Making Water System Rehabilitation Decisions
Making decisions regarding water distribution systems has always involved a great deal of judgment due to the complexity of the decisions involved. This paper presents a framework for...
Simplified Prediction of Storm Surge on an Open Coast Using a Microcomputer
Computer-generated wind fields have a flexibility that is not available with standard manual procedure; i. e. different illustrative concepts can be given a trial run at low cost. A spreadsheet...
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...
Utopia Under Glass
We stand within sight of the day when our reserves of fossils fuel will be inadequate to maintain the type of energy inefficient cities we have grown used to. This exercise in urban planning...
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...
A Study of Exterior Facades?Problems and Solutions
The quality of the exterior facades of a building is important to maintaining aesthetic image, protecting the interior environment from infiltration of heat, cold, moisture, wind, and...
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...
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...
Interactive Microcomputer Analysis and Design of Light Gage Steel Roof Systems
A hinderance to the widespread acceptance of the cold-formed steel roof Z-purlin in conventionally engineered buildings is due to the lack of a useful and efficient analysis and design...
Technology Assessment for Hydrogen from Renewable Energy
This paper is a preliminary report on an assessment of technologies for hydrogen production from renewable resources, and an investigation of the problems and issues involved in assimilating...
Developing Renewable and Alternative Energy Sources
The development of small scale, renewable or alternative (R/A) energy resources was originally perceived as environmentally more acceptable than large-scale conventional projects. The...
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...
The Concrete Diagonal
Onterie Center in Chicago, Fazlur Kahn's last major structural design, is a companion in concrete to the diagonally braced steel John Hancock Center. It is a mixed-use building...
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...
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
