materials by Explosives
Explosives are used in various commercial applications including the extraction of natural resources from the earth and removal of materials for new construction. These applications include...
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...
Well Rehabilitation Using Decision Tree Analysis
The decision tree concept of decision analysis theory can be easily adapted to the water and wastewater industry in making spending decisions for rehabilitation programs, renewal and replacement...
Arsenic Contamination of Private Potable Wells
The results of a series of water testing programs of private residential wells in Pepperell, Massachusetts showed that of 301 wells tested, approximately 12 percent exhibited arsenic levels...
