Air-Water Oxygen Transfer at Spillways and Hydraulic Jumps
Dissolved oxygen measurements are reported for seven spillway structures in the vicinity of Minneapolis, Minnesota, corresponding to 27 individual surveys. The surveys are taken during...
Model for Optimal-Risk Based Water Distribution Network Design
Various models using a variety of optimization techniques were developed for determining pipe diameters, network layout, pump capacities, and other design parameters. The objective function...
Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....
Grand Canyon Water Line by Directional Drilling
The South Rim Village at Grand Canyon National Park obtains its water supply from a point called Roaring Springs which is located approximately 15 miles across the Canyon on the North...
Advancements in Aerodynamics, Fluid Mechanics and Hydraulics
The theme of these Proceedings is Advancements in Aerodynamics, Fluid Mechanics, and Hydraulics. As indicated by the title, the subject crosses disciplinary boundaries and deals with flow...
The Past, Present & Future of Earthmoving Scrapers
This paper is a summary of the history and development and use of earthmoving scrapers. It will also take a look at the future of this type of machine. We'll build the discussion...
Use of In Situ Tests in Geotechnical Engineering
In the past ten years, many new types of in situ test equipment and many new techniques have been developed. The papers in this volume are concerned with applications of in situ measurement...
Effects of High Pressure and Temperature on HCP
A modification of fabrication techniques for cement paste can significantly affect its properties. Specifically, the static compressive strength can be increased over that of specimens...
Ice Forces on Bridge Piers
The force that river ice exerts on bridge piers has been studied in the field and with models in the laboratory. Ice forces are a function of the strength, thickness, failure mode and...
Statistical Analysis of Tellico Dam Piezometer Data
The purpose of this paper is to demonstrate the use of statistical and computer processing methods as a tool for analyzing dam safety piezometric monitoring data. Statistical methods are...
Continuous Loading Consolidation Testing Using a Microcomputer for Control and Data Acquisition
An overview of some of the methods of one-dimensional consolidation testing currently in use is presented, including the load-increment test, the constant rate of strain test, the constant...
Wind Effects on Compliant Offshore Structures
In recent years modern experimental and analytical techniques for estimating wind effects have increasingly been applied to compliant offshore structures. The six papers included in this...
Designing for Flow
Geotextiles used for in-plane drainage can carry surprisingly large amounts of water within their structures. These composite drains, known as sheet drains, prefabricated drainage composites...
Porewater Pressure in Clays Below Caisson Islands
Unfrozen lightly overconsolidated clays are a significant factor in the design and performance of exploration caisson retained islands in the Canadian Beaufort Sea. At two sites (Tarsiut...
A Contractor Looks at Slope Protection for Arctic Offshore Artificial Islands
Some thirty artificial gravel islands for oil and gas drilling/production have been built in the Beaufort Sea since early 70's. Protection of slopes of the islands and causeways...
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...
Soil Strength Determinations from the Cone Penetrometer Test
Geotechnical exploration in offshore Arctic regions often relies upon the electric Cone Penetrometer Test (CPT) because of its speed, economy, data continuity, and general reliability....
Arctic Penetration Test Systems
Geotechnical exploration in offshore arctic regions relies upon the electric Cone Penetrometer Test (CPT) because of its speed, economy, data continuity, and general reliability. By adding...
The Rapid Deployment System: A Method for Conducting In Situ Soil Tests from Moving Ice in The Arctic Offshore
A new system was developed which permits rapid helicopter assisted transport of a light-weight in situ geotechnical testing system to remote offshore sites situated on unstable first-year...
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...
