Type Curves for a Slug Test in an Infinitely or Semi-infinitely Thick Aquifer
Type curves are provided for a slug test in an infinitely or semi-infinitely thick aquifer, the latter with the single confining layer immediately above or immediately below the well....

Aquifer Measurements at Different Scales
Multilevel slug test data from five wells in a confined, sandy aquifer were analyzed to obtain an estimate of the vertical variation of the horizontal hydraulic conductivity, K(z). Hydraulic...

Application of Tracer Tests in Groundwater Remediation Design
Recent advances in the area of field testing for the quantification of hydraulic conductivity have resulted in improved site characterization of aquifer hydraulics and greater reliability...

Effect of Nile River Flow on Performance of Shoubrah Power Plant Cooling System
Shoubrah El-Khimah Power Plant was built in 1982. Its peak capacity is 1200 MW, generated by four units, three of them having one cooling water intake. The cooling water pumps suffer from...

Pump Station/Storage Opportunities for Urban Freeway Systems
This paper introduces the concept of utilizing underground storage to minimize both the initial cost and the long-term maintenance and operation costs of multiple pump stations for a freeway...

Optimizing Regional Detention Basins for Price Expressway
Stormwater runoff from the drainage area contributing to the Price-Santan Freeway is captured in regional detention basins which require a series of pump stations for evacuation. With...

Animation of Automated Space Construction
This paper presents a discussion of Three-Dimensional Computer Animation as applied to the evaluation of Lunar/Mars construction. A number of applications for this type of tool are introduced....

Epilimnetic Dissolved Oxygen Content and Surface Water Pump Performance
Surface water pumps have been operated and monitored at TVA's Douglas Dam since 1987. The purpose of these pumps is to improve the dissolved oxygen (DO) content of the hydropower...

Scenario for Improving the Seismic Resistance of Pipelines in the Central United States
A number of pipelines transporting crude oil and natural gas to the Midwest and Northeast pass within and adjacent to the New Madrid seismic zone in the central United States. A major...

Earthquake Loss Estimation of the Portland, Oregon Water and Sewage Systems?Evaluation of Concentrated Facilities
This paper summarizes a report that provides an inventory of concentrated water and sewage facilities in two selected drainage basins in the City of Portland. Concentrated facilities include...

Seismic Vulnerability of Memphis Water System Components
The vulnerability of selected components of the Memphis Water System is evaluated herein for a 7.5 moment magnitude earthquake within the southern portion of the New Madrid Seismic Zone....

Seismic Vulnerability Analysis and Upgrade of Seattle Metro Wastewater Facilities
The Municipality of Metropolitan Seattle, Metro, provides wholesale wastewater transport and treatment for 30 cities and sewer districts. A Seismic Vulnerability Assessment Worksheet for...

Riverbank Renewal
In Providence, project teams from the public and private sector worked side-by-side, rerouting two rivers and constructing a new corporate headquarters. What made the task more challenging...

Putting It Back
Before construction of the largest inclined turbines in the U.S., the Santa Ana River would carry storm flows out to sea, lost to the residents of water-poor Orange County. The area's...

Pumping Oil, Treating Soil
Oil was discovered on hilltop land in Signal Hill, Calif., in 1921, setting off one of the most wild land rushes the state has ever seen. Some 70 years and 20,000 oil wells later, the...

Space Station Freedom Requirements for Structural Safety, Reliability and Verification
The Space Station Freedom (SSF) is a large, manned vehicle that will be designed to remain in Space for 30 years. The SSF Program has established extensive safety, reliability and verification...

Incremental Assembly Stage Concepts for Space Station Freedom: Structural Design and Verification
The design and development of the U.S./International Space Station Freedom poses extreme technical and management challenges to the NASA/industry team. A comprehensive system engineering...

Space Station Freedom Pressurized Module Meteoroid/Debris Protection
Protection of spacecraft from the effects of a meteoroid/debris particle impact can add significant weight to the required structure. This paper discusses the meteoroid and debris environments...

Pressure Vessels for Space Station Freedom
