Conquering the Mountain
Interstate 26 will be the largest and most expensive highway project ever undertaken in North Carolina. When completed in 2002, I-26 will provide safe and efficient interstate passage...

Probing Pipelines (available only in Geoenvironmental Special Issue)
Inspecting underground pipelines has become easier, more effective and less intrusive through use of sonar, radar, lasers and seismic and acoustic testing. To replace simple visual inspection,...

Coldhearted Building
A 20,000-ton district cooling plant owned by the Public Service Company of Colorado was recently built to sell chilled water to customers in downtown Denver who will use it to air-condition...

Do Coated Pipes Last Longer?
Field studies have revealed that polymer coated steel pipe resists corrosion longer than pipe coated with other materials. Corrosion is the most common failure mechanism of pipe culvert,...

Pipelines in the Constructed Environment
This proceedings, Pipelines in the Constructed Environment, consists of papers presented at the 1998 Pipeline Division Conference, held in...

Corrosion Control
As pipe systems with nonwelded joints have become more common, so have problems with corrosion. It's up to designers to carefully consider corrosion issues in order to avoid...

Manhole Rehab
Using trenchless technology, two construction crews working on the Massachusetts Water Resources Authority's Wellesley Extension Relief Sewer project rehabilitated 83 manholes...

The Pipes Sound Off
Using technology developed by the navy, engineers are now able to determine the condition of prestressed concrete cylinder pipes by listening to the prestressing wires as they break....

Manufactured Gas Plants: Yesterday's Pride, Today's Liability
Manufactured gas plants were the pride of the industrialized world until cleaner, natural gas pipelines were built beginning in the 1930s. Most gas plants had closed by the 1960s, leaving...

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...

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...

Risk Analysis of Joint Reservoir Operation in Central Taiwan
Risk analysis for shortage of water on the joint operation of Li-Yu-Tan Reservoir and Shih-Kang Dam (Reservoir) in central Taiwan is presented in this paper. Deter ministic simulation,...

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...

Pipeline Crossings 1996
This proceedings, Pipeline Crossings, consists of papers presented at the Specialty Conference held in Burlington, Vermont, June 16-19, 1996....
