Dispersive Soil and its Influence on the Design of Reach 1A of the Tucson Aqueduct?Central Arizona Project
An extensive geotechnical field exploration and laboratory testing program was conducted because of dispersive and erosive soils along the alignment of the canal. The canal design was...
Design Considerations for a Navigational Channel
The hydraulic feasibility of the proposed navigation channel from Shuwaikh to the offshore area in Sulaibikhat Bay was studied. Channel width and alignment were determined considering...
Artificial Beach Design, Lake Forest, Illinois
A system of beaches and offshore breakwaters was designed to protect eroding bluffs along the shoreline of the City of Lake Forest. The beach system consists of sand fill contained by...
Beach Stabilization Design
There is a need for aesthetically pleasing and environmentally satisfactory solutions for protecting, renovating and restoring eroding semi-protected coastal beaches such as those found...
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...
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...

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...
