San Francisco CSO
Today, even a light rain can overload San Francisco's combined sewer overflow (CSO) system, sending untreated sewage and stormwater into the bay and ocean. This is especially...

Taming the Red River
The U.S. Army Corps of Engineers completed its last great waterway project, the Red River Waterway in Louisiana, Dec. 31, 1994. The project took more than a quarter of a century and $1.8...

Guarding Against Scour
An overview of the magnitude of the bridge scour problem in the United States is presented, using recent bridge failures to illustrate the problem. Procedures and results from the ongoing...

Beyond Water Witching
Ground-water exploration is usually an uncertain and expensive endeavor. Since late 1993, however, Golder Associates Inc., Redmond, Wash., has been working with time-domain electromagnetics...

Designing for Drama
Near the Passaic River in Newark, N.J., not far from the famous Iron Bound restaurant district and Newark's Penn Station, construction crews swarm around the steel skeleton...

Restoring a Stream Corridor
The Stream Restoration Project is an environmental remediation project in a residential area in the Northeast United States. The soil in the flood plain of the stream was contaminated...

Removing Metals From Soil
Metals-contaminated soils have been among the most intractable hazardous-waste remediation problems. Conventional mitigation methods of capping, stabilization and landfilling all have...

Case Histories of the Design, Construction, and Maintenance of Rubble Mound Structures
This proceedings, Case Histories of the Design, Construction and Maintenance of Rubble Mound Structures, contains papers presented at a seminar...

Flood Control Doesn't Have to be Ugly
The recently completed flood control project in Rochester, Minn. shows how innovative engineering combined with aesthetically-sensitive design can integrate flood protection into an urban...

Divided We Fall
This article examines the aftermath of a falsework failure during the construction of a Mississippi River bridge in Minnesota. The author reviews the legal issues that arose from the collapse,...

Rising from the River
The Corps of Engineers completed construction of a 20 Million cu yd dredged material containment facility in the Delaware River in 1990. The authors examine the performance of the geotextile...

Calendar: Bridges 1996
Featured bridges are: Big Four Railroad Bridge (KY); Germantown Covered Bridge (OH); George Street Bridge (IN); Virgin River Bridge (UT); Bryan Bridge (NE); Brush Creek Bridge (KS); Natchez...

Money-Saving Model
Determining whether dams and spillways along a river are adequate to handle potential floods can have far-reaching financial, as well as human ramifications. Watershed modeling studies...

Behavior of Foundations Subjected to Large Ground Movements
The behavior of twelve linear test foundations above an advancing longwall coal mine panel was observed. Three phases of deformation were observed in the centerline foundations: tension,...

Stability of Lift Slab Structure During Construction Stage
The lift slab structures impose stability problems during the construction phase. The process of constructing this type of structure requires placing the masses of the floor slabs at a...

Seismic Evaluation of the Tied-arch Bridge Across the Mississippi River on I-40
The bridge reported in this paper is a two-span steel tied-arch bridge supported on massive caisson foundations. Site specific seismic studies were carried out to establish the ground...

Construction of the Clark Cable-Stayed Bridge at Alton, Illinois
The Clark Cable-Stayed Bridge crosses the Mississippi River at Alton, Illinois. The successful bid by McCarthy Bros/Clark Bridge JV was for the steel alternative. The bridge design included...

A Generalized Approach to the Local Stability of Stiffened Plates: Part I?Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...

A Generalized Approach to the Local Stability of Stiffened Plates: Part II?Approximate Solution
The paper presents an approximate solution for the prediction of the buckling stress of stiffened plates under combined loadings. A closed form expression is presented for the buckling...

Phoenix Central Library: Reading Room Roof
This paper discusses the design and analysis of the cable truss roof over the fifth floor reading room of the new Phoenix Central Library. Forty pairs of diagonally oriented cable trusses...
