The Great Highway Coverup
Public opinion has forced changes in highway design since the first ones were built 30 years ago. In the Seattle area, this environmental sensitivity led to federal court action and to...
Coastal Flood Control Facility Design Parameters
The development of design parameters for a storm runoff detention facility located on lowlands adjacent to an estuary and discharging into the tidal zone are discussed. The parameters...
How to Provide Shoreline Public Access
Methods of providing access facilities are covered which range from outright acquisition, obtaining public easements, and converting street ends to conditioning development permits. The...
Analysis of Plastic Soil in Contact with Cavitose Bedrock
A numerical analysis has been conducted to evaluate the stress deformational response of highly plastic soils in contact with cavitose Bedrock. The numerical idealization represents the...
Plastic Concrete Cutoff Walls
The studies revealed that plastic concrete can be prepared having a coefficient of hydraulic conductivity that is less than 1 multiplied by 10** minus **7 cm/sec. The shear strength of...
Seismic Analysis of Safety-Related Nuclear Structures and Commentary on Standard for Seismic Analysis of Safety Related Nuclear Structures
This standard provides requirements for performing analyses to obtain design information which will lead to the reliability of structures under a severe earthquake. The goal of this standard...
Guide for the Design and Use of Concrete Poles
Prepared by the Concrete Pole Task Committee of the Committee on Electrical Transmission Structures of the Structural Division of ASCE. This guide presents...
Foundations and Excavations in Decomposed Rock of the Piedmont Province
The five papers in this volume deal with foundations and excavations in the Piedmont Province of the USA. This is a region underlain by very old metamorphic rocks that are overlain by...
Making Embassies Safe for Democracy
American interests overseas have become among the most popular targets for terrorist attacks. Once, not long ago, security was only an afterthought for such facilities. Today, $4.4 billion...
A Safer Earthquake Design Approach
The Uniform Building Code earthquake code permits taking advantage of a frame's capacity to absorb energy at stresses beyond yield. Dropping that provision would save lives....
Historic Bridges: Conflict Ahead
The engineer who deals with historic bridges becomes the focus of controversy in the course of determining the existing condition, predicting remaining useful life, and designing the repair...
Electronic Gymnastics
Efforts are being made to have all the parties to a project share the same, current information. In order to do so, civil engineering firms are jumping through electronic hoops to get...
CAD Trials
The solo practitioner is, for many reasons, at a disadvantage when it comes to analyzing and selecting CAD system components. Trade magazine how-to articles are generally geared toward...
Automating Bridge Design
To avoid some of the pitfalls of manual design calculations, Parsons Brinckerhoff Quade & Douglas engineers designing a series of bridges for a $280 million section of the New...
Design of Large Steam Turbine-Generator Foundations
This report is a guide for engineers who are responsible for the design and analysis of large turbine-generator foundations. A description of the various components of turbine-generator...
Neyrtec Automatic Equipment for Irrigation Canals
The French Company ALSTHOM has developed a line of simple equipment for automatic level control and constant discharge control in canal irrigation systems. The paper includes a description...
Pipeline Types and Design Considerations
Pipelines are extensively used to upgrade irrigation delivery facilities. The advantages of a pipeline system include an improvement in water conservation and the ability to extend water...
Design of Semi-Closed Pipeline Systems
Semi-closed pipeline systems controlled by downstream activated float valves permit low pressure pipeline systems to communicate information from the outflow location back to the source...
Pump Plant Control and Automation
Pumping plants for irrigation systems can be separated into two general types: source pumps which provide water to the system and booster pumps which increase the system pressure. Typically,...
Evaluation of and Recommendations for Drop Structures in the Denver Metropolitan Area
In 1982, the Denver Urban Drainage and Flood Control District published interim guidelines for the design of sloped, loose riprap drop structures, as well as vertical wall drop structures...
