Permeability, and the Field Pumping Test
Methods of estimating in situ permeability of soils are discussed including laboratory tests, borehole tests and field pumping tests, with emphasis on the latter. Techniques for designing...
Diamond Fork Hydroelectric Power Development
The Strawberry Valley Project was conceived in the early 1890s as an irrigation project to supply a maximum of 635 cfs of water from the Strawberry Reservoir through a 3. 8-mile-long tunnel...
Simultaneous Pumping from Layered Ground Water
Laboratory experiments with a Hele-Shaw model and a sand model, and an approximate mathematical analysis using finite elements and the computer, have demonstrated that fresh water can...
Central Arizona Project Startup
The Central Arizona Project is a water conveyance scheme, lifting and conveying Colorado River water from Lake Havasu on the Colorado River 190 miles to Phoenix and another 150 miles to...
California Water Project Operation
The California State Water Project (SWP) is operated and managed using state-of-the-art operations research and optimization techniques. Medium- and long-range studies for the operation...
Model to Maximize Releases for Supplemental Generation in a Pump-Storage System
An optimization model has been developed to maximize releases for supplemental power generation in a pump-storage system. The model was developed to aid in the scheduling of pump-storage...
Emergency Flood Management, Salt Lake City, Utah
This paper discusses Salt Lake City's response to the floods of 1983 and 1984. Peaks during these years were very high with historic records being set in both years. Management...
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...
Orleans Parish Drainage Improvements
A case study of the development of an urban drainage master plan for Orleans Parish, Louisiana is presented. The Parish, which occupies an area of approximately 98,000 acres, lies entirely...
The Tunnel that Cleaned Up Chicago
The 1986 Outstanding Civil Engineering Achievement award went to Chicago's Tunnel and Reservoir Plan (TARP) Mainstream Tunnel and Pumping Station. The $975 million project...
Alternate Sewers�No Longer Alternate
The term alternate sewers means those used where neither conventional gravity sanitary sewers will suffice, nor will the septic tank/leach field system. In such situations, usually one...
Bicycle Access: New Boost for Transit Performance
Bicycle-transit linkage is a highly cost-effective strategy for boosting suburban transit performance and ridership and appears to offer significant potential for reducing transit access...
Initial Operation Model for the Central Arizona Project
A microcomputer program for operating uncompleted portions of the Central Arizona Project has been developed. Engineers may use this program daily to assist in scheduling pumping plant...
SRC Elevated Station Structures for New Bullet Trains
SRC Steelframe reinforced concrete structures were utilized on several station buildings for the Japanese National Railways bullet trains. This paper presents an outline of the dimensions...
Modelling Complex Water Distribution Systems
A program previously used for the analysis of hundreds of water distribution systems was successfully modified to provide the features needed for the extended simulation of large complex...
Computerized Design and Selection of Pumping Systems
Three computer models have been applied in the evaluation, design and selection of a high-lift pump station upgrading program developed for the City of Poughkeepsie, New York. The three...
Computer Control of Lift Station Operations
A unique computerized control system to supervise the operation of several lift stations has been designed by Boyle Engineering Corporation (Boyle) and constructed by the City of Orlando,...
The Edwards Aquifer in the San Antonio Area
The Edwards Aquifer in the San Antonio area is a highly productive groundwater system consisting of the Edwards Plateau water table aquifer and the Edwards Balcones fault zone artesian...
Building in Space
Work on the nation's first permanently manned space station has begun. Almost $200 million in contracts for conceptual design for the station were awarded by the National...
The Tunnel That Transformed Philadelphia
The 1985 Outstanding Civil Engineering Achievement is the Center City Commuter Rail Connection, a 1.7 mile tunnel connecting two former stub-end railroad stations in Philadelphia. The...
