Irrigation Canal Seepage and its Measurement
Reduction in seepage is one of the primary reasons used to justify investment in canal lining. Such justification depends greatly upon estimates of seepage through surface and subsurface...
Incorporating Crop Water Use in Drainage Design in Arid Areas
A method of drainage design for use in arid areas was developed by combining procedures proposed by D. B. McWhorter along with plant uptake functions developed by D. W. Grimes and D. W....
Risk Analysis for Ship-Bridge Collisions
The authors have developed a propriety software package which has been successfully used to perform risk analyses for several high-level bridge structures across major waterways in coastal...
New Orleans Flood Gates Hydraulic Model Study
A hydraulic model study was conducted to evaluate the forces exerted on selected floodgates by flowing water as the gates are closed after flooding has begun. The results of the study...
Hurricane Diana: Impact on Coastal Development
Hurricane Diana affected the coast of North Carolina during the period of September 11-14, 1984. Builders, designers, building officials and insurance adjusters responded to a written...

Recent Developments
The Foothills Project has been under consideration by the Denver Board of Water Commissions for many years. It is one of the major steps in the continued efforts of the Board to provide...
Micro-CAD Systems: A Dream Come True
Computer-aided design and drafting systems that run on inexpensive microcomputers are examined. Several major systems (products) are covered via the users point of view. Many small civil...
Get Involved with Cladding Design
Structural engineers should get involved with cladding design for their buildings. Including disclaimers for responsibility in the design contract will not prevent trouble or lawsuits,...
Bridging Twin Ports
The Major Richard I. Bong Memorial Bridge, part of U. S. Highway 2, connects harbors at Duluth, Minn. and Superior, Wisc. The new highway link was designed to relieve congestion on nearby...
Who Should Design Bridges?
For many years Design-Build-Proposals have been common practice in Europe (except in the UK). Structures in these countries are 20% more economical than similar projects in the U. S.,...
Effects of Vehicles on Buried, High-Pressure Pipe
The mechanical effects of selected types of traffic on buried, high-pressure steel pipe are examined. Particularly considered is a section of the Colorado Interstate Gas (CIG) pipeline...
Influence of Depth-of-Cover on Pipe-Soil Interaction
A major research effort was undertaken to study the structural behavior of a natural gas pipeline under several critical service conditions. The program included a field test site near...
An Instrumented Soil-Pipe System: Automated Data Acquisition and Management
A 16-in. natural gas pipeline near Racine, Wisconsin, had been in service for some 30 years. In 1982 road widening operations on a line parallel with the pipe resulted in a heavily trafficked...
Metal and Plastic Pipelines: Design and Construction Aspects
This paper discusses design and construction aspects of four cross-country pipelines that were built in central Alberta, Canada during 1982-1983. The first two pipelines, carrying different...
The Evolution of Jointing Vitrified Clay Pipe
Advances made in the jointing of vitrified clay pipe during the last half century, illustrate the concern of the clay pipe industry to provide top quality jointing methods. Early 19th...
Sewer Construction Inspection and Testing
Sewer construction testing is the final portion of the team effort that started with the goal of meeting the requirement for a sewer system for the protection of health and environment....
SPIDA: An Analysis and Design System for Buried Concrete Pipe
The paper presents a description of a new computerized direct design method for buried concrete pipe named SPIDA (Soil-Pipe Interaction Design and Analysis). Also the technical basis and...
Experiences in Concrete Pipeline Construction in Ontario 158-1985
The paper discusses the title subject in terms of concrete pipe fabrication methods and plants, pipe jointing and jointing materials, and construction experiences in the Province of Ontario,...
Alternative Approaches for Waterhammer Analysis and Pipeline Protection
This paper provides a brief review of typical waterhammer problems and their solutions for pumping systems. Alternative approaches to identify and resolve design problems are discussed....
Longitudinal Prestressed Piping for District Heating
The design of recently installed hot water district heating systems in the United States is based on similar systems developed in Europe. Longitudinal prestressing is used in the design...
