Turnback Project Moves Ahead
The $202 million Muni Metro Turnback (MMT) Project, scheduled for completion in September 1996, includes an 840 ft section consisting of twin steel-lined tunnels that connects to the Embarcadero...

Rehab by Helicopter
The City of San Diego's 86-year old Dulzura Conduit has been in almost continuous operation since it first opened in 1909. But by 1984 flow had been reduced to less than 15...

Plumbing the Quality of a Sewer System
Consultants in Phoenix were recently charged with assessing the city's sewer system, many feet of which were laid without plastic lining to protect them. Developing a capital...

Structural Aerodynamics (Available only in Focus on Structures Special Edition)
One of the most strikingly ambitious public buildings in France, county governmental headquarters in Marseille, achieves the status of world-class architecture largely through its structural...

Seismic Solutions for Steel Frame Buildings
After the Northridge Earthquake, damage in steel moment resisting frame connections stunned engineers. Now those engineers are scrambling to find and test new kinds of connections. This...

Spotlight on Steel Moment Frames
Engineers' confidence in moment connections was shattered when damage was discovered after the 1994 Northridge earthquake. Such connections are now a hot subject for U.S....

Catching Up on Composites
Until recently, Japan and Germany were way ahead of the U.S. in composite material technology for construction. Lighter, stronger and possibly more durable than conventional materials...

Boston's Third Harbor Tunnel (Available only in Focus on Geo/Environmental Special Issue)
Boston's immersed marine tube, the Third Harbor Tunnel, connecting South Boston and Logan Airport, is a $226 million component of the multi-billion dollar Central Artery/Third...

Dam Foundation Erosion Study: The Design of a Sidewall Orifice for Simulation of a Free Trajectory Overtopping Jet
This paper describes the design of a sidewall discharging orifice for simulation of a free trajectory overtopping jet. A sidewall orifice discharges through the sidewall of a pipe. The...

Genetic Algorithm Design of Piped Irrigation Systems
The design of piped irrigation systems is a complex matter. In its simplest form it involves the selection of the sizes of pipes and other hydraulic elements so as to ensure that the varying...

Grade Control Structures for Pipeline Crossings in the Arid Southwest
Pipeline crossings at streams, rivers, and washes are at risk due to bed and bank erosion in the river environment. Buried pipelines may be exposed in the channel bottom by scour of bed...

Pipe Network Analysis and Design in Developing Regions. Case Study: Novokuznetsk, Siberia
Pipe network analysis, design and optimization in developing countries poses some unique problems, yet, is of paramount importance. Under these conditions, there is frequently only sparse...

Protecting Dredged Material Containment Levees along the Houston Ship Channel
This paper describes the background, selection, installation, and performance of the three-dimensional woven geotextile used for erosion protection along 122 meters (400 feet) of levee...

Dam Foundation Erosion Study: Pit 4 Scale Model Simulation
This paper describes the results of a sub task of the Dam Foundation Erosion Study, a cooperative research study by Reclamation, PG&E, Colorado State University, and Western Area...

Physical Modeling to Determine Head Loss at Selected Surcharged Sewer Manholes
The head losses at sewer pipe junctions (manholes) under surcharged conditions were measured in a 1:6 scale model of a typical manhole with one main line passing through it and two perpendicular...

The Costs and Benefits of Dam Removal on the Elwha River
The Elwha River is located on the Olympic Peninsula in the State of Washington. In the early 1900s two hydroelectric dams were built on the Elwha River. Construction of Glines Canyon and...
