Translucent Structural Beacon
In East Los Angeles some 2,000 children, teens and adults are accessing their future inside a building that is as high-tech as the computers they are using to learn. The 40,000 sq ft building...

Cable Corrosion in Bridges and Other Structures:
Causes and Solutions
This book provides the reader with basic facts concerning cable corrosion and means to avoid or rehabilitate corrosion damage. Corrosion problems associated with cable-supported structures...

Historical Development of Bridge Scour Evaluations
Scour of bridge foundations (piers and abutments) is the largest single cause of bridge failures in the United States. Conversely, uncertainties of the scour depth at bridge piers and...

Validation of the Simplified Audit Process at a Roofing Tar Paper Speciality Product Manufacturer - Part 2
The Simplified Audit Process (SAP) is presently tested in a roofing tar paper speciality product manufacturer in Joliette, Quebec. The steps involved in the process had helped the company...

Efficient Pump Representation for Fixed-Grid MOC in Pipeline Systems
An explicit solution of the pump power failure boundary condition is shown to have many computational advantages over the conventional implicit pump boundary condition solution (i.e.,...

Bridge Hydraulic and Scour Analysis Using FESWMS-2DH
Stream crossings are usually designed to satisfy all engineering and enviromnental constraints at the lowest possible cost. As a result, roadway approach embankments leading to bridge...

Guist Creek Dam Spillway Upgrade: A Maze (Labyrinth) of Difficulties
Any dam that holds back a large quantity of water is potentially dangerous. Some dams are more of a threat than others, especially those with human populations and valuable property in...

Inundation Studies in Case of Failure of King Talal Dam
In this paper a brief description of the studies is presented and the computed results are summarized. During running the program, several difficulties were encountered. These problems...

Earth Spillway Design Using SITES Software
The USDA Natural Resources Conservation Service has, recently released new software for the design and analysis of water resource structure sites. This software, SITES, is based on the...

Draining Himalayan Glacial Lakes Before They Burst
Glacial lakes are a common feature of the Himalaya in general and the Khumbu Himal region of eastern Nepal in particular. Some of these glacial lakes are naturally unstable because of...

The Timberlake Dam Failure: A Hydrometeorological Assessment
Extremely heavy rainfall over the Timberlake basin in southwest Virginia on 23 June 1995 caused an earthen dam to fail and resulted in fatalities. The meteorological conditions are examined...

Construction of Performance Contours on the Storage-Yield Plane of a Within-Year Reservoir System
The reservoir storage-reliability-yield (S-R-Y) relationships developed in the past have considered only the probability of failure to meet the target requirements, but not the likely...

Design Guidelines for UV Disinfection Facilities
Current design methods for UV disinfection facilities depend largely on experience with minimum input design variables, such as water UV transmittance and required disinfection efficiency....

Numerical Modeling of Flows in Ultraviolet Disinfection Channels
Current design methods for UV disinfection facilities depend largely on experience with minimum input design variables, such as water UV transmittance and required disinfection efficiency....

The Analysis of the Failure of the Minte Stream Culvert
A persistent and continuous rainfall that lasted for more than 30 hours on May 6?7, 1995, caused the sudden failure of an embank ment on the main road between Puerto Varas and Ensenada,...

Assessment and Implications of Local Channel Instability on the Prediction of Bridge Scour
Current assessments of the potential for scour at existing and new bridges do not include the effects of local channel instability on predicted bridge scour estimates. Local channel instability...

Use of Geomorphic Data for Assessing Stream Stability at Bridge Structures
The authors recently completed a statewide bridge scour evaluation for the Nevada Department of Transportation, which included evaluation of the geomorphic processes of bank erosion and...

Constructor Prequalification
Choosing the Best Constructor and Avoiding Constructor Failure
This comprehensive, practical manual illustrates how owners can evaluate and select constructors for various civil engineering projects using the process of constructor prequalification....

Another Times Square Attraction (Available only in Structures Special Issue)
Located in the middle of Times Square, 1540 Broadway has become a prominent fixture in this rapidly changing area of New York. Originally designed by Skidmore Owings Merrill, New York,...

Success or Failure: A Tale of Two Projects
Twenty city blocks and a ten year period separated two projects of similar purposes, but with completely different endings. The first one, the Delancey Street Project, took place in 1984...
